Based on the theory of space coordinate transformation, kinematics equat!ons of RFP are formulated; followed by applying a method of modeling using 3DMAX software to build an RFP's 3D geometric model before a 3D kinematics simulation system of RFP is completed based on virtual reality technology and Open Inventor VC + +. Test results have indicated that this system can perform RFP's kinematics simulation in virtual environment. It can also imitate RFP's motion states and environmental features well. Moreover, not only can better real-time performances and interactions be achieved but also operator's vision telepresence be enhanced, therefore this approach may help lay the foundation for the realization of RFP's teleoperation with vision telepresence.展开更多

Firstly,the environment map is built based on Bayes rules. Then,the probability searching strategy based on the environment map was designed. Every grid of the searching area was assigned searching expectation value, and robots selected the grid with the highest expectation value as its searching target. The simulation results show the search time reduces greatly,which proves the feasibility and validity of the given algorithm under unknown fire condition.展开更多
