A robot designed to house the Raspberry Pi Model A+ or Zero, two 28BYJ-48 Stepper Motors with ULN2003 Drivers and a hr-sc04 or hy-srf05 ultrasonic distance sensor (srf05 recommended).
Optionally the steppers and drivers can be replaced by a micro gear motor and dual h-bridge driver.
Its powered by a cheap USB power bank (the ones that hold a single 18650 battery) that sits on top.
Aside from that the only thing you will will need is 4x m3 bolts/nuts to secure the steppers and 10x dupoint cable to hook it all up.
With the zero, there’s plenty of room inside for other modules, like a compass.
The ring on the lid is sized to optionally have a neopixel ring taped under it!
