The invention provides an easy-to-manipulate manipulator comprising a manipulating part, a manual joint part that is driven directly by displacement of the manipulating part, a detection unit for detecting an amount of displacement of the manipulating part, a device that moves depending on the amount of displacement detected at the detection unit, an electric joint part that is driven by the device, and a selection portion for selectively determining whether the electric joint part is driven or not.
1. A manipulator, comprising:
a manipulating part,
a manual joint portion that is driven directly by displacement of the manipulating part,
a detection unit that detects an amount of displacement of the manipulating part,
a device that moves depending on the amount of displacement detected at the detection unit,
an electric joint portion that is driven by the device,
a selection portion that selectively determines whether the electric joint portion is driven or not, wherein the selection portion is a clutch, and
a disengagement position status holding portion configured to hold a position status between clutch plates upon disengagement of the clutch,
wherein the disengagement position status holding, portion comprises a convex portion provided on one clutch plate and a concave portion provided in another clutch plate.
2. The manipulator according to claim 1 , wherein when driving of the manual joint portion is selected at the selection portion, the clutch is engaged to transmit the displacement of the manipulating part to the manual joint portion.
3. The manipulator according to claim 1 , wherein when driving of the electric joint portion is selected at the selection portion, the clutch is disengaged to move the device depending on the amount of displacement detected at the detection unit.
4. The manipulator according to claim 1 , which further comprises:
a plurality of the electric joint portions, and an electric joint portion selection switch for selecting which of the plurality of the electric joint portions is to be driven.
5. The manipulator according to claim 1 , which further comprises:
a plurality of the electric joint portions,
a plurality of the devices corresponding to the plurality of the electric joint parts, respectively, and
a control unit for implementing operation based on the amount of displacement detected at the detection unit to issue commands to the plurality of the devices about how much each of the plurality of the devices is driven.
6. The manipulator according to claim 5 , wherein the operation is an operation for solving inverse kinetics.
7. The manipulator according to claim 1 , which further comprises:
a plurality of the manual joint portions, and
a manual joint portion selection switch for selecting which of the plurality of the manual joint portions is to be driven.
