...where a bunch of geeks got together to make other people's ideas come to life.
This set contains components that are great for adding a tracked drive system to a small robot or vehicle. The flexible one-piece silicone tracks are available in two lengths, with either 22 teeth or 30 teeth that are designed to mesh with the drive and idler sprockets. The 22T set, with an overall length under 90 mm, is short enough to be used as the drive system for a mini-sumo robot.
The drive sprockets are designed to press-fit securely on the output shafts of our micro metal gearmotors and 15.5D mm metal gearmotors. These gearmotors are intended to be mounted onto the side of the hub with the protruding teeth. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.
The output shafts on the Solarbotics metal gear motors will also fit these sprockets, but because they are shorter they will have to be mounted onto the other side of the sprocket where the fit is tighter. These sprockets will also work in this orientation on Pololu plastic gearmotors with 3mm D-shaft outputs. Includes:
