I’ve already talked about the 2-DOF prototype, but since VRMotionSim.com wasn’t active until lately, we have no in-process photos or videos from the build. So, here’s a review! This isn’t a complete or exhaustive review – it’s just a collection of pictures and videos that I happened to have on-hand.
A huge part of this design involved linear actuator development. You can find details on that process in my previous post. Unlike the actuator design, the 2-DOF frame is still in its first revision, so we have plenty of work to do to get it ready for prime-time. 🙂
Below, we machine part of the profile used for the linear actuator.
Below, we are planing the outer yoke where the bearings will attach.
Early assembly test-fit. The attached actuator isn’t finished, but it’s mounted for test purposes.
Testing the roll axis with a functioning actuator!
Looking good, despite the terrible mess in my garage!
Control Box! We are using a Productivity 2000 PLC for control for now, but will eventually upgrade to a custom-designed control board for more advanced control.
Full assembly together and moved to my basement:
