Abstract
A robot hand and a robot according to an embodiment include a set of sliding parts, supporting units, a rotary unit, and a plurality of holding claws. The sliding parts slide in a direction to come close to or move away from each other. The supporting units are secured to the respective sliding parts. The rotary unit is attached to an end portion of at least one of the supporting units and rotates around an axis of rotation parallel to sliding shafts of the sliding parts. The holding claws are attached in directions orthogonal to the axis of rotation and different from one another.
Claims12
A robot hand comprising:
- sliding parts that slide in sliding directions to come close to or move away from each other;
- supporting units that are secured to the respective sliding parts;
- rotary units that are attached to end portions of the respective supporting units and rotate around an axis of rotation parallel to the sliding directions;
- a plurality of holding claws that are fixed to each of the rotary units rotatably around the axis of rotation in directions orthogonal to the axis of rotation and different from one another;
- a single rotary servo motor that rotates the rotary units around the axis of rotation;
- a spline shaft that is rotated by the rotary servo motor;
- and
- a plurality of belt pulley units that are provided corresponding to the respective rotary units and transfer the rotation of the spline shaft to the rotary units.
