The LEGO Guardian #piday #raspberrypi @Raspberry_Pi

via Eduardo Oliver via hackster.io

We are going to build a robotic car that is capable of collecting the pieces of lego that are detected by vision algorithms, and will use ultrasonic sensors to give the robot more autonomy.

It would be quite different from the current solutions, because it’ll be a robot that will literally go looking for the pieces of LEGO, and will pick them up so that its owner will not be harmed by them.

The robot is based around a car-rover, the Spresense development board will control the engines through a DC motor driver. A sweeper will be used to collect the pieces of lego, this will be made in turn with three servos and 3D printed parts (or laser cutted). To control the car, we will use ultrasonic sensors to prevent the car from crashing into walls or obstacles.
