Mobile robotic device having a collision sensor
First Claim
1. A mobile robotic device comprising at least one displaceable sensor member (8,9) for sensing a collision between the mobile device and a stationary object, whereby the sensor member (8,9) is disposed in a spring-loaded fashion so as to normally be in an extended position, and whereby means (12,13,14,15) are present for detecting the displacement of the sensor member (8,9) with respect to the mobile device, whereby said means comprise first detection means (12,13) for detection of a predetermined first displacement of the sensor member (8,9) and second detection means (14,15) for detecting a predetermined larger displacement of the sensor member (8,9), characterized in that the sensor member (8,9) is attached to a frame (6), whereby the sensor member (8,9) is displaced with respect to the frame (6) being said first displacement detected by said first detection means (12,13), and whereby the sensor member (8,9) together with the frame (6) can be displaced with respect to the mobile device for obtaining said larger displacement of the sensor member (8,9) detected by said first detection means (12, 13) and said second detection means (14,15), characterized in that said detection means comprise micro switches (12, 13, 14, 15) which are activated by the displacement of the sensor member (8, 9).

Abstract
A mobile robotic device comprising at least one displaceable sensor member (8,9) for sensing a collision between the mobile device and a stationary object. First detection means (12,13) are present for detection a predetermined first displacement of the sensor member (8,9) and second detection means (14,15) are present for detecting a predetermined larger displacement of the sensor member (8,9).
