The difficulty of robots space docking is to snatch sensor information exactly. Following the docking mechanism design
the sensor selection
modification and robot space docking based on sensor information are investigated. Considering the restriction of installing space and huge processing information
the method for space docking with two-dimensional position sensing detector(PSD)and light-emitting diode(LED)array is put forward. The PSD operating principle is analyzed
and the corresponding characteristics are tested
furthermore the method adding the optical device to PSD light-sensitive surface is suggested to enlarge the detecting extension and reduce the dependence of lighting signal. In a self-Reconfiguration modular exploration robots system(RMERS)
the trajectory planning based on sensor information is carried out to validate the feasibility of space docking.
