Roland Pelayo has written up his project in which he creates a hexapod walking robot with a Raspberry Pi for control. He’s used a piece of acrylic as the main chassis and then fashioned legs out of strips of aluminium. The servos are powered by AA batteries whilst the Pi is powered by a 5V “lipstick” power bank. He’s added an ultrasonic distance sensor for autonomous operation. The software is Python on the back end and he’s also created a PHP/Javascript front end to operate it manually. A write-up of the project is available here, the code is available from GitHub and you can see a video of it in action below:
