A robot joint space point-to-point movement trajectory planning method. Joint space trajectory planning is performed according to the displacement of a robot from a start point to a target point during PTP movement and a limitation condition of a preset movement parameter physical quantity of each axis in a robot control system. An n-dimensional space is constructed by taking each axis of the robot as a vector, wherein n&#x2265;2, and the movement parameter physical quantity of each axis of the robot is verified according to a vector relationship between the n axes of the robot, so that a trajectory planning curve of each axis of the robot satisfies the limitation condition of the preset movement parameter physical quantity. The method has a small amount of calculations and strong real-time performance, the movement curves are mild, the control time is optimal, and the algorithm execution effect is good.

A dual system component-based industrial robot controller having a standard operating system, a real-time operating system, a route management module, a soft bus, a driver management module, a motion control module, a PLC module, an IO module, a teach pendent interface module and a protocol stack module. The controller employs a component-based structure and the components are operated respectively under a non real-time standard operating system and a real-time operating system, and supports distributed processing. The communications and function calls among the components are carried out by the route management module and the soft bus. The components in communication are managed through the route management module. The driver management module provides communications among other modules with a consistent interface which accords to the DS402 standard, and a servo driver that accords to this interface standard can be readily integrated into the controller. A user can develop function module components and add the same to the system, and the open-type interface of the controller enables the controller to connect hardware without limitations.
