Watney is a low-cost Raspberry Pi-enabled rover made of readily available parts. The majority of Watney’s parts are 3D-printable. It has a Python and a REST APIs. Watney is all-wheel drive, with each side powered by a geared motor. Because of that, it turns like a tank by spinning each side in opposite directions. It drives best on smooth surfaces, like hardwood, linoleum and tile. For carpeted surfaces, Watney can do “soft turns”, by spinning one side forward and the other alternating backwards and forwards.
The software part of Watney makes it a webcam on wheels. The camera feed is low-latency HD and rover control is accessible via a browser.
Upon startup, Watney will detect if it’s connected to a Wi-Fi hotspot. If not, it will host its own hotspot “Watney4”. Once you connect to the hotspot, you can control it directly by going to http://192.168.4.1:5000, or connect it to a Wi-Fi hotspot by going to http://192.168.4.1. For advanced Wi-Fi setup, you can ssh to 192.168.4.1 (default credentials pi / watney4) and edit wpa_supplicant.conf directly.
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.
