A mobile robot is easy to be collided in a dynamic environment, and will also be knocked by people as a means of communication to send a command, so it is necessary for the robot to detect the bump information correctly and make a reasonable response. A 2-D (two-dimensional) accelerometer is fixed in a differential drive wheeled mobile robot to feel the occurrence of bump by picking up vibration signals...
Although mobile robots are installed sensors to detect the environment, it is still hard to avoid bump. On the other hand, a bump with the robot can be taken as a way to communicate with it, so it is necessary for the robot to perceive bumps and make a reasonable responds to it. The paper introduces a method to sense a bump by detecting the vibration caused by it with a 2-D (two-dimensional) accelerometer...
