Space mechanical arm three-dimensional simulation system

The invention discloses a space mechanical arm three-dimensional simulation system, and performs simulation control aiming at a three-dimensional simulation model created through adoption of an open-type graphic element program OSG. An instruction input interface module and an OSG simulation interface module are taken as interfaces between a space mechanical arm simulation platform and the external, receiving and processing of operator's control instructions are mainly completed, and an operating state of the simulation model is displayed in real time. An operator operates the simulation platform interfaces to trigger a response form, and sending and processing of the instructions are achieved via a task management module. The task management module and a data management module are used to coordinate and manage execution of various tasks and to complete management of related data in task operating processes. A path planning module layer contains a path planning module, mainly completes calls of a path planning dynamic link library and updates related contents in the data management module; and corresponding task planning can be completed through scheduling of the task management module.
