Abstract

We propose an application of robotics technology to the motion analysis of motorcycles. To construct a rider robot, we proposed the DCT mechanism as a steering and stabilizing equipment(DCT : Damping unit, Counter-steering angle, Temporary input).

This paper presents the experimental results of scale modeling. We made an electric motorcycle model that equipped with the DCT mechanism. We measured the steering angle and the rolling angle, aiming at resolution of the counter-steering phenomenon of motorcycles. The steering angle was measured by the contactless precision potentiometer, and the rolling angle was measured by the acceleration sensor.

This paper also shows the results of a simulation based on the Sharp* model that includes the rolling resistance of the front tyre, round profile of tyres and centrifugal force. In addition, we compare the Sharp's model and the Sharp* model.

The experimental results of counter-steering phenomenon coincide with the simulation results, and confirm that the DCT mechanism is very useful equipment for data sampling of unmanned motorcycles.
