This was our first competition, and it surprisingly went really well. We were surprised that our robot worked so well; it performed on autonomous period by dropping 5 batons into the flat goal, and it also performed during the teleop period. We had multiple teams try to block our robot, but they were all unsuccessful. You can’t block an omnidirectional robot! :) The play by play went like this: our robot dispenses its 5 batons into the flat goal while our partner somehow gets to the other side of the field. Then the teleop started. Our robot takes off and drives sideways and backwards (yeah omni-bot), and takes to the bridge. We usually drive right over the bridge, then go to the dispenser to get 5 batons. We were so surprised that we were the only team that could dispense batons! We got our 3 batons (we didn’t usually get all 5) then we drove to dispense into the rolling goal. That was another thing that was surprising, we were one of the only teams that could dispense into the rolling goal! We won 3 of our 5 rounds, only losing 2 because of issues with the Samantha module, and wifi glitches. We were even on first place for a little bit (4 minutes…). We are hoping to attend the regional competition in the future, but we aren’t sure if we will be able. Good luck for the rest of your season!

Motor Encoders

Here it is! Only $35....

While looking up to buy new encoders on the Tetrix website, I found out that the encoders will cost us $80 a piece. Now…working with Arduino before, I know that good motor encoders only cost around 30-40 dollars each, so something is significantly wrong here. I looked up the part number that is written on the motor encoder, and found that the supplier is US digital. I found that they have a page for “replacement parts” for FRC, which just happen to be the motor encoders that are used for FRC and FTC (they are the same ones)! I’ve posted a link in FTC resources for where to find the inexpensive ($35) motor encoders, and now I can buy 2 motor encoders for what would it have costed me for one.

First night in Boston

Setting up field

Setting up the field

Wow…today was awesome. We broke down our portable field to bring to First night in Boston, and left at around 10:30 in the morning. Surprisingly no one got lost on the way to the Hynes convention center in Boston. We arrived at the convention center, then had to wait around for the loading dock to open to bring in our minivan filed with FTC field parts. The team members went ahead through the main entrance to meet the parents at the loading dock, only to find that it would take us going through nine different people to even get permission to go to the loading dock (we would especially like to thank Team #1 Unlimited’s mentor for helping us get our field). We then set up the field with two other teams; Team Unlimited from Sharon, and Team Weather from Stow. Once the field was setup, it took us another good hour to get the samantha module’s up and running with our router (we’ll post a tutorial about the module at the end of the season for next year rookie teams).


Omni-bot 2.0

Once we got the modules up and running, we were finally able to have a “scrimmage” for the first time! It’s pretty invigorating trying to control a robot while there are two other robots driving around a 12’x12′ field. After some time of playing around with the wireless driving, we finally decided to actually test our robot out. We were able to easily balance on the bridge, even with another robot, and we were actually able to get batons out of the dispenser without our alignment program running! We were also able to dispence the batons into the flat goals, and we are very close to dispencing into the rolling goals. During our next meeting we’re going to work on a autonomous program that will be able to dispense from any goal, and a program that will find the goals for us during the driven period to make sure that we are aligned properly. There will hopefully be videos posted on our youtube channel tomorrow after our meeting showing how our programs work for the alignment. Good luck building!
T-minus 2 weeks!

 Today in FTC Robotics we split into groups. I was in Israel for the first three months of the school year and have just joined the team this week. It is very exciting but I have a lot to learn. Today I was brainstorming ideas for our logo but hopefully soon I will have learned enough to significatly contribute to things that have more to do with the robot itself. Today for the first time, we got to use a computer that our school is lending us. We had fun programming some of our fingerprints into the computer as a way to login. Some people spent more time playing around with and getting comfortable driving the robot. I saw that someone had also built batons and a baton holder that we can use to test out the robot as it is constructed to complete more tasks. It has been a bit difficult with our coach in Israel. We communicate each class via skype which is helpful. We still have lots to do and are pretty good at getting it done. But still, it is harder to get instructions and advice through a computer than through a person. Everyone has been great in helping to get me caught up. When I know more about how everything works then I will be able to explain more of what other people were working on. I know that Chaney spent the class getting more comfortable with programming.
