“Bipeds are really cool because they are by far the most recognizable kind of robot. Companies have spent decades and millions to make these things. I’ve been wanting to make a bipedal bot for sometime now but most of them need a lot of motors and are pretty expensive to make. I managed to make a simple bipedal robot at home out of essentially four micro servo motors (which are pretty cheap), an arduino and a breadboard. The bot can walk, kick, dance, navigate slopes etc. Moreover since it’s an arduino you can always add sensors or other body parts pretty easily and experiment with the bot.”
