Roboh

Three wheeled robot, rear stepper for drive, micro servo steers and directs ultrasonic sensor. Tires utilise under sink s bend replacement seals (Plumbing spares). This project utilises Arduino Nano as the processor and two 18650 batteries for the power. I have this robot running a simple search routine that gets it around many a room without getting stuck. It drives well on carpet and tiles. All files are designed to print without supports. You will need to rotate them in your slicer. PLA works well I have not used any other material for the print. I am using this robot to teach STEM: 3d printing, design and programming.

UPDATE:
V2 Lid allows the use of Nokia Screen for output of ultrasonic readings.

Instructions for building will follow....
