Re: Drivetrain, what did you use?

Team 263
- 5 years participation
- 2 CIM (atwood, chippy, chalupa, etc)
- 2 custom 10 inch dia. 7 inch wide aluminum wheels, wrapped in neoprene, very good traction
- 0 non drive wheels, 2 hdpe (teflon in the past) skids in front. currently dubbed the sled bot by SBPLI judges
- 4:1 4:1 gear reduction, then 7:5 chain reduction
- no shifting...yet
- 2 wheel rear steering, no drag in the front of the robot
- 2 sensors to tell them robot in autonomous what side of the field its on to determine what turn to make
- 100% success with the drive train, no failures and ability to push most other robots
- problems... wheels were too wide and too big (although smaller dia than our previous wheels). combiner would have helped, had one last year but deemed it unneeded only to turn around and decide it does help to have one
- next year, swerve (crab like) drive (we hope) currently working on a prototype now, if successful it will become the model for next years and the robot cart. 2 drill in front with custom gearboxes, 2 chippy in the back with custom gearboxes. experimenting with window, globe, fp, and van door to turn the wheels, not sure what works the best yet
