Mini Rover

 
 

This is my smallest robot 20x20cm and 9cm hight. 
You can control it via WIFI like the other robots but this also has 8 HC-SR04 distance sensors.
The distance will show on the screen (larger red semicircles means the object is closer).
I thought also to use a 4 Channel Infrared Obstacle Avoidance Sensor to detect if a edge is close to the car but that did not work so well. Depending on how reflective the surface was it gave false signals...

Just drive around on the floor...

Drive around in our house with my Mini Robot Rover.
Find exciting things like cats and dust bunnies :-)
