i have a problem with my pool robot.
mechanically everything works fine ( the 2wheels spin ) yet this year the robot got "stupid"
it just block himself somewhere and stops.
i belive either a sensor is dead or the program got stupid for some reason....
It is out of warranty so nothing to loose here.
The robot is a Zodiac vortex 3. I belive there is only 2 motor for the wheels, 1 motor for water absorption always on. and a sensor to tell the robot when he is out of the water.
First question, do you think the card controlling the robot is inside the robot or on the home?
There is this 2 pin might be for one motor, one for the 0 and one for the sensor.
unfortunately i belive the card is in the robot.
Other question is if the motor are direct current or stepper. I saw a post where someone says it s stepper which will complicate things...
Anyway my goal is to have a arduino controlling some relay activating the motor from outside the water.
