Re: What drivetrain did you do?
 

Soap-Box style steering X 2.

Two pivoting axles, linked with a cross-bar to provide high-speed staight-away and turning. Each axle has a pair of CIM motors, driving inline 3:1 Banebots Planetary gearboxes and custom made 4" diameter traction wheels.

Original tests showed that we could drive and steer JUST using differential speeds on the opposing wheels, but we ended up adding a dedicated steering motor with position feedback for Hybrid mode.

Re: What drivetrain did you do?
 

we invented our own drive system! (you may of seen videos of it on other threads) It called "the Linkage" and it is 4 omnis set up like 4wd, that switch 90 degrees so they are also 4wd in a sideways orientation, giving us 4 motors of power in all 4 directions without the mechanical no how of a swerve drive!

We did a true Ackermann type steering, with a ATV differential in the back, powered by 4 CIMS running through a modified AM 2 Speed Transmission.

6-WD. Omni's on the front, 2007 kit wheels in the middle and back. Two CIM's per side. Zero drop on center wheels. One speed at 10 fps. Stable & strong. Easy to turn, but doesn't spin out on fast corners.

we are driving a 4wd using super shifter with performance wheels in the front and a kit wheel back right and an omni on the left. turns slowly in low but takes the corner perfectly in high gear.
