Open the CIPO recordAbstract From the Canadian patent
Single or multiple flexible robotic manipulator trunks can be made from individually activated three, degree-of-freedom, flexible robotic links. Threedimensional positioning and orientation of the distal end of each link is achieved exclusively by elastic deformation of the flexible link assembly without revolute or prismatic joints. The activating bending and torsional moments required for such a positioning are generated by the antagonistic action of a plurality of prestressed, inflatable laterally, bendable and axially extensible tubular actuators with the anisotropic, circumferentially reinforced walls. The positioning motion, working forces and manipulator arm stiffness are all …

Why it's free to use
- Filed April 2, 1991 and granted April 30, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 2, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
