RT Conference Proceedings T1 Heli4: A parallel robot for scara motions with a very compact traveling plate and a symmetrical design A1 Krut, Sébastien A1 Company, Olivier A1 Nabat, Vincent A1 Pierrot, François AB This paper introduces Heli4 a new 4 degree-of-freedom parallel robot. It is inspired by the Delta architecture, but was designed to overcome its limitations, using an articulated traveling plate. Unlike most articulated traveling plates, Heli4's traveling plate is very compact. Among other positive aspects is its symmetrical design. This paper gives the geometrical models, and particularly the forward position relationship which can be obtained in a closed form. In a third part, a detailed study of the robot singularities is made by taking into account the not-so-classic internal singularities.
