Optional add-on module for all new Landroid models from 2019 onwards. It navigates around obstacles that others collide with. Daily collisions can also damage your trees, plants, and garden furniture. A Landroid with the ACS option avoids all of that: it effortlessly steers around obstacles. The Landroid uses automotive-quality ultrasonic sensors to detect obstacles. Easy installation - you just need to turn a few screws. The Landroid automatically recognizes the new module.
