Meet the PI H-811.I2: a 6-axis motion platform with micromanufacturing and medical applications that can handle load up to 5kg, with a travel range of +/- 17mm and 21 degrees. It can move with velocity to 10 mm/s. It comes with a simulation tool, so you can check whether it can handle the loads, forces, torques occurring in an application.
The above video shows this 6-axis robotic system in action. More info is available here.
