Full Feature THETA Robot for BBC micro:bit

by 4tronix

This is a very full-featured Robot indeed. Designed in conjunction with ROBOTIXLAB in Greece, this circular robot is delivered ready-assembled, with multiple sensors and lots of expansion capability.

Also included is a quirky 3D clip together sheet plastic cover which diffuses all the LEDs and gives the robot extra character!

Theta has its own separate microprocessor to handle all the extra features that cannot be handled directly by the Microbit. It also has standard 4 tronix extension connector so addons such as 5x5 RGB matrix, OLED screen and RoboFace can be plugged in instead of the included ultrasonic

Of course, there is a Makecode extension to make it super-easy to code all the amazing fdeatures in your favourite block coding language
