Mecanum Wheel driver
This platform was built using the VEX robotics system.
VEX Parts list:
1 x Mecanum Wheel 4" (4-pack) (P/N: 276-1447)
4 x 2-Wire Motor 393 (P/N: 276-2177)
4 x Motor Controller 29 (P/N: 276-2193)
1 x Chassis Kit, Small 15x16 (P/N: 276-2024)
1 x Nut 8-32 Nylock (100-pack) (P/N: 275-1027 )
1 x Screw 8-32 x 0.250" Locking (100-pack) (P/N: 275-1002)
1 x Bearing Flat, Delrin (10-pack) (P/N: 276-1209)
1 x Drive Shaft 2" & 3" Pack (P/N: 276-2011)
1 x Shaft Collar (16-pack) (P/N: 276-2010)
1 x Tool Kit (P/N: 276-1382)
Non-VEX parts:
1 x ServoShock
1 x board for the chassis deck
2 x Female-Female servo extension wire to couple the motor controller and the ServoShock (http://www.pololu.com/product/779). Cut the connector off and jam in pins from the motor controller into the back (see pictures below).
After building the chassis as shown in the picture below, power the ServoShock board with a LiPo battery and BEC. Configure the motors as shown in the section titled Joystick Mecanum Drive Mixer of the datasheet. If any of the wheels are spinning in the opposite direction, invert the spin direction per the section titled Invert Direction of the datasheet.
