Focusing Device Based on Overconstrained Mechanism. (August 2019) - Racila, L D
Abstract: The paper presents an application based on an exceptional 6R overconstrained mechanism. This mechanism is started from 6R Wohlhart symmetric mechanism, not in its classical spatial position but a different one, with three non-adjacent joints constrained to remain in a fixed plane. This disposition allows the conception of an interesting device, a focusing table, capable of obtaining good accuracy.
