Description: This is the Multi-Chassis Tank Kit, an easy to assemble and use robot chassis platform. The Multi-Chassis kit provides you with everything you need to give your robot a rugged tank tread platform with plenty of room for expansion to add various sensors and controllers. All you need to do is supply is a basic motor driver and power and you’ll be ready to drive!
This Multi-Chassis Tank Kit includes two 48:1 DC gearboxes with a metal final output gear and shaft that independently drive each 52mm tank treads making this chassis able to drive around tough terrain like tall grass and sand. Each side of the 2.5mm thick aluminum frame comes cut with plenty of attachment points to add a multitude of different robot controllers, drivers, and sensors. A standard size servo can be mounted inside the chassis and be used for robotic arms or sensor arrays.
Note: A building instruction booklet with a complete list of items included is inside this kit and in the documents section below. This comes as a kit but includes all the hardware and tools necessary for assembly.

While the metal chassis is solid and versatile and the wheels are intelligently mounted with proper bearings, the included battery supply is next to useless. It will barely even spin the wheels with five fresh alkalines fitted - unless the tracks are removed. It certainly won’t drive the vehicle and that’s with no extra weight other than an Arduino! The tracks seems to be far thicker than is needed in this application and introduce substantial friction. I would have been much better off buying two Ardumotos and instead choosing the 4WD wheeled version of this chassis, I now need to go to the hobby store and see what is available in larger battery packs. Maybe linked tracks with less friction would be an improvement?
Update - I bought a 2S LiPo battery pack. With this battery (nominal 7.4V full charge) this chassis has all the performance I want. It seems the 5 x AA (nominal 7.5V full charge) battery holder included with this chassis is simply garbage - throw it away. Easiest explanation for its poor performance is that the cell connections are high resistance because the tight plastic molding does not allow the weak springs to push the battery against those poorly shaped terminals with any force. In fact I got zero voltage initially, had to assist the springs to get the cells to make contact! How dumb is it to skimp on a battery holder when it makes your whole product look useless?
Five double A batteries do not provide nearly enough power for this tank. Also, there is no data on the motors so it is difficult to find out how much power I can actually supply to them.
Its a solid build, and kinda a cute little tank, but I wont crawl up or over some rugs in my house. I’m not sure what do to for more power. I considered making it “4 wheel drive” but now it just sits. I had a lot of plans for this, but now i’m looking bigger.
