Description:

We machine it to a custom length. Using two of these you can make your custom sized robot. Two motor adaptor plates are provided with hardware to mount either IG32 or IG42 inline planetary gear motors to the chassis side.

This kit can support multiple types of wheels which are listed below

• ATR Wheel Shaft Set Pair 6mm Bore - 6 inch
• ATR Wheel Shaft Set Pair 8mm Bore - 6 inch
• ATR Wheel and Shaft Set Pair 8mm bore - 10 inch pneumatic
• Omni-Wheel and Shaft Set - Double Row
• Omni-Wheel and Shaft Set - Double Row
• Nexus Omni-Wheel and Shaft Set - Double Row

These are not intended for our right angle gear motors, different adaptor plates would be needed.

Features and Specifications:

• 2" x 2" Aluminum tube with a 1/8" thick wall.

The width of robot is up to you, it must be at least (the length the gear motors + 2" tube + 1/8" adaptor plate) x 2. A simple piece of plywood, aluminum, or acrylic can be used to tie the two side together or the sides can be bolted onto your own robot chassis.

The tube structure uses the bearings in the above linked wheel kits to support the axle. The other side of the axle is supported by the motor. This provides a much stronger attachment for the wheels and the load is put on a heavy duty bearings and tube instead the motor. Direct coupling a wheel to the motor will just ruin a motor quickly. Below are pictures of some assemblies using the sides and wheels.

Available Options:

Below you can specify the center to center length of the side. This will be the distance from one bearing/axle to the next. Specify the center to center length of the axles in inches. Total length of side will be an additional 3 inches. (i.e. there is 1.5" of tube past each axle center. The maximum center to center is 32.5 inches, the minimum is 8 inches. The motor coupling can be selected for either an IG32 or IG42 and must be selected below.
