What is SMARS Mini

SMARS Mini is smaller version of the original SMARS Robot. It is 1/10 the size of the original, barely wide enough to house the two N20 Motors.

Tiny Electronics

SMARS Mini is so small it needs to have special, tiny electronics, to fit in the chassis. These include the VL53L0X Time of Flight sensor, that uses a tiny laser to sense objecst up to two meters away. These are just as cheap as the original sensor but much, much smaller.
