Bravo Bare-Bones Chassis Kit (No Tread, No Motors, No Controller, No Battery)

SKU: Build System: goBILDA

The Bravo Chassis Kit is available in three different formats. The Rubber Tread and Paddle Grousers versions include everything you need to get up-and-running right away with heavy-duty 20V tank track action! They’re a perfect way for anyone to begin their robotics journey at a rolling start into the endless possibilities of the goBILDA® build system.

However, if you’re a seasoned roboticist, you might already have your own radio control system, as well as a 20V DEWALT® form factor battery that’s been waiting for the perfect project. You might also have ideas for tank tracks that go beyond one single kind of tread.

If any of those are the case, the Bravo Bare-Bones Chassis Kit is for you! With this sturdy skeleton in hand, you’ll need to make sure you have a suitable control system (such as that of the 20V Control Bundle) before loading up on your choice of Saturn Planetary Gear Motors and finding your ideal combination of tracks to get everything you need to build your own personalized Bravo Chassis!

Types of Terrain

The tank tracks compatible with this kit have proficiencies in different environments. Choose what kind of terrain you want to conquer, and roll out with the tank tracks of your preference!


Rubber Treads

Grouser Paddles




Smooth Flooring



Soil & Grass



Loose Soil & Gravel



Tall Grass






Need to Tread Lightly?

Consider using Grid-Tracks for use on carpet, manicured lawns, and other delicate terrains you don’t want to disturb. Grid-Tracks have a much less aggressive footprint, and are a great option for heavier payloads—their smooth surface allows the motors to pull less current when they initiate turns.
