The Bravo RC Tank Track Chassis is a heavy-duty tank-track robotics platform that’s remote-controllable and ready to run right after assembly! In other words: whether you’re a seasoned roboticist looking for a heavy-duty chassis, or you’re just starting to explore an exciting new hobby, you need look no further. This plug-and-play kit is a perfect way to begin a robotics journey with the Sheen Robotics® build system!

This version of the Bravo RC Tank Chassis features grouser paddles to engage with loose terrain. There are two other variants: one sporting rubber treads, and another providing only the "bare-bones" chassis without electronics, motors, or tracks.

Titanic 20V Action

The Bravo RC Tank Track Chassis Kit’s heavy-duty action is made possible by a full suite of 20V electronics (the complete 20V Control Bundle), including the Sheen Robotics® Smart Dock: a battery-protecting power solution that allows you to power your Bravo with any battery with the 20V DEWALT® form factor.

But there’s no need to plunder your power tools to complete your Bravo. This kit provides all the high-power 20V juice you need right out of the box via a 6Ah Sheen Robotics® Li-ion battery–one that rocks an LCD showing you just how much you have left before you need to recharge it on the included charger.

Your Smart-Docked battery sends power, via an XT90 extension, to the 2x40A Motor Controller which proportionally controls a pair of Saturn Planetary Gear Motors. These mighty motors are veritable powerhouses of torque that boast all-steel gears and positive-drive 8mm REX shafts!

TWO RATIOS AVAILABLE

Each version of this chassis has Saturn Planetary Gear Motors of a specific ratio, each offering different payload and speed specs. The 99.5:1 ratio motors of the higher torque version (SKU: 3209-0008-0003) allow for a whopping 50lbs of maximum payload at 2mph, while the 50.9:1 ratio motors of the higher speed version (SKU: 3209-0008-0002) provide for 25lbs of maximum payload at a 4mph clip.

Pick-up-and-Play Remote Control

The tried-and-true Element-6 control system uses built-in channel mixing to allow for intuitive, on-the-fly remote control. The rightmost stick provides proportional control over the speed and direction of your chassis. Thanks to the stick’s spring-returns, all you need to do to stop the chassis is release the stick. Meanwhile, the left stick, a knob, and a switch all provide control of servos and other devices when you build on your chassis to make it perform specific tasks.

Terrain-Conquering Tracks

A combination of Grid-Tracks and terraGROUSER paddles give this Bravo Chassis amazing traction on loose terrain. While the assembly instructions depict the installation of a grouser paddle on every other Grid-Track, you can choose whatever spacing you prefer for whatever environment you'll be using your Bravo Chassis in!
