For decades, astronauts in orbit had to be tied to their spacecraft when stepping outside. In 1984, Bruce McCandless performed the first untethered spacewalk using a Manned Maneuvering Unit—a handheld device that shoots out nitrogen gas for propulsion.
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.
