Description

Motherboard for LittleBOT.
LittleBot is a small robot equipped with a control card with an Arduino Nano. The chassis is made of aluminum and is moved by two small motor-driven motors made entirely of metal that move a pair of tracks.
The robot has some sensors that allow it to detect some parameters including brightness and temperature. A front-mounted sensor powered by a servomotor allows the robot to flicker the frontal space and measure the distance from any obstacles and thereby avoid them.
The presence of a Bluetooth module allows you to pilot the robot wirelessly via the Arduino Explorer board or via APP
