Abstract: Hand-held position teaching device (12, 42, 82, 104) and a method for teaching a robot a position and an orientation with a Hand-held position teaching device, wherein the teaching device comprises a teaching device-TCP (18, 56), force sensors (32, 50, 52) and inertial sensors (20, 58) and its' coordinate system is calibrated to the robots' coordinate system, and wherein the teaching device is held in the desired position and orientation and transmits the teaching device-TCP position and orientation to the robot controller (116) to be stored. The user (102) may also apply force to a gripper (44, 48, 84, 88) of the teaching device and grip a workpiece (108, 110) in order to teach a gripping function. The robot controller may afterwards use the plurality of stored positions and orientations to control and move the robot. This is significantly easier than moving the whole robot arm with a teaching device mounted thereon or controlled by it. The user interface of the gripper comprises springs.

Abstract: A robot teaching system and method by applying a force on a teaching pendant (mechanical interaction tool 14,44,84), wherein the sensed force and teaching pendant's position and orientation is transmitted to the robot controller (20,68,116,158) to be stored. The teaching pendant may comprise a gripper with finger (46,48,86) operated by a spring mechanism (88). The robot arm is moved according to the applied force, position and orientation of the teaching pendant and a robot program is generated based on these data. During future execution of the a robot program, a robot gripper is foreseen to automatically apply a force on a workpiece or an object to be gripped, which is corresponding exactly to the afore mentioned manually applied force.

Abstract: A method for trajectory planning in a robotic system comprising at least two robotic units (1, 2, 3) is disclosed. In the method, a state vector of each robotic unit comprises position components Formula (I) and velocity components Fromula (II) and is variable with time as a function of input Formula (III) into said each robotic unit (1, 2, 3) and independently from input into every other robotic unit, and a trajectory which defines the motion of said robotic units from an initial state (X0) to a final state (XTf) is determined by finding the trajectory that minimizes a predetermined cost function (J). The cost function (J) is set (S3) to be a function of the state vectors of all of said at least two robotic units, and is minimized (S4) under a constraint which defines a vector difference between at least the position components Formula (iv) of the state vectors of said at least two robotic units (1, 3; 2, 3) at an instant (f(1), f(2)) of said trajectory.
