In the system, each risk level is defined and a particular robot reaction assigned to it. The risk calculation is based on the recursive solution of the manipulator's kinematic problem for the evaluation of the horizontal distance components and the relative speed between operator and machine. Computational effort is minimized, since (1) the protection system procedures can be performed directly in the robot controller with the robot kinematic and dynamic calculations and (2) only the cylinder-shaped volumes around the operator's estimated position have to be defined in order to perform a probabilistic evaluation of the risk levels. Prelim inary testing on a simplified setup has validated the system's reliability, its insensitivity to background disturbances, and the ease of use of the sensors.<\/jats:p>","DOI":"10.1177\/027836499401300405","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T03:05:13Z","timestamp":1173582313000},"page":"334-342","source":"Crossref","is-referenced-by-count":2,"title":["Improving Active Accident Prevention in Robotized Manufacturing Plants"],"prefix":"10.1177","volume":"13","author":[{"given":"Roberto","family":"Giusti","sequence":"first","affiliation":[{"name":"Dipartimento di Energetica Universit\u00e0 di Firenze 50139 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Tucci","sequence":"additional","affiliation":[{"name":"Dipartimento di Energetica Universit\u00e0 di Firenze 50139 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1994,8,1]]},"reference":[{"key":"atypb1","volume-title":"Robot Motion: Planning and Control","author":"Brady, M.","year":"1982"},{"key":"atypb2","volume-title":"Adaptive Control of Mechanical Manipulators","author":"Craig, J.J.","year":"1988"},{"key":"atypb3","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1115\/1.4011045","volume":"22","author":"Denavit, J.","year":"1955","journal-title":"ASME J.
