A joint structure includes a locking mechanism for switching a free state in which a second element is independent from a first element and capable of moving, and a locked state in which the second element is fixed to the first element. The locking mechanism includes a first member joined to the first element, a second member joined to the second element, and a flexible wire-shaped member in which one end thereof is attached to the second member and another end thereof is led out to the outside of the joint structure via a through hole provided in the first member. The joint structure enters the locked state by the wire-shaped member being pulled to bring the second member into contact with the first member, and enters the free state by the wire-shaped member being fed to separate the second member from the first member.

Joint structure for robot

A joint structure for connecting a first element and a second element included in a robot includes a Stewart platform that controls a position and/or an angle of the second element relative to the first element. The Stewart platform includes a first member to be joined to the first element, a second member to be joined to the second element, multiple legs connecting the first member and the second member, a driver that changes an effective length of each of the legs to change a position and/or an angle of the second member relative to the first member, and a soft structure that elastically changes the effective length of each of the legs in response to an external force applied to the second member and restores the effective length of each of the legs in response to the external force being removed.

A control apparatus of a robot may include a state obtaining unit configured to obtain state observation data including flexible related observation data, which is observation data regarding a state of at least one of a flexible portion, a portion of the robot on a side where an object is gripped relative to the flexible portion, and the gripped object; and a controller configured to control the robot so as to output an action to be performed by the robot to perform predetermined work on the object, in response to receiving the state observation data, based on output obtained as a result of inputting the state observation data obtained by the state obtaining unit to a learning model, the learning model being learned in advance through machine learning and included in the controller.
