I was curious about the motors. Are those 4 pole motors that are being used? In any event, that's great mph you have pushed out of them considering the load. Please keep us informed regarding the contest and best of luck. Thanks for insights Nicholas. I was curious about the motors. Are those 4 pole motors that are being used?

We have found that the wheelchair frame and motor system are incredibly robust and reliable. We have been very pleased with the system. We decided to put tracks on the robot because the swivel wheels caused the robot to veer off course on hills. The tracks allow the stability and power of a 4x4 system while maintaining a great turning radius. The motors are so powerful that the robot still has a top speed of about 6 mph even with the added load of the tracks. The onboard computer interfaces with the motor controller of the wheelchair. We created a small add-in circuit board that receives commands from the serial port of the computer and then emulates the output of a standard wheelchair joystick. The IGVC competition is coming up in less than a week and we are confident that Y-Clops will be very competitive! I’m glad you found our project!
