    Building an Arduino-based bipedal bot

    Arduino Team — June 21st, 2020

    If you’d like to build a walking biped robot, this 3D-printed design by Technovation looks like a fantastic place to start. Each leg features three servos that actuate it at the hip, knee, and ankle for a total of six degrees of freedom.

    Control is handled by an Arduino Uno board that rides on top of the legs, along with a perfboard to connect to the servos directly.

    Movements are calculated via inverse kinematics, meaning one simply has to input the x and z positions, and the Arduino calculates the proper servo angles. The bot is even able to take steps between two and 10 centimeters without falling over.

    ClearCrawler Strandbeeest walks under Arduino control

    Arduino Team — December 3rd, 2019

    Maker Jeremy S. Cook has been building Theo Jansen-style walkers for literally years, and after several iterations has come up with what he calls the “ClearCrawler.” 

    This little guy stands at just over 15 inches tall — including its comparatively large clear cylindrical head — and travels around via a pair of motors that move four legs on either side like tank treads.

    For control, Cook is using an Arduino Nano onboard, along with a motor driver, plus an Uno and joystick shield as the remote unit. Communication between the two is accomplished by a pair of nRF24L01+ radio modules. 

    Code for the project is available on GitHub, and the build is split up into an electronics and mechanical section in the videos below.
