DIFFERENTIAL JOINT DEVICE FOR ROBOT, AND METHOD FOR DIAGNOSING STATE OF DIFFERENTIAL JOINT DEVICE FOR ROBOT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223189 titled 'DIFFERENTIAL JOINT DEVICE FOR ROBOT, AND METHOD FOR DIAGNOSING STATE OF DIFFERENTIAL JOINT DEVICE FOR ROBOT
Simplified Explanation
The abstract describes a differential joint device for a robot.
- The device includes a first shaft and a second shaft connected to it, extending in different directions.
- There are three friction wheels in the device, with one on each side of the first shaft and one at the end of the second shaft.
- The third friction wheel is in contact with the first and second friction wheels.
- The device also includes pitch and roll output encoders to detect rotation angles of the first shaft and third friction wheel respectively.
- There are two drivers, one for each of the first and second friction wheels, to rotate them.
Original Abstract Submitted
A differential joint device for a robot includes a first shaft extending in a first direction, a second shaft connected to the first shaft and extending in a second direction vertical to the first direction, a first friction wheel rotatably disposed on one side of the first shaft, a second friction wheel rotatably disposed on another side of the first shaft, a third friction wheel rotatably disposed at one end of the second shaft, the third friction wheel being in contact with the first friction wheel and the second friction wheel, a pitch output encoder disposed to detect a rotation angle of the first shaft, a roll output encoder disposed to detect a rotation angle of the third friction wheel, a first driver configured to rotate the first friction wheel, and a second driver configured to rotate the second friction wheel.
