Robot able to move on fixed or mobile working stations

A robotic system for carrying out tasks, and comprising:

• a. at least two working stations, at least one of said two working stations being a mobile station having means for moving said mobile station along a desired travel path, and a manipulating robotic arm for being connected to and carried by one of said two working stations;
• b. control means for generating control signals for controlling said robotic arm, said control means being controlled by a user/robot interface included in said mobile station, said user interface being used to control said robotic arm when said robotic arm is connected to said mobile station and used to control said robotic arm via emitter/receiver means also included in said mobile station when said robotic arm is connected to the other of said stations;
• c. means for supplying energy to said system, said means for supplying energy being included within each said working station;
• and
• d. displacement means for permitting said robotic arm to be interchangeably disconnectable from said one station and reconnectable to the other of said stations, said displacement means including a coupler means mounted to said robotic arm and at least two seating means, each of said working stations having one of said seating means mounted thereon, each said seating means including an elongate pin extending from a chamfered portion, said coupler means including a hollow cylindrical piece having two entrances for receiving the pins of said two seating means, said entrances including respective slanted portions for being nested with said chamfered portions of said seating means when said pins of said seating means are fully received in said entrances, said coupler means also including a balance bolt means for engaging the pin of the seating means of the station to which said robotic arm is to be connected and for simultaneously disengaging the pin of the seating means of the station to which said robotic arm is to be disconnected whereby to permit said robotic arm to be disconnected from said one station and connected to said other station.
