A maker has developed a way to use the programmable board Arduino to build a walking biped robot that is 3D printed with legs that feature three servos that actuate at the hip, knee and ankle for six degrees of freedom.
The Arduino Uno board rides on top of the legs handling the controls along with a perfboard to connect to the servos directly.
The maker, Technovation Projects, said the goal was to make a system that would allow a robot to walk and even run without the hardware failing. The secondary goal was to make the biped robot cost effective so that anyone with a 3D printer could build the device.
Movements of the robot are calculated via inverse kinematics and the Arduino calculates the proper servo angles. The robot can also take steps between two and 10 centimeters long without falling over.
Arduino has been used to build just about anything that can be imagined — from VR headsets, to COVID-19 masks, to lie detectors, coffee roasters, STEAM kits and everything in between.
