I'm trying to repair a robot vacuum cleaner, brand clatronic.
Symptoms: it only operates in reverse, while it should go forward and turn in the event the front sensors are activated.
The front bumper is pushing 3 sensors inward, which in normal operation activate a reverse motion and some turn before moving forward again.
Light sensors ?
After disassmbling and testing, I concluded that the sensors don't do anything anymore, if connected or disconnected, the motors keep spinning in reverse.
The sensor looks like this:
The outer cables have a voltage of 2.5 V, permanently powering the dark component (lower left on the picture).
The upper left component is connected with the 2 first cables, which I would suspect is the sensor making a connection.
The sensor cable:
3 of these are connected to this board:
So the quetion is simple: can this be repaired ?
