In this talk, I would share my experiences of developing intelligent robot within the categories of challenging bipedal humanoid robots, quadrupedal robots, and robotic manipulators. The abovementioned robots are configured as a large number of actuators to perform complex and flexible motions. Hence, in addition to the presentation of challenging mechatronics and hands-on practice skills, the motion planning issues within specific control systems, computer vision and machine learning are also addressed. Finally, a number of case studies done in my laboratory would be reported for knowing the skill learned and merit obtained of experiencing intelligent robotics projects.
