About a month ago we have seen those quick and funny solderless robots with no brain that moved only in one direction. Well, this time someone got an idea of smartening them up.
Two vibration motors are mounted on two tooth brush heads and they are controlled with Attiny13 microcontroller. Sensible motor control is accomplished by using a sensor from an optical mouse. Used sensor is ADNS5020 but author notes that it is possible to use other similar sensors. Source code for Attiny13 is written in C and it is available for download. This is very good part of the whole thing, because in it we can find routines for communicating with mentioned optical sensor.
On the same web site there is another very interesting project: optical mouse cam which is actually a scanner made out of the same optical sensor.
In video below we can see that the robot stays within the circle drawn on the floor.
Ovdje stvarni ima "ludih" stvari i ideja :)
