This work presents a novel calibration technique capable of simultaneously calibrating a camera’s intrinsic parameters and hand-eye-workspace relations. In addition to relaxing the requirement of a precise calibration reference to achieve manipulat

In this thesis, we propose the design of optimization for backlight module, based on the Lambertian LED. We used light reflection to design the compound mask. When light is passing through the compound mask, it could upgrade brightness, smoot

An optimized trajectory of multi-axis robotic manipulators is important and directly influences the performance of the executing task. In manipulators of seven or more axis, this optimization involves considerations regarding continuity of position a

The geometrical relationships among robot arm, camera, and workspace are important to carry out visual servo tasks. For industrial robots, the relationships are usually fixed and well calibrated by experienced operators. However, for service robots,
