6 | The Future of Robotics Texas Instruments What amount of payload (weight) and reach will the robot have? If the robot has to move heavy objects, it needs to have enough force on the motors to enable that capability. This force is generated with electric energy and is provided to the motor from the power stage. This power requirement is part of deciding whether the robot will be a high- or low-voltage system. A high- voltage robot system will require defined isolation architecture for safe operation. Will the electronics be centralized into the system controller? In a centralized system, the robot controller cabinet includes most of the electronic modules that control the robot manipulator. Figure 2 is an example of a centralized robot. In a decentralized system, some of these modules move to the robot manipulator to support various factors. This includes the form factor of the cabinet, cabling, and more. Figure 3 is an example of a decentralized robot. When decentralizing electronic content, it is essential to remember that the environments where the electronics are now used are not the same as the environments of a centralized system. This environment change necessitates a re-specification of the electronics and typically requires redevelopment of part of the system. Figure 2: Example of a centralized robotic system.
