This paper describes a theory and experimental results concerning a passive aerial acrobat robot without electric power. As the robot performs hand-to-hand on its flying trapeze, it utilizes no electricity but simply draws power from the mechanical potential energy of its swings. The robot, holding onto the trapeze, overcomes the rotation moment by aid of a counterbalance that is on the opposite side...
Most conventional robotic arms use motors to accelerate the manipulator. This leads to an unnecessary high energy consumption when performing repetitive tasks. This paper presents an approach to reduce energy consumption in robotic arms by performing its repetitive tasks with the help of a parallel spring mechanism. A special non-linear spring characteristic has been achieved by attaching a spring...
The application of the actuator to the robot that has a peculiar control function and output properties as seen in the living is expected. This paper shows two-joint robot arm system by motor drive with the planetary gear. The distribution at the end of arm is clarified. Moreover, to make better the ability of the actuator, higher force can be put out around the tip with the aid of the function of...
