Red Light (“Sensor/Timing”) The red light indicates that the Cat Sensor has been activated and the Litter-Robot is going through the seven minute count-down before starting the cleaning cycle. Yellow Light (“Cycling/In Use”) The Litter-Robot is cycling (Cleaning cycle, Fill cycle, or Empty cycle). Green Light (“OK/Waiting”) This light indicates that the unit is OK and that the Litter-Robot is ready for your cat. This cycle is convenient for removing the old litter prior to cleaning the interior of the Globe. “Empty” Button The “Empty” cycle removes most litter from the Globe, bypassing the sifting screen. (Personally I never use this and add liter by the front hole) This position is convenient for filling the Litter-Robot with litter. “Fill” Button Pressing the “Fill” button on the Control Panel starts a counter-clockwise rotation of the Globe to bring the waste ports to the top. If you stopped the Globe during the cleaning cycle, pressing “Fill” or “Empty” will return the Globe to the home position. Press “Cycle” once again to resume the cleaning cycle. To stop the cycle, press any button on the Control Panel. “Cycle” Button Pressing the “Cycle” button starts the Litter-Robot cleaning cycle. The front panel contains 3 buttons and 3 LED. The “bipolar hall sensor” is in fact composed of 2 hall sensor assembled together in inverted position, I assume they are plugged in digital way so one pull up when in front of the corresponding magnet (with my tests on week10, when using a hall sensor in analog, with only one I can detect both north and south pole). One for the dump position, one for the home position. To find where is the globe, there is 2 magnets molded in the plastic of the globe. Then globe rotate CW (clockwise) go back to initial position. At the end of the first rotation, all the rest that not pass through sieve fall in the dump tray. When the globe rotate CCW (counterclockwise), all inside rotate with obviously (nooo, not the cat) and the sieve separates clean litter from waste solid. The main function is to rotate the globe on the base : the cat enter in the litter, he does what he have to do (or not if he’s just curious ^^), after a few minute, the globe turn and come back to it’s initial position.īy rotating, litter robot separate the clean and used litter and eject used litter in the dump tray.įirst, we have to use clumping cat litter. lower part : the base (include the control panel and dump tray). #Litter robot red timing light manual#
I made the reverse engineering by unmounting the liter, reading the user manual and finding patents. I will create a new electronic board, a new control panel and had some fun/useful stuffs like online alerting when waste drawer is full. There’s also sensor to detect cats (load sensor, anti pinch, hall effect for the rotation) I will reuse if they still work after testing. I will keep the structure and motor (I’ve changed it 2 years ago) because it’s still functional. I’ve kept my old litter and try to find which component always failed but it’s a long work to reverse engineering this card so I’ve decided to make a useful project, create an open source version of this litter.

I haven’t problem at this time but i’m not very confident…Ī movie from youtube of how it works normally (not mine because my litter doesn’t work anymore) : How ? ¶ Finally, last year when controller die again, I change for the new version “Litter Robot Open Air”. In 10 years, I’ve changed many parts to keep it working but the controller is not reliable, I have to change it every 2 years. I’ve cats at home and 10 years ago I’ve bought a very useful object: a self cleaning litter called “ Litter-Robot”. I’m a petrolhead so I’m always working on projects around cars, but this time I’ll make something different. More informations can be found on my final project page here. This week I worked on defining my final project idea and started to getting used to the documentation process.
