Prepping For Calgames

Hey everyone!

Sorry for the recent lack of posts, we've been fairly busy within the build area in preparation for Calgames. I hope this video of our tested climber makes up for that! (Because of where I got the video, it appears strangely large on the blog, but I assure you that is what is supposed to happen)

2 Meetings, 2 Comentators

Hey all!


Allen and Hailey here, bringing you all an update on the last two meetings! Our team met last Sunday and this Wednesday night to continue prepping Oddjob 2.0 for Calgames. There’s so much to tell you all!


First off, we had students CAD away. Some worked on creating the electronics board using Solid Works and our Mechanical VP created a hook to use for our new piston operated climbing system. Evil Mad Scientist’s were able to create these hooks for us and are beautifully displayed in one of the pictures below.


Our software group are teaching the rookies how to program with the arduino platform, which uses C++ like a language. It’s always good having new members showing an interest in something we do and having older students helping to teach what they know.


Mechanical members mainly focused on modifications of Oddjob 2.0 and the fabrication of a new table stand to place the robot on. For Oddjob, the battery , mounting was thoroughly debated and our new frisbee shielding shortened to allow for safe passage beneath the 30in bar of the pyramid.


To those of you interested in watching Cal Games, there is more information regarding it on our team website: http://fremontrobotics.com/


Well thats all the updates! This has been Hailey and Allen, signing off.

Meetings With 10x More Things Done!

Hey All!

Allen here again with another update on the wonderful life of team 3501! Today we completed a bunch of things! First off, a group of veterans wired up the new circuit board for the robot since we had downsized Oddjob. Our rookies completed the base to hold up Oddjob 2.0 so that we can bask in its glory. Then our programmers needed to test some codes and so they decided to begin building a new drive base. While everyone was off with their own jobs,  our wonderful president attached the the new and improved feeder onto the robot. Finally, we had a few members measure our school's large gym and small gym in order to prep the court for Cal Games. The pictures below are examples of what we have completed! Sadly, this comes to the end of our update. But fear not, there's more to come!

Until next time, this is Allen, signing off.

More Meetings! With 10 times More Heat!

Hello All!

Allen here with another update! Yesterday's meeting was yet another fun filled day! We had a few rookies joining us today and most likely there will be more at the next meeting! During the meeting we had accomplished several things, by using a strip heater we were able to bend the plastic into the shape we wanted it to be. As seen in the picture below, the shape of the plastic helps guide the Frisbee into our shooter, keeping it upright as well (most of the times at least). Several people had the most wonderful adventure, searching for a leak in our pneumatic systems as it was discovered on our Sunday meeting. Oddjob received a few upgrades, becoming Oddjob 2.0. Now with 75% less height and 50% lighter (for now of course). We also had a lunch meeting for all the new comers and gave them the run down of what happens in robotics. As a reminder to all incoming team members there is a "request" of $50. Well that's it.

This is Allen, signing off. Until next time everyone!
That's one small robot!

Three Days of Fun

Hello readers!

Our team has had quite an exciting three days! We've come in for hard work on the robot and had a company visit. First I'll talk about the changes we've made to Oddjob and then about the wonderful tour of NDC, Nitinol Devices and Components.

After much debate and discussion, our team had decided to go forward to a nearly complete reconstruction of the robot. We had a towering height originally designed to accommodate a 30 point climbing mechanism. However, that design fell through due to the amount of weight and we stuck with a simpler 10 point climber and height. Now that we are in the off season and preparing for Calgames, we have begun on reducing that unnecessary height from about 48 inches to now around 20 inches. This drastic height change we've worked on now for two days does present some draw backs. The electrical team now needs to redesign the electrical board to fit in a new  space and the mounting of the shooting will also need fixing. These however do not even come close to the pros of this whole operation. Our smaller height will allow our drive team to move  more easily around the field and be able to travel underneath the pyramid, something we were not able to accomplish before. Along with the change of height, our team also plans to fix our drive train's gears and add a set of omni directional wheels. Team 3501 has it's work cut out for it, but I believe we can get all of this done! :)

Yesterday, August 7th, eight of our students and two of our mentors had the opportunity to visit NDC, Nitinol Devices and Components, in Fremont, California. Previously known as Nitinol Developement Company, they were founded in Fremont 20 years ago and have been a booming business competitor since. They are one of the world's 3 major nitonol manufacturers. Nitinol is a nickel titanium alloy with some very unique properties. For anyone familiar with bendable glasses or muscle metal, that is nitinol. What I found most extraordinary was that this metal can be trained to act or expand into the shapes desired by the developers. NDC workers has used their 20 years of experience to perfect the developing techniques of their products. One fine example is medical stents. They have to make sure their products do not harm patients with metal allergies and function properly under the conditions in a human body. They test stents made for arteries and make sure the surface won't interfere with the artery while also testing for fatigue. My favorite part of the tour was probably seeing their machine shop since I am also a pat of the mechanical team. Seeing how they problem solved to create machinery they needed for the development of their products was amazing, like how roughly 90% of their machines was constructed and built by NDC workers. I believe I am speaking for everyone present, this company visit was amazing and we can't wait to tell the rest of our team about our experience.

