Mechatronic design and control of rotary flexible joint

The model of rotational mechanical system is laboratory model intended to emulate a flexible joint on a robot or spacecraft and is also useful in the study of vibration analysis and resonance. This system is similar in nature to the control problems encountered in large geared robot joints where flexibility is exhibited in the gearbox. The aim of this paper is to design such mechatronic system with considerable elasticity, for educational purposes, using computer aided design (CAD). Control algorithm is proposed for designed mechanical system in order to reduce effects of flexibility.
