Passivity is a necessary condition for a system’s stability, meaning that when energy is generated, a system may readily become unstable. Passivity can be enforced using energy-aware actuation that monitors the amount of energy that is injected into or extracted out of a system. This type of actuation requires an energy budget to be used to execute a task. Communicating these energy budgets should be done carefully as to prevent accidental generation of energy. Therefore, this paper proposes an energy transaction protocol to communicate energy budgets in a distributed robotic system to guarantee that passivity is kept in a system. Simulations are performed with a model of the protocol with a highly unreliable communication channel to verify that the protocol indeed keeps passivity.
