Sensor for detection of obstacles for an autonomously moving robot, e.g. an automatic vacuum cleaner, is based on a surrounding shell whose movement is detected by optical sensors reliably indicating contact with an obstruction

摘要

Contact sensor, especially for detection of obstructions for an autonomously moving robot, in which the whole device is surrounded by an outer shell, with movements of the shell relative to the device detected using an optical sensor. Advantageously the shell is resistant to moment forces that would cause it to rotate about an axis. Hence the optical sensors are very accurate.
