ROBUST POSITION CONTROL SYSTEM OF FLEXIBLE JOINT ROBOTS
A system for controlling a flexible joint robot includes a control input dimension conversion part configured to receive a control input of a robot and convert the Cartesian coordinate system of the control input to the rotating workspace coordinate system; an entire flexible joint robot dynamics part configured to receive the control input and a disturbance and output a control output by multiplying the control input reflecting the disturbance by at least one determinant; and a disturbance observer configured to reflect the estimated disturbance in the control input by calculating an estimated disturbance obtained by estimating the disturbance, wherein the disturbance observer includes a mutual reaction force removal part including a determinant for removing mutual reaction force between joints of the robot; a low-pass filter; and an estimated-disturbance dimension conversion part.
Path-Modifying Control System Managing Robot Singularities
A controller for robot arms and the like having mechanical singularities identities paths near the singularities and modifies those paths to avoid excessive joint movement according to a minimization of tool orientation deviation to produce alternative paths that minimize changes in the tool orientation such as can affect application such as welding, sealant application, coating and the like.
METHOD OF CALIBRATING A MOBILE MANIPULATOR
A method is provided for calibrating a manipulator and an external sensor. The method includes generating a first cloud map using depth information collected using a depth sensor, and generating a second cloud map using contact information collected using a contact sensor, which is coupled to an end effector of the manipulator. Thereafter, the first cloud map and the second cloud map are aligned to recover extrinsic parameters using the iterative closest point algorithm. The depth sensor is stationary relative to a base frame of the manipulator, and the depth information corresponding to a rigid structure is collected by capturing depth information from multiple vantage points by navigating the manipulator. The contact information is collected by moving an end effector of the manipulator over the rigid structure.
