Two quick and recent videos from the BuildIts blog showing Ben Katz’s progress with a robotic leg design, showing extensible action and response time from keyboard commands. You can see they have pretty good ‘thrust’ and from an appropriate surface could probably ‘jump’ quite high. Fun!
I milled out a simple 4-bar linkage leg. Leg dimensions were roughly taken from the SMC robot. It’s really fun to prod at with different joint parameters. Each motor controller takes joint position, stiffness, and damping commands in over SPI
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
