Digital System Power for Robotics might be related to arm motion, reducing the power required for taking certain actions in an optimal way; or robotic power considerations might relate to an EV active-suspension, for example. The robotic arm may be plugged into the grid, while the EV active-suspension is most likely a mobile battery?
In either case, one needs to monitor the current energy stored, vs. the energy required for the anticipated action. Next, the digital system can determine if there is sufficient energy for this action. If yes, then perform the action; if no, then system needs to determine if the action is critical, whether to take the action despite lack of sufficient energy, or skip? The Robotic arm may have a local battery storage, despite grid connection to minimize robotic cable sizes.
The digital system would need to calculate the anticipated position, velocity, and acceleration vectors of the mechanical mass being moved. The power/energy can vary based on these values; VisualSim has access to current, cumulative power for each device in the digital system; which allows one to accurately model the movement of these masses.
