This paper describes the morphing omnidirectional gripper which is able to grasp various objects with low melting point alloy. The deformable part of the gripper changes its shape by covering all directionof objects and makes the contacting area higher. In order to keep the high grasping force, proposed gripper does not need any additional energy thanks to the solid state of the deformable part including low melting point alloy. The design of the actual prototype model with cooling mechanism is shown and built. In addition, the usage of functional fluids for the morphing part is proposed. The basic performance of the blended material of low melting point alloy and magnetic fluid has been observed.

This paper describes linear load-sensitive continuously variable transmission with the spherical driving unit. This CVT mechanism consists of spherical drive, drive axis, motor housing, fixed bracket and linear sliding plate. It changes the reduction ratio continuously by inclination angle of active rotational axis. Additionally, this linear mechanism has a load-sensitive function by changing inclination of active rotational axis in response to the load. We have developed a linear load-sensitive continuously variable transmission and confirmed the effectiveness of the proposed mechanism.
