OpenPHRI: an open-source library for safe physical human-robot interaction

Abstract

Open PHRI is a C++/Python general-purpose software scheme with several built-in safety measures designed to ease robot programming for physical human-robot interaction (pHRI) and collaboration. Aside from providing common functionalities, the library can be easily customized and enhanced thanks to the project's open-source nature. The OpenPHRI framework consists of a two-layer damping controller, depicted in Figure 1. This allows the user to provide compliance and other safety features at both the joint and task levels, depending on the application.
