A system and process is provided for controlling a robot path of a robot including providing a main path for movement of the robot based on path data having points along the main path and providing a safe evacuation path from each point in the main path to get to a safe position. The main path is formed with safety evacuation path considerations in mind such that along any point on ride path the robot can be safely moved to a safety point or to the unload position or safe position.

Robot trajectory control including emergency evacuation path system and method

A system for controlling a plurality of robots and a method for controlling said system. Said system comprises a plurality of controllers, each having an associated motion system adapted to control attached robots, with each motion controller being able to receive motion instructions from at least one motion instruction source and at least one of said motion instruction sources being a control program, as well as a computer network over which said controllers communicate. In this way, the invention can be applied to solve problems which are commonly encountered in coordination activities such as load sharing, mating of parts while processing, fixtureless transfer, teaching, manual motion of coordinated operations, and time coordinated motion.

Method and control system for controlling a plurality of robots

An object oriented motion system for controlling the movement of a robotic manipulator is presented. The motion system includes a trajectory generator object for producing a stream of machine joint commands. A kinematics object is operable to provide a set of robotic arm specific functions for the trajectory generator object. A servo object provides an interface to the servo system. The stream of machine motor commands are converted by the servo object to a stream of signals that drive the servo system, thereby controlling the trajectory of the robot arm.

Object oriented motion system

A trajectory generation system is provided for operating a robot in response to a motion command. The robot is a multi-jointed manipulator with an end-effector that traverses a trajectory. A Cartesian trajectory generator converts the motion command into a requested Cartesian positions vector and a requested Cartesian velocities vector. A Jacobian matrix of the manipulator defines the relationship between the manipulator joint velocities vector and the manipulator Cartesian velocities vector. A requested joint velocities vector is computed from the requested Cartesian velocities vector by way of the inverse of the Jacobian matrix. The requested joint velocities vector defines a planned state vector for the manipulator.
