Example implementations relate to generating instructions for robotic tasks. A method may involve determining task information of a path-based task by an end-effector on an object, where the task information includes (i) at least one task parameter, and (ii) a nominal representation of the object. The method also involves based on the task information, determining one or more parametric instructions for the end-effector to perform the task, where the one or more parametric instructions indicate a toolpath for the end-effector to follow when performing the task. The method also involves generating, based on sensor data, an observed representation of the object, and comparing the observed and the nominal representations. The method further involves based on the comparison, mapping the parametric instructions to the observed representation of the object. The method yet further involves sending the mapped instructions to the end-effector to cause the robotic device to perform the task.

Methods and apparatus are described for depositing materials at a precise location. The deposition is accomplished by using CNC control and a nozzle guide.

A laser processing robot system and a laser processing method, by which the motion accuracy of a robot in the system can be improved and laser processing with high accuracy can be carried out. The robot system is configured to: execute a first robot motion for moving an laser irradiation device to a predetermined command position; measure an actual three-dimensional position of the irradiation device in the first robot motion; calculate a deviation between the command position and the measured actual three-dimensional position of the irradiation device in the first robot motion; store the calculated deviation as a time series of deviation data; and execute a second robot motion in which a robot motion similar to the first robot motion is executed while correcting the laser irradiation position so that the laser irradiation position coincides with a desired position, based on the stored deviation data.

Embodiments of present disclosure relates to efficient control system and method for controlling operation of at least one machine in an industrial environment. The control system comprises a target path correction unit and a position correction unit. The target path correction unit is configured to modify a target path fed to the at least one machine, based on real-time spatial position of the at least one machine. The position correction unit is configured to correct real-time operating position of the at least one machine. The position correction unit corrects the real-time operating position by sensing one or more parameters related to the at least one machine and displacing operating tool of the at least one machine, based on the one or more parameters. The control system achieves tight tolerance in manufacturing of large structures inexpensively and eliminates the need of high skilled operator to operate the machine.
