Its powered by the Pimoronoi Servo 2040 (there aren’t many boards that have 18 Servo sockets), and programmed in MicroPython. Inspiration and idea - Why I designed this robot I want to make a small bipedal robot for experimenting with walking and gestures. I also want to make one similar to: Plen Robosen EZ-Robot Called Chip - because it will sit on my shoulder… Chip will be made up of: 19 Servos (Yikes - will be expensive) 3D printable Powered by RP2040 based Pimoroni Servo 2040 MicroPython Detects movement and responds Capable of many gestures; Walking, Pointing,Waving, Clapping, Running, Crawling Electronics - Bill of Materials To build Chip you’ll need the following parts: Part Description Qty Cost Servo DS 929MG Servos 19 £9.90 Servo Driver Pimoroni Servo 2040 1 £20.00 Range Finder HC-SR04 Range Finder 1 £6.00 Battery pack TBC 1 £0.00 3D Design - Fusion 360 Here are all the 3d printable parts that make up Chip Part Description Houses the Arm, Leg and Neck Servos, M2 Screw holes for servos, 4x M3 for the Torso cover Protects Servos, Screws in with 4x M2 screws, Belly button Connects to Arm Servo on Torso, Connects to Arm Assembly Connects to Arm Servo on Torso, Holds two servos Connects to Arm Servo on Torso, Holds two servos, Connects to Hand Connects to Arm Servo, The sound of one hand clapping Connects to Leg Servo on Torso Holds two servos at 90 degrees from each other, Pivots in 2 DOF, No top cover required as the servos connect to the respective servo pivots on the attached pieces, These are used in the upper and lower leg Hinge with Servo at 90 degrees Connects lower leg to Foot Connects Shin to foot, Holds 2x Servos Completes the Leg Assembly, 1 Degree of freedom 5x Servos per leg, 6 degrees of freedom including the Hip servo 18 Servos for the full body, Hands can touch, Legs can sit, crawl, stand, walk Holds the Ultrasonic Range Finder Sensor, Attaches to Neck servo Head contains a Range finder, Head can turn 180 Degrees left to Right Future plans I’ve a couple of plans for Chip - Walking Cycle with IMU for Balance Fun Animations & Behaviours MicroPython Library for Chip Course on KevsRobots.com on how to build Download the 3D printable STL files The files will be released once I’ve confirmed the parts all fit correctly - they are still a work in progress.
