RPR-equivalent Parallel robots: Design and Application
Abstract: RPR-equivalent parallel robots are presented, which can perform two rotations and one translation as a RPR serial chain. The proposed new parallel robots have advantages of specified rotation axis, simple kinematic model, which are beneficial to control and calibration. More importantly, these mechanisms can be fully or partly actuated with fixed linear actuators, leading to high stiffness, good dynamic response and high payload capability. To eliminate singularities and further improve stiffness, redundantly actuated RPR-equivalent parallel robots are constructed by adding proper kinematic chains on non-redundant ones and keeping necessary geometrical conditions. The proposed mechanisms are suitable to be used in the development of hybrid or parallel five-axis machining centers requiring good stiffness, high accuracy and manipulability.

Intelligent Control of Bionic Flapping-Wing Robotic Aircraft
Abstract: The bionic flapping-wing robotic aircraft is inspired by the flying ways of birds, which is regarded as a rigid-flexible coupling system. Our research focuses on the control system design of the aircraft, which makes the aircraft have great advantages such as high flexibility, low energy consumption and so on. However, flexible wings might produce the unexpected vibration and deformation under the influence of air flow. The vibration will degrade the flight performance, even shorten the lifespan of the aircraft. Therefore, designing an effective control method for suppressing vibrations of flexible wings is significant in practice. We have made several flapping-wing robotic aircraft for experiments. The control system is designed for vibration control and autonomous flying of the flapping-wing robotic aircraft.
