COVR – Towards Simplified Evaluation and Validation of Collaborative Robotics Applications Across a Wide Range of Domains Based on Robot Safety Skills

Challenges surrounding human safety have become one of the main barriers to the promotion and availability of collaborative robotics technology in different domains. The EU-funded project “Being safe around collaborative and versatile robots in shared spaces” (COVR) aims to break down these barriers to support more widespread use of collaborative robots in a wide range of industries and domains (e.g. manufacturing, logistics, healthcare and rehabilitation, agriculture). In this paper, we will describe our approach to engage various stakeholders and encourage widespread use of collaborative robots. This includes the development of a toolkit employing a methodology based on robot safety skills, and the development of a set of testing protocols that clearly define the safety-related validation procedures.

Assessing Safety and Performance Indicators in Rehabilitation Robotics

Healthcare is one of many domains where robots interacting with humans are becoming increasingly relevant. New technologies are being developed but the deployment in rehabilitation is restricted by a lack of unified testing methodologies. The two European projects COVR and EUROBENCH are working to break down those barriers. The goal of this contribution is to provide an overview of both projects and how they will contribute to a unified testing methodology for safety and benchmarking.

Prototype Measuring Device for Assessing Interaction Forces between Human Limbs and Rehabilitation Robots - A Proof of Concept Study

Rehabilitation robots can provide high intensity and dosage training or assist patients in activities of daily living and decrease physical strain on clinicians. However, the physical human robot interaction poses a major safety issue, as the close physical contact between user and robot can lead to injuries. Moreover, the magnitude of forces as well as best practices for measuring them, are widely unknown. Therefore, a measurement setup was developed to assess normal and tangential forces that occur in the contact area between an arm and a splint. Force sensitive resistors and a force / torque sensor were combined with two different splint shapes. Initial experiments indicated that the setup gives some insight into magnitudes and distribution of normal forces on the splint-forearm-interface. Experiment results show a dependency of force distributions on the splint shape and sensor locations. Based on these outcomes, we proposed an improved setup for subsequent investigations.

COVR – Towards Simplified Evaluation and Validation of Collaborative Robotics Applications Across a Wide Range of Domains Based on Robot Safety Skills

COVR is a European project driven by five national research and technology organizations. Through the development of an intuitive toolkit and a range of testing protocols for validation of safety for robots sharing space with humans, it will increase the safety of all types of collaborative robots across all domains with special attention to rehabilitation robotics.
