Description: This is the Multi-Chassis ATV 4WD 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 four wheel drive 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 Basic 4WD Kit includes four 48:1 DC gearboxes that independently drive each of the 78mm high-profile wheels. The larger wheels give you clearance for driving through more difficult terrain like grass or sand. The gearboxes have a metal output shaft for more durability. 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.
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.

Even when running the motors at ~4.2v (across the terminals), which is above the recommended 3v (from the datasheet), the motors seem to have a very hard time pushing the heavy chassis around at anything more than a crawl and stalls out at the smallest of obstacles.
EDIT: Unless the datasheet is wrong and I should be running these closer to 6v or even 9v – but I don’t want to burn out the motor testing that out.
Very nice and solid construction
This robot chassis is great for building your next robot. Because it has 4 motors, this is not a chassis for the beginner. The aluminum frame provides a low center of gravity making the robot stable and not easy to turn over. There are plenty of attachment points so you have plenty of configuration options and devices. There are two areas that could make this chassis even better; a wider frame and option to configure the chassis with only two motors. A wider frame will provide additional area for sensors. Lastly, adding an option to configure/drive the chassis with only 2 motors will provide a beginner with a platform that can learn robotic now and can continue to expand as he/she gains knowledge.
