I wanted to make this project for a long time. Inspired by a projet of HowToMechatronics from a few years ago. This robot is fully 3D printed and is just the first version and is sensorless. In the future I want to add a lot more controls and sensors. This robot has 18 high torque servo motors, runs with an Arduino MEGA and is controlled by Bluetooth with commands from a smartphone. I've made a simple App to control it. See the part list, the 3D printed files, the code and all you need in this tutoprial step by step. Video Tutorial: https://www.youtube.com/watch?v=HRC5HrN8KD0 Schematic: http://electronoobs.com/eng_robotica_tut17_sch1.php Each leg needs 7 3D printed parts as you can see below. Get all STL files from this link and print the parts using PLA material. I've used a 0.4mm nozzle, 0.3mm layer height and 20% infill. We need no support and all parts are already oriented and ready for print. So, get the 7 parts for one leg.
