JOINT DEVICE FOR ROBOT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18096434 titled 'JOINT DEVICE FOR ROBOT
Simplified Explanation
The abstract describes a joint device for a robot that includes multiple friction wheels and a driving device. When the first and second friction wheels rotate in the same direction, a third friction wheel rotates in a pitch direction, and when they rotate in different directions, the third friction wheel rotates in a roll direction.
- The joint device consists of a first shaft and a second shaft, with the second shaft perpendicular to the first shaft.
- A first friction wheel is supported by the first end of the first shaft, and a second friction wheel is supported by the second end of the first shaft.
- A driving device is used to rotate both the first and second friction wheels.
- A third friction wheel is supported by the first end of the second shaft and makes contact with the first and second friction wheels.
- When the first and second friction wheels rotate in the same direction, the third friction wheel rotates in a pitch direction.
- When the first and second friction wheels rotate in different directions, the third friction wheel rotates in a roll direction.
Potential Applications
- Robotic arms and manipulators
- Industrial automation
- Assembly line robots
- Surgical robots
Problems Solved
- Provides a joint device that allows for both pitch and roll movements in a robot.
- Simplifies the design of the joint device by using friction wheels instead of complex mechanisms.
- Enables precise control of the robot's movements.
Benefits
- Increased flexibility and range of motion for robots.
- Simplified and compact design.
- Improved precision and accuracy in robot movements.
- Cost-effective solution compared to traditional joint mechanisms.
Original Abstract Submitted
A joint device for a robot is provided. The present joint device includes: a first shaft; a second shaft disposed perpendicular to the first shaft; a first friction wheel rotatably supported by a first end of the first shaft; a second friction wheel rotatably supported by a second end of the first shaft; a driving device configured to rotate each of the first friction wheel and the second friction wheel; and a third friction wheel rotatably supported by a first end of the second shaft, and contacting the first friction wheel and the second friction wheels, wherein when the first friction wheel and the second friction wheel rotate in the same direction, the third friction wheel rotates in a pitch direction, and when the first friction wheel and the second friction wheel rotate in different directions, the third friction wheel rotates in a roll direction.
