Badland Brawler Lets Arduino Tackle Terrain

For an electronics person, building the mechanics of a robot — especially a robust robot — can be somewhat daunting. [Jithin] started with an off-the-shelf 4 wheel drive chassis to build an off-road Arduino robot he calls the Badland Brawler. The kit was a bit over $100, but as you can see in the video below, it is pretty substantial, with an enclosed frame and large mud tires.

The remaining parts include an Arduino, a battery, and a motor driver IC. The Arduino is one with WiFi (an MKR 1000, in fact) and there’s a phone app for controlling the robot.

Honestly, once you have the chassis taken care of, the rest is pretty easy. Of course, the phone app is a bit more effort, but you could replace it in a number of ways. Blynk, comes to mind, for example.

The motor drivers are easy to figure out. This would be a great platform for some sensors to allow for more autonomy. We liked how the frame had mount points for a lot of different boards and sensors and could hold everything, for the most part, inside. That’s probably a good idea for a robot which will be traversing rugged terrain.

If you do decide to roll your own app with Blynk, we’ve done it with a very different kind of robot. Four-wheel drive robots don’t have to be big, as we’ve seen in the past.

XBee-controlled 4WD wireless robot

In his blog, Michael describes a nice 4WD robot he realized by means of an arduino-compatible board, a motor shield and a couple of XBee radios, which have been used to implement a simple and effective remote control.

Actually, the remote is made up of a standard breadboard equipped with a joystick, a couple of buttons (that can turn the robot in a Kitt-like vehicle!) and the XBee radio. One interesting feature of this project is that the remote controller is fairly simple and has been designed to work with just the XBee radio board, instead of requiring an additional MCU.

Drives Arround

I started this robot a couple of weeks ago, it's just plywood, plastic wheels, some hitec 615mg servos that were laying around modified for continous rotation.  Currently control is through an Arduino Uno being fed by an RC receiver.  I have a PING sensor and some IR LED's that I think might make it a bit more interesting in the near future. The code is really ugly at the moment.  I'll attach it to this post as soon as I figure out some place to stick it.