Last but not least, pictures! I will be including photos from both the company visit and our work in the build area.

Hailey Sanidad

Our tour guide Craig showed us samples of the nitinol products they produced before giving us the company tour.
A wonderful team trip, and we'd love to stay in contact or visit again!
Here we see all that we have removed from Oddjob to get a smaller height
Yep, our new height is roughly 20inches :)
We will have to calculate and create a new feeder system
Last but not least, we began working on the pnuematics for the climber and for the shooter to be attached to our smaller robot

Hey All!

Allen here bringing you an update on our meetings! During our meeting, we made some drastic changes to our piston mechanism for our shooter. The president and mechanical lead were having discussions about the pros and cons of lowering our shooter which will be decided on a later date. The little piston we had for our shooter has been replaced with a larger one. Our website has received several changes and some of our teammates are making a safety poster! We are also currently making some plans for the CAL Games which is being held by our very own school! That's all folks!

Until the next post,

Allen

Summer Meeting Galore!

Hey all readers!

Today was another fun filled summer meeting in our new build area. The team has been focusing on preparing for the new season and fixing the issues we've had with our robot so Oddjob's ready for Calgames in October. The focus of our work today was our second drive base and Oddjob's disk jamming problem. For the jamming problem, the spinning wheels would cause the chamber in which the disks lay to vibrate fervently. Couple that motion with the possible driving scenarios, the disks would slide over each other and prevent the piston to launch the first disk. The solution we are currently working on is a small wedge to attach to the piston that will allow disk to properly launch while preventing the same overlapping issue. However that is only one possible solution to the jamming problem and we are still considering other alternatives. In regards to the second drive base, we are trying to build a system with a 6 wheel center drop for driving and programming practice along with the challenge of building the drive base. The center two wheels will remain in contact while the other two in the front and back of those wheels can contact the floor and stabilize the robots driving if need be. This would have been extremely useful in the competition two year ago of "Rebound Rumble" with the barrier in the field and the hope of our team is to see if this base can be useful in future games. So the construction of that base has begun. With those both being underway, I'm  thoroughly excited to see what they will look like when completed!

Lastly as my team mate Allen promised last time, pictures!

Hailey Sanidad

Another Summer Meeting Down!

Hey All!

Here's an update on what we have been up to! We are going to change up our robot for the upcoming Calgames and fix all the problems that we had during the Silicon Valley Regional. We split into several groups, one is currently trying to fix the problem where our shooter would jam. Another is teaching our newcomers the basics of building a robot and having them build a new drive-base for testing. Also, the hunt for the perfect bolt for the drive-base has begun.  Well that's about all we did this meeting, stay tuned for more updates!
Sadly no pictures from this meeting, but there will be some next update!

Let the Prototyping Continue

Hello Readers! I hope to keep you updated as we continue moving forward.

Today we had a lot of people and projects going on in our build area. I got to say that we are heading off with a great start for this year. We have lots of members ready to work and here is what we did! :D

Mechanical people worked on a prototype for the shooting mechanism. After the design for going in a circular motion around a wheel mostly failed, we moved onto a straight edged shooter. We had better results than before with the circular design. There are still a fair amount of bugs we need to work out, but I sincerely believe we are heading in the right direction. We also had some Mechanical group members start brainstorming designs for a mechanism to climb the pyramid and one to pick up fallen discs.

Electrical people mostly focused on taking apart some of last years robot. I believe they did this to get the electronics board from last year, which was built thoroughly into the chassis. They also worked with the Software group to start preparing the field elements for this years game. Namely, they began to cut the pipes we shall be using to make our steel pyramid.

I have some pictures that I will compile from the past few days. Keep an eye out for when I post them XD

The Day After Kick-off

Another busy day today, the first of many to come during this six week build season.

