ROBOT ARM
First Claim
1. A robot arm, comprising:
- a drive gear that has a shaft;
a gear frame being capable of turning about the shaft of the drive gear;
a first follower gear being capable of turning, in synchronization with the drive gear, about a shaft fixed to the gear frame, in a direction opposite to the turning direction of the drive gear;
a transmission control mechanism being capable of locking the first follower gear to the drive gear;
an arm that moves in synchronization with the first follower gear; and
a collision detection unit that is capable of detecting a collision between the arm and an obstacle, whereinthe transmission control mechanism unlocks the first follower gear from the drive gear in response to the detection, by the collision detection unit, of collision between the arm and the obstacle.

Abstract
A robot arm has: a drive gear that has a shaft; a gear frame being capable of turning about the shaft of the drive gear; a first follower gear being capable of turning, in synchronization with the drive gear, about a shaft fixed to the gear frame, in a direction opposite to the turning direction of the drive gear; a transmission control mechanism that is capable of locking the first follower gear to the drive gear; an arm that moves in synchronization with the first follower gear; and a collision detection unit that is capable of detecting a collision between the arm and an obstacle. The transmission control mechanism unlocks the follower gear from the drive gear in response to detection, by the collision detection unit, of collision between the arm and the obstacle.

9. A robot arm, comprising:
-
a drive gear that has a shaft; a gear frame being capable of turning about the shaft of the drive gear; a first follower gear being capable of turning, in synchronization with the drive gear, in a direction opposite to the turning direction of the drive gear; a transmission control mechanism that is capable of locking the first follower gear to the drive gear; an arm that moves in synchronization with the first follower gear; and a collision monitoring unit that monitors a collision between the arm and an obstacle, wherein the transmission control mechanism unlocks the first follower gear from the drive gear when the collision monitoring unit detects a possibility of collision between the arm and the obstacle that stands in a movement direction of the arm.
