In this paper, we introduce a quadruped robot designed for bounding gait with only one actuator per compliant leg. Under the analysis of the dynamics model of the robot, a new simple linear running controller using the energy control idea, which requires minimal task level feedback and only controls both the leg torque and ending impact angle, is proposed. It successfully executes fast running from...
The paper deals with the motion of turning in place of a spherical robot for military reconnaissance and unknown environment exploration developed by us. The robot belongs to a nonholonomic and under-actuated system. The robot has 3 DOF and 2 inputs. The motion of turning in place can make a spherical robot with higher dexterity and environmental adaptability. The mathematical model of the turning...
The colonoscope is an important surgical tool to diagnose various colon diseases. However, the conventional colonoscope usually causes the patient a great deal of discomfort and pain. In order to develop a colonoscope for less discomfort of the patient and less demanding operation techniques of the doctor, a novel snake-like robotic colonoscope is proposed in this paper. This robotic colonoscope adopts...
The mechanics and control specifications of a parent-children type robot system currently being built at Harbin Institute of Technology is proposed. The parent robot platform, called HIT-HYBTOR, weights about 25 kilograms, has four legs and wheels on its feet so that it can walk and step over barriers on rough terrain or drive by wheels accessing more speed on even ground. The power for leg joint...
