Design and development of a novel type of table tennis aerial robot player with tilting propellers

Table tennis has long fascinated roboticists as a particularly difficult task which requires fast movements, accurate control and adaptation to task parameters. In addition, the development of such devices is useful for educating the undergraduate students. Up to now, several groups have developed robotic manipulators playing table tennis and other commercial interactive robots. Moreover, drones are booming right now, and they can cover a larger workspace than manipulators, for a lower device volume and at a lower price. In this context, this paper aims to propose a drone playing table tennis to analyze the benefits and the disadvantages for this task. Most vertical takeoff and landing (VTOL) vehicles are not fast enough to reproduce hitting motions. The proposed prototype is an innovative quadrotor combining a tilting propeller and a state-dependent iterative linear quadratic control (iLQR). The performance of the proposed solution is evaluated with real experiments that show the success of the approach, reaching hitting rates of 40%.

Virtual and Real-Time Synchronous Interaction for Playing Table Tennis with Holograms in Mixed Reality

Real-time and accurate interaction technology is required to realize new wearable Mixed Reality (MR) solutions. At present, the mainstream interaction method relies on gesture detection technology, which has two shortcomings: 1. the hand feature points may easily be obstructed by obstacles and cannot be detected and 2. the kinds of gesture that can be recognized are limited. Hence, it cannot support complex interactions well. Moreover, the traditional collision detection algorithm has difficulty detecting the collision between real and virtual objects under motion. Because location information of real objects needs updating in real time, it is easy to lose collision detection under high speeds. In the implementation of our system, Mixed Reality Table Tennis System, we propose novel methods which overcome these shortcomings. Instead of using gesture detection technology, we use a locator as the main input device and build a data exchange channel for the devices, so that the system can update the motion state of the racket in real time. Besides, we adjust the thickness of the collider dynamically to solve the collision detection problem and calculate rebound results responding to the motion state of the racket and the ball. Experimental results show that our method avoids losing collision detection and improves the authenticity of simulation. It keeps good interaction in real time.
