Roomba bumpers
thingiverse
Roomba is a great autonomous vacuum cleaner but it has a tendency for getting stuck under things like refrigerators. These simple bumpers match the existing infrared (IR) sensor in height and diameter. If installed on top of Roomba they prevent it from getting stuck. Ideally you should use 4 and space them at about 3 inch (75 mm) distances from the main IR sensor. Bumpers can be attached to Roomba with a very small amount of acetone.
