Abstract
An integrated control system for a work robot may be used for controlling multiple work robots as well as multiple work tools connected to the work robots. The integrated control system includes a robot control central processing unit (CPU), at least one work control CPU, a shared memory, and a system bus constructed to transmit information between each of the CPUs and the shared memory. The robot control CPU, the work control CPU, and the shared memory are connected to the system bus.
Claims7
An integrated control system for a work robot comprising:
- a robot control CPU for operating a number of robots, the robot control CPU being separate from the number of robots;
- at least one work tool control CPU;
- wherein the at least one work tool control CPU is separate from the number of work tools, and separate from the robot control CPU;
- and
- wherein the at least one work tool control CPU includes a pressing force control CPU for spot welding and a welding current control CPU for controlling a current associated with the spot welding, each of said robot control CPU, said pressing force control CPU, and said welding current control CPU being formed in the form of a board and being separate from each other;
- a shared memory shared by said robot control CPU and said work tool control CPU;
- and
- a system bus constructed to transmit information between each of said CPUs and said shared memory, wherein said robot control CPU, said work tool control CPU, and said shared memory are coupled to said system bus and are integrated with each other through said system bus so that said system bus is used in common with said CPUs and said shared memory.
An integrated control system for a work robot comprising:
- a robot control CPU for operating a number of robots, the robot control CPU being separate from the number of robots;
- at least one network control CPU for transmitting and receiving signals between each of the robots, the at least one network control CPU being separate from the robot control CPU;
- at least one work tool control CPU for operating a number of tools when the robots are operating, the tools being connected to the robots;
- wherein the at least one work tool control CPU is separate from the number of work tools, and separate from each of the other CPUs;
- and
- wherein the at least one work tool control CPU includes a pressing force control CPU for spot welding and a welding current control CPU for controlling a current associated with the spot welding, each of said robot control CPU, said pressing force control CPU, and said welding current control CPU being formed in the form of a board and separate from each other;
- a shared memory, shared by the robot control CPU, the at least one network control CPU, and the at least one work tool control CPU, the shared memory storing data associated with operation of the robot control CPU, the at least one network control CPU, and the at least one work tool control CPU;
- and
- a system bus constructed to (i) transmit information between the robot control CPU, the at least one network control CPU, and the at least one work tool control CPU and the memory, wherein all of the CPUs and the memory are coupled to the system bus and are integrated with each other through said system bus, and (ii) provide for synchronous operation of the robots, and the tools when the information is transmitted.
