The present invention provides a low cost solution for a hybrid reality interaction system with passive haptic feedback, using a humanoid robot as the trunk of virtual human, using realistic facial models to create virtual images, and the virtual image is superposed on the head of the humanoid robot accurately. The virtual image enhances the facial details of the humanoid robot, enhances the appearance of the robot, and interacts with the user by such a virtual and real image. Compared with the virtual image of the trunk-less human, the virtual image provides the user with passive tactile force feedback, greatly enhances the reality of the virtual human, and enhances the interactive experience of the virtual human system. At the same time, compared with the virtual human 'U-Tsu-Shi-O-Mi' with power feedback, the invention does not use the special hardware tracking device, uses the tracking mode based on three-dimensional marker points to track the position of the registered virtual image, and utilizes the RGB camera to realize the fusion of the virtual image and the real image, thus saving the tracking cost.

A solar concentrator is composed of the cascading of the first light guiding module and a second light guiding module. The solar light is collected and guided simultaneously toward the light propagation destination by the light guiding modules. By cascading the light guiding modules in the direction of guiding, the solar concentrator has thinner thickness than the traditional concentrator and has a zero back focal distance to reduce the assembly cost. The solar concentrator utilizes the optical design concept of coincident image points from both the relay and converging optics such that the optical flux is increased in the cascading light guiding modules while the light propagation direction within the concentrator is maintained.

The invention discloses an array type solar oblique-axis tracking device. The array type solar oblique-axis tracking device mainly comprises a reducer, a primary tracking motor, a secondary tracking motor, a tracking output shaft, a sensor, a longitudinal shaft rotating bracket, a primary tracking driving arm, a driving knuckle bearing, a primary connecting rod, a secondary connecting rod, and solar energy oblique single-axis tracking brackets, wherein secondary tracking driving arms and driven knuckle bearings are mounted on the solar energy oblique single-axis tracking brackets. When the primary tracking motor is broken, the secondary tracking motor provides tracking power, so that the photovoltaic power generation array can continuously work normally, and the maintenance personnel have sufficient time to maintain and replace the broken main tracking motor; both of the primary tracking motor and the secondary tracking motor with the redundant backup function are utilized to realize the purpose of using the tracking driving capability output by the same reducer to drive a plurality of solar energy oblique single-axis tracking bracket arrays, so as to reduce the number of motors in the former single-motor tracking situation, reduce the failure quantity and lower the tracking cost.
