Physician Who ultimately made mild of the truth that the Daleks had been critically impaired when it got here to staircases. This rover from [WildWillyRobots] doesn’t share that challenge, because of a sensible suspension design.

The rover itself is constructed utilizing 3D printed parts for every part from the enclosure, to the suspension system, in addition to the wheels themselves. It makes use of a rocker-bogie design, which NASA designed for Mars-bound rovers and we regularly see copied for terrestrial functions. Gear motors are used for his or her plentiful torque, and they’re positioned straight inside the wheels. Servos enable the person wheels to be steered, permitting the rover to crab sideways and carry out zero-radius turns.

The rocker-bogie setup does an awesome job of maintaining the rover’s wheels touching the bottom, even over tough terrain. It readily tackles a random pile of bricks with ease, in a approach that many four-wheeled designs would wrestle to match. Given its trials on Mars, it’s straightforward to name the rocker-bogie setup a thoroughly-proven design.

We’ve featured loads of different rocker-bogie builds up to now; lots of them are 3D printed as properly.
