Hot Wash

It was a mixed season for Team 1740. We finished 39/41 at the Rhode Island District but, after substantial re-engineering, improved to 16/42 at Hartford. Things I observed this season:
  • We can't afford to sit around waiting for parts
  • Four-wheel tank drive did not work well with friction wheels.
  • Four by Four-inch friction wheels did not work well over uneven terrain.
  • We should spend more time investigating drive train options. (Review AndyMark presentations.)
  • All moving/mechanical systems should be controllable (forks).
  • Communication among all team members needs to happen on a daily basis.
  • All motors must have encoders.
  • We need two weeks for drive practice, autonomous testing, and PID tuning.
  • PID is the way to go, but requires sensors and adequate time for tuning.
  • Motors should be designed using physics & math, not just guesswork. (Our first climber was way overpowered.)

Off Season Plans

As part of our ongoing effort to improve, I'm reading about Scrum and plan to implement some of its principles next year. The team ordered six more swerve drive modules. We now have enough for a test bed and competition 'bot.
Fabrication
  1. Design and build a shooter of some kind just for practice.
  2. The drive and control systems on Vargas need to be replaced
  3. Figure out how to mount encoders on any motor, including the new swerve drive modules
Programming
  1. Rebuild the program for Vargas on the new control system.
  2. Design a control program for swerve drive
