The first video shows the finished Mad Mech being taken for some test drives. There’s a lot of great effort that went into this build, and shows his work and process on his project page and in the videos embedded below. After a few more details and a good paint job, it was ready to roll. It was coated in fiberglass for strength, then the rest of the work was done with body filler and sanding for a smooth finish. The cardboard design was then modified to make it match the body of the Peacemaker as much as possible. used a papercraft tool called Pepakura (non-free software, but this Blender plugin is an alternative free approach) for the design to make the body out of thin cardboard. The vehicle itself uses an Arduino UNO with an L298N motor driver. Control is via a DIY wireless controller using an Arduino and NRF24L01 modules. The vehicle is remote-controlled and the tank treads are partly from a VEX robotics tank tread kit. Taking inspiration from the ‘Peacemaker’ tracked vehicle in Mad Max: Fury Road, he replicated it as the Mad Mech.
Maybe the next version could be tethered, like Scrobby the solar panel-cleaning robot. Squeak past the break to see it in action.Īs far as we can tell, will still have to break out the ladder to place GRawler and move him between panels. can control GRawler’s motors, the brush’s spin, and raise/lower the wiper blade over Bluetooth using an app called Joystick BT Commander.
GRawler also uses commonly-available things, which is always a bonus: the brush is the kind used to clean behind appliances, and the squeegee blade is from a truck-sized wiper. It’s driven by an Arduino Pro Micro and built from lightweight aluminium and many parts printed in PLA. GRawler is designed to clean on its way up the roof, and squeegee on the way back down. Now, with the addition of stepper motors and grippy tank treads, can tell this version of GRawler exactly how far to go, or to stay in one place to clean a spot that’s extra dirty. He’s tried to make a cleaning robot in the past, but the 25% slope of the roof complicates things a bit. While he enjoys the natural light and warmth, he doesn’t like getting up on a ladder to clean it every time a bird makes a deposit or the rainwater stains build up.
