Description

A much smaller version of the popular Spotmicro robot.

Details

The goal was to design and build a smaller Spotmicro robot. The Spotmicro was originally created by Deok-yeon Kim (KDY0523 on Thingiverse). The SpotPico is a much smaller version of that robot. It uses smaller and lighter 5g servos and is controlled by a TinyPICO NANO.

Final design

The final update design has been partially assembled and a USB C connector had been used in place of the micro USB connector.

The tiny 0.49" OLED display has also been fitted and all wiring has been done.

Will be powering up the TinyPICO NANO next to make sure everything functions as it should
