Research on Force Interaction Devices Specialized for Blind Guidance Robot

Abstract

Abstract: As a new type of human-computer interaction, physical human-robot interaction is very common in guide robots and is the mainstream of future development. However, the force interaction device is hard to choose according to actual application requirements. In this paper, we compared the force transmission characteristics of three interaction mediums: rigid rod, spring-damping, and cable. The result shows that the rigid rod will bring a force impact on blind users when the robot’s motion state switches, while the spring-damper can not perform well in its response and stability. In contrast, the cable is more suitable in this area for its fast response and stability, moreover, it does not impose a dramatic impact when imposing an excitation force.
