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 goBILDA® 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 goBILDA® 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 goBILDA® 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!

Types of Terrain

This style of the Bravo Chassis Kit features grouser paddles, while the other Bravo variant sports rubber treads. The two track types have proficiencies in different environments. Choose what kind of terrain you want to conquer, and roll out with the Bravo chassis of your preference!

Need to Tread Lightly?

While grouser paddles offer awesome terrain-conquering capacities, using them in your final assembly is completely optional! Grouser-less Grid-Tracks are ideal for use on carpet, manicured lawns, and other delicate terrains you don’t want to disturb. Their gentle footprint also means they’re ideal for heavier payloads—their smooth surface allows the motors to pull less current when they initiate turns.

Want Even More Options?

You can purchase a Bravo Bare-Bones Chassis Kit along with Grid-Tracks and/or Badlands Tank Tracks, a 20V Control Bundle, and Saturn Planetary Gear Motors to get all the options you need to outfit your chassis exactly to your liking!

WARNING: Stalling the motors in this kit may cause irreparable damage!The motors included in this kit are extremely high-power. DO NOT allow the motors to stall. Stalling can occur if the motors run when the maximum payload is exceeded or the chassis is immobilized by obstacles.
