New Robot!

Originally uploaded by Samuel R.

Our new robot is coming along well. The design for the arm isn’t working to well, but by watching a video of the robot frame by frame, we were able to see what was wrong with out arm. Since we live a a 3D world, the batons were using the treads as a fulcrum in the Z axis to tilt and fall off of the arm. We only assumed that the batons would tilt in the Y axis (using our paddle as the fulcrum), but we were wrong. This is something that we will fix very soon, and we will upload a video with the fix.
On another note, our team was invited to First Night in Boston on December 31st. We’re hoping to have a robot done by then, since our competition is coming up very soon. Vacation will help us a lot, giving us a lot of time to work. Check out our youtube channel over the next two weeks when our robot will hopefully be finished!

Parents helping out

Originally uploaded by Samuel R.

Just wanted to give a shoot out to our parents that helped to finish the board by painting it, while we worked on our robot. They finished up the board for a scrimmage that we are hoping to have in the future (maybe after vacation??) once we finish our own robot. Which…by the way…is coming along really well :). Check out the post before this to see our robot working!

Robot v1.5 driving

Originally uploaded by Samuel R.

Yah! The prototype for our final robot is done, and ready to be tested over break. The robot can now drive and it can also pick up batons, and drop batons, but it can’t drive with the batons. This is going to be built later once the arm is finalized. We are also working on driving around, and we found that with the gyro turned on the robot is able to get over the bridge, and without the gyro turned on the robot can’t get on the bridge. We one other omni bot the was having an issue getting over the bridge, because when one wheel is on the bridge, the other wheel “vectors” wont move the robot properly and the human driver can’t compensate fast enough to make the other wheels spin faster. Our program compensates for the robot spinning when it hits the bridge, so that the human driver doesn’t have to think about trying to get on the bridge or the cliff. The arm works amazingly at getting the batons out of the dispenser, but we need to work on the chute to drop the batons into the rolling goal. We have some good designs, we just need to construct them. Hopefully we will have our arm done by the end of this week!

Science museum robot

Mars simulation robot

A few days ago we hit the science museum. Out coach, Tal, acutally works there in the computer place! So, on Sunday, we woke up extra early to make our way down to Cambridge to see what we cpuld find in the Computer Place. We got to see the MARC bot 2, and got to play around with the Aibo dogs. We also learned how the drive train worked on both robots, although the MARC bot’s drive trin was a little more helpful for our FTC robot. Speaking of which…..our base is finished! We just finished it this week when a new shipment of parts came in. We also got the parts for a baton dispenser/holder, and that should be put together as soon as I finish the SolidWorks model. I currently only have videos of our robot, but I will post in the code section our code for the gyro sensor, and our vector equations for the robot. But until then, happy building!
