Hi, I am working on a project which is based on Steward plattform (also called Hexapod or parallel kinematic/ robotic). For this device is not much space, therefor I need as small linear actuators as possible. The actuators need to have the following properties: Stroke up to 20mm, Force up to 100N, Velocity up to 40mm/sec . I already searched in the www but couldn't find some. Pneumatic actuators are not a solution, because they have to be moveable to each possition (which has to be accuracy). Hope that someone can provide me some information. Thanks for helping me.
Cheers Sebastian
