Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for executing one or more actions based on a safety skill. One of the methods comprises receiving, by a robotics control system, a skill that defines actions to be performed by a robot controlled by the robotics control system, where the skill specifies one or more safety constraints that represent safety conditions that must be satisfied before the robotics control system can execute the actions on the robot; populating, by the robotics control system, a safety database with the safety constraints specified by the skill; initiating execution of the skill by the robot; determining, by a safety control subsystem of the robotics control system, that the safety conditions specified by the skill have not been satisfied; and in response, modifying, by the robotics control system, execution of the actions defined by the skill.
