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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
