I just wanted to hear what people used for their drive trains including:
Team #?
# of years of participation?
# and type of motors?
# and type of drive wheels?
# and type of non-drive wheels?
Transfer system(chains, belts, etc.)?
Transmission (not including supplied ones)?
Steering?
Sensors?
Success?
Problems?
Next year?

• 1072 (go hrt!!! )
• rookie team
• 2x Drills
• 4x skyway wheels with traction material epoxied on (back wheels were effective on the carpet/ramp, front wheels were effective on the HDPE)
• no non-drive wheels
• chain drive for both front and back, motors mounted vertically using helical gear set
• bosch transmission and supplied helical gear sets
• tank-steering. the bot would skid on the wheels not suited for the material it was on (if it was on the ramp/carpet, the front would skid, if it was on the hdpe, the back would skid)
• 3 banner sensors mounted on bottom for line-following, though we didn't end up following the line
• the drivetrain worked pretty well.
• The traction material fell off the wheels alot, and we had some wiring issues with the motors. our transmission broke once, but it was easy to fix. our servo-powered gearshifters never made it onto the bot. there wasn't enough torque to move the little switch on the bosch transmission.
• don't know about next year. We stayed away from more advanced systems like omniwheels and crab drives cause we were a rookie team, but we might just be more ambitious next year