As I have mentioned before in a previous email, our team structure is divided into a variety of groups. Our team consists of  a Mechanical, Electrical, Software and PR/Business groups. Each group is working hard now to prepare, plan and design for this years game. Since I fall into the Mechanical Group, I do not have extensive knowledge as to what the Electrical and Software groups are currently working on. I believe they were doing some inventory for our build area and going over last years robot for comparison.

The Mechanical Group has partially broken down into three sub groups for prototyping purposes. We have divided so there are some who will focus on designing and prototyping a shooting mechanism, some on a climbing mechanism and some on a disc gathering system. Today, everyone in the Mechanical group mainly focused on prototyping a system for shooting. Prototyping was done for a plausible design for a shooter. I would say, it was enough for us to do some testing but nothing really concrete. I hope we do more testing and a better prototype tomorrow. We will also likely test other types of shooters than the one we have currently designed. I will post photos by Wednesday. It would be easier for me to explain the prototyping we have done so far with the photos, so I hope to explain that then. Also we may change our prototype design so look forward to it. I will try to have a member of the Electrical or Software Group to post on this blog with me.

Kick-Off 2013 Ultimate Ascent

Wow, yesterday was Kick-off and boy was my team busy! I apologize because that is partially the reason why I did not post anything yesterday. So, let me catch all of you wonderful readers up with what my team has been doing.

In the game Ultimate Ascent, we must design a robot that can shoot frisbees into goals of various heights. For bonus points, our robot has to be able to climb a steel pyramid of sorts. That is the simplest way I would describe it. Here are the links to the animation video and the manual as well.

FRC Manual
2013 Ultimate Ascent Animation

After the live broadcast of Ultimate Ascent, we immediately began brainstorming. Most of our team was assembled in room 127 at Fremont High School. We waited for our team mates at SJSU to come back with the kit of parts. Using the computers at our disposal, we researched about previous years games that had similar challenges to this years. We also started looking for clarifications on different aspects of the game in the manual.

When everyone had returned, we continued to brainstorm strategy. Our focus of discussion was how to score points and what design of a robot would accomplish that scoring.A climber robot that mainly focused on getting the extra points from getting onto the pyramid had the most points but was also going to very difficult to design and construct. A shooting robot that mainly focused on shooting would not be as difficult but would require more programming and accuracy. There are pros and cons to every design, our team discussed many of them.After getting a base idea of what we want our robot to do, which is to be able to shoot and climb to some degree, we ended for the day. We are meeting again at 1pm to continue to discuss, possibly build field elements and design some prototypes for testing. I will post more pictures and plans after today meeting.

The Night Before Kick-off

The time is here! Kick-off is upon us!

As I have said before, one the most important and exciting events of the FRC, FIRST Robotics Competition, is about to occur. Now I'm going to tell you what my team plans on doing.

We are going to have ten students and mentors go to the "local" Kick-off at SJSU to see the presentation for this years build season. They will also be picking up our kit of parts. The kit of parts are parts that FRC and other supporting companies donate to each team every build season. I believe this year they will be including a new and very useful belt system that we can apply to the drive train of our robot.

The rest of the team will be meeting at Fremont High School in Sunnyvale to see the live broadcast of the kick-off. We will be brainstorming and discussing ideas about the kick-off while we wait for the members at SJSU to return. From there, it shall be a large group discussion and brainstorming. The broadcast is at 7 am and we will probably be brainstorming until 5 pm. This events starts the whole time consuming and crazy fun season of Robotics.

Hopefully, I will have the time once the season starts to continue updating this blog on what my team accomplishes. If I can, two or three updates a week would be ideal along with an end of the week summary. We are given six weeks to brainstorm, design, build and test a robot. I know it seems like a lot of time, I thought so my first year, but those six weeks go by in the blink of an eye.

Counting Down to Kick-off

One of the most important and exciting events of our robotic season is almost upon us!

That's right! Kick-off is only 3 days away and counting. :D

First let me explain a bit more about Kick-off and why it's so important. Our club participates in the FRC, FIRST Robotics Competition, and Kick-off is the day when FIRST, For Inspiration and Recognition of Science and Technology, gives every team the new task for the build season. We watch a video explaining what we have to design a robot to do and then we have six weeks to build the robot. After the six weeks are up, our robot is bagged and tagged until the competition. At the regional competitions, you often a partnered up with two other robots to form an alliance and then your alliance competes with another alliance. All of it is crazy fun and can be difficult, but there is nothing I would exchange it for.

I tried to simplify that as much as I could, but if you still don't understand just ask. Also, here is the link to FIRST's website regarding Kick-off. FIRST Kick-off

P.S. I look forward to when the countdown is 3 days 5 hours 0 minutes and 1 second because that is our team number.
