Description: This is the Multi-Chassis Rescue Platform, an easy to assemble and use robot chassis kit. The Multi-Chassis kit provides you with everything you need to give your robot a unique tank tread platform with plenty of room for expansion to add various sensors and controllers. What separates this Multi-Chassis kit from the others is that it is equipped with four tank treads, the two inner treads remain stationary while the outer two can rotate giving your robot the ability to climb low ledges. 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 and wheel encoders that independently drive each inner 52mm tank treads making this chassis able to drive around tough terrain and climb small steps. The outer tank treads are controlled by a S06NF STD 60° servo which allows the treads to rotate to whatever angle you need them to be in. Each side of the 2.5mm thick aluminum frame, that encloses each gearbox, comes cut with plenty of attachment points (multiple opportunity points) to add a multitude of different robot controllers, drivers, and sensors. The metal frame also has an internal holder available for you to add a servo to your robot to control the outer tank treads.
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.

I knew going in from other reviews that this had poor documentation so I wasn’t completely surprised but it was worse than I thought. The docs are so poor that you really need either some electronics experience or really good search skills to get this working. I’m an experienced EE but wanted to walk my son through figuring it out. It wasn’t possible to find docs with enough detail. Even searching I couldn’t find sufficient docs on the encoders and I just had to tell him how to wire them and use general hall effect sensor docs to explain it.
The worst problem is that the motor/battery pack combination is just barely adequate if it even is. So far we can’t get it to do anything except run on perfectly smooth floors when running off battery. Using an external supply at the same voltage it does better, haven’t experimented too much but it looks like we’ll need higher voltage to get any power. For the price I expected a better matched battery/motor set.
We’re using a Seeedstudio V 1.0 Motor Shield (L298N based) on an Arduino to drive the motors and full drive isn’t adequate. That shield isn’t a good match as the sensor ports aren’t compatible with the sensors from the encoders. I have a couple of high power Chinese motor drivers that we’re going to try next but they don’t mount as well.
The lack of Arduino mounting holes is also annoying but that was discussed in several posts so I knew to expect it. We attached a couple of hard rubber strips to the chassis and the Arudino to the rubber strips. We plan to switch to a Raspberry Pi once basic learning is done.
I think I’m going to end up replacing both the motors and the battery pack. I expected a kit that was usable.
