Multi-sensor-based walking-aided robot man-machine interface and obstacle avoidance control method thereof

2015 
The present invention discloses a multi-sensor-based walking-aided robot man-machine interface and an obstacle avoidance control method thereof. The man-machine interface comprises a pressure acquisition module, an obstacle detection module and a controller. The pressure acquisition module is used for detecting an acting force applied onto the head part of an operator. The obstacle detection module is used for detecting surrounding obstacles. The controller is used for calculating the speed of a walking-aided robot based on data acquired by the pressure acquisition module and data detected by the obstacle detection module. Meanwhile, the controller controls the walking-aided robot to facilitate the walking and avoid obstacles based on the speed of the walking-aided robot. The obstacle detection module is composed of a laser sensor and a high-speed USB data line and is capable of detecting surrounding obstacles. The controller is in communication with the pressure acquisition module and the obstacle detection module and is used for analyzing and calculating the acquired data to obtain an appropriate speed, then sending the speed to an external communication interface and guiding the operation of the operator so as to ensure the control security. The man-machine interface and the obstacle avoidance control method thereof are accurate to control, high in real-time performance, strong in portability and low in cost.
