Build Session 1: The Perimeter

Done perimeter

Yeah!!! :)

This was our first build session for the season! Some of the people on the team hadn’t used a saw before, and some hadn’t even used a drill. We spent the first hour learning how to use the tools that we had, then we dived into putting together the outer perimeter of our field. We started by working on cutting more then 40 pieces of PVC piping into sections for each 4’ piece of the outer walls. We ended up taking more then 2 hours to build the first two walls, but that was due the the fact the we needed to learn how to use the tools. After taking a small break, we went back to work finishing up the walls. We started to measure the finished product and realized in was shorter then 12’x12’. We flipped out. We then found out that the field dimensions aren’t exactly 12’x12’, and that they are supposed to be smaller then that. We finally finished after 4.5 hours of working, with and amazing product. We are hoping to get the kit this week and start putting the robot together with some programs to test it out.

New parts!

Nathan Parts

Smile for new parts

We just received our new parts in the mail! We got a gyroscopic sensor, a magnetic sensor, and some new hardware. The motor controllers are out of stock! It’s not a good time for something to be out of stock….During the scrimmage over last weekend, Ben was able to program the gyro sensor to measure the angle from the calibration use a lot of intricate equations (the gyro sensor puts out degrees/second). It took him a while, but he figured it out, and it works really well. He tested the gyro by making a program for the robot so that we could control it by tilting the gyro sensor. We are working on more designs for the baton dispenser and holder, but we don’t have the parts to prototype them. While Ben was working on the gyro program, the other Ben was working on a joystick control program that worked really well. On the hardware side, we just order a load of parts, although the motor controller and resource kit are still out of stock, which gives us a lot of complications. We hope to have the prototype for the base of our robot done by December 1st.

First scrimmage in Connecticut

Scrimmage robot

Big scary robot....

Wooh. Big robots. We just had our first scrimmage today, and we had a look at our first robots that we would be competing against. Our first reaction was, wooh, those robots are big and complex. Our current test robot could only go up in the bridge, thats it. We don’t even have any extra parts yet! The table to the right of us had a robot that looked complete. It was slightly intimidating. After we got over our inital shock, we started to look around at other designs for robots. We saw mostly 6 wheel, or 4 wheel drive robots, and we saw one omni-directional robot (which made us feel way better about our design). We also saw a few methods for how to get the batons out of the dispenser, though we didn’t see that many that worked…. There were many designs, and I think that it’s pretty awesome. So….to all FTC teams out there, keep on building!! Good luck guys, everyone is cheering for you.

Drive, drive, drive

First robot

We had our first working robot, but now we are starting to work on some prototypes for the arm and the baton holder. We worked on some light following techniques, and ultra-sonic tracking and driving. Nathan is currently working on the “arm” (or the baton-dispenser) for our robot, and I (Sam) am currently working on a design for the baton-holder to be lifted and turned to drop the batons out of our holder. Ben(x2) are working on the lint following techniques and ultra-sonic tracking, and they’ve made it pretty far. They have been able to track a person, follow a line, and do both simultaneously. Aaron is currently working on baton holder 2.0 built out of lexan.
