2015 Build Season Update: Week 6 Activities

Rockford Robotics attended a “Week Zero” scrimmage in Planefield, IL on February 14. The event was less a competition than a large public demonstration/practice. There was a half-field with ample game pieces. Three teams were allowed out on the field at once and could run their robots for around 5 minutes or so. With only a few teams participating, there was plenty of field time for everyone.

The scrimmage was a great opportunity to learn about our robot’ strengths and weaknesses. We discovered a few issues with our robot. Some we could fix immediately and others for which we plan improvements. Our robot was able to drive, operate the lift, and pick up and stack totes. We also developed a new possible strategy using the tote chute.

We struggled with issues with our articulating forks, especially with wires jamming and becoming mangled. And a programming issue made it so that the forks would start closing and continue closing regardless of driver command. Finally, thanks to an extended and detailed debugging session with members from 3061 Huskie Robotics, we determined we had damaged a Talon SRX motor controller.

We made a few modifications at the event. We put a hole in one of the fork bearing plates to allow us to run wires through it. We added some shim washers to tilt our forks upward slightly to keep the totes from sliding out. When that induced additional stress into our fork motor gear meshing, we added shim washers. We added (temporarily) green duct tape to our forks to give them more grip. We will continue to improve on these fixes during the remaining week of build season.

Also at the scrimmage, Scouting Captain Aaron participated in a meeting, organized by Gear It Forward, pertaining to the development of an Android app for FRC scouting for this year’s game.
