Description:

This is a base kit for a robot that you control the size of. Specify the length as explained below and build it to your desired width as explained below. This kit gives you all the options for a base robot kit. By default this is sold without the motor controller, batteries and electronics. They can be selected using the options below.

The kit includes custom sides that are 2" x 2" Aluminum tube with a 1/8" thick wall. We machine it to a custom length. Using two of these you can make your custom sized robot. 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 sides together or the sides can be bolted onto your own robot chassis.

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 - Single Row

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.

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. All other options are included below as a menu to build your custom robot. With the batteries, we do not recommend the 2200mAhr batteries unless its real light duty with IG32 gear motors.
