Make this 3D printed crab controller and crab simulator using Arduino Mega. via instructables
A 3D-printed, posable crab input joystick for controlling tetrapod walkers, motion capture, and simulations. With 4 legs and 3 degrees of freedom per leg, the Crab Controller sends data through an Arduino Mega via the Standard Firmata protocol to another device. Here, the crab controller is being used to control an underwater virtual crab simulator in real time. This project is expected to cost around 60-80 USD and 1 week for assembly.
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.
