Abstract
A system for promoting safety of a robotic appendage includes: a robot controller; and a robot controllable by the robot controller, the robot controller configured to compute an estimated power draw of a planned trajectory of the robot, the robot controller further configured to modify the planned trajectory to prevent the estimated power draw from exceeding a power limit; the robot comprising: an appendage; an appendage controller configured to control the appendage; and a breaker configured to limit power delivered to the appendage. A system for promoting safety of a robotic appendage includes a plurality of robots operably connected with each other, the robots configured to communicate with each other regarding estimated power draw characteristics.

A system for promoting safety of a robotic appendage, comprising:
- a robot controller;
- and
- a robot controllable by the robot controller, the robot controller configured to compute an estimated power draw of a planned trajectory of the robot, the robot controller further configured to modify the planned trajectory to prevent the estimated power draw from exceeding a power limit,
- the robot comprising:
- an appendage;
- an appendage controller configured to control the appendage;
- and
- a breaker configured to limit power delivered to the appendage.
A method for promoting safety of a robotic appendage, comprising:
- computing, by a robot controller configured to control a robot, the robot comprising:
- an appendage;
- an appendage controller configured to control the appendage;
- and a breaker configured to limit power delivered to the appendage, an estimated power draw of a planned trajectory of the robot;
- and
- modifying, by the robot controller, the planned trajectory to prevent the estimated power draw from exceeding a power limit.
A method for promoting safety of a robotic appendage, comprising:
- receiving, by a breaker configured to limit power delivered to an appendage of a robot, the robot comprising:
- the appendage;
- an appendage controller configured to control the appendage;
- and the breaker, from a robot controller configured to control the robot, an estimated power draw of a planned trajectory of the robot;
- receiving, by the breaker, from the robot controller, an alert that the power draw is likely to exceed the power limit;
- and
- terminating delivery of power to the appendage, by the breaker, when the power draw exceeds the power limit.
A system for promoting safety of a robotic appendage, comprising:
- a plurality of robots operably connected with each other, the robots configured to communicate with each other regarding estimated power draw characteristics.
