This ball caster uses a 1″ diameter plastic ball and has an overall height of 1.1″ (29 mm). The two-part housing snaps together to securely enclose the ball and three plastic rollers that reduce the friction between the ball and the ABS housing. The base piece of the housing has holes for three #4 or M3 screws (not included).

This light ball caster uses a 3/4" diameter plastic ball. The height of the assembled kit ranges from 0.9" to 1.2". Dowel pins are used to minimize the friction between the ball and the ABS housing.

With this accessory kit, you can convert your balancing Balboa chassis into a traditional differential-drive platform with a low-friction ball caster providing a stabilizing third point of contact. The included ball caster pieces are held in place by a removable retention clip, and the whole assembly conveniently snaps onto the front/top edge of the Balboa chassis. This kit is also useful in balancing applications, where the ball caster can be left off and the extension piece can be used to make the Balboa taller and give it more mounting points. The parts for this kit are already included in the Balboa Chassis with Stability Conversion Kit.

2 6mm ID x 12mm OD 1612 Series Linear Ball Bearing (35mm Length)

This kit gives you the structural pieces you need to build your own Balboa chassis with stability conversion. The chassis includes an integrated battery holder that can be configured for 4 or 6 AA cells. Two configurable gearboxes further increase the gear ratio from the required micro metal gearmotors while supporting the weight of the robot with ball bearings rather than the gearmotor shafts themselves. The chassis works with a variety of wheel sizes and micro metal gearmotors, so wheels and motors are not included; choose your own wheels and motors to personalize your robot.
