We only just created VRMotionSim.com, but this project has been underway for more than a year. More details to follow, but we just got our first 2-DOF VR Motion Simulator prototype up and running! Video below.
The simulator moves +/- 45 degrees in pitch and roll, at up to 30 degrees a second. In the video, the speed is dialed down because the frame isn’t quite rigid enough, and accelerating quickly causes it to bounce. That problem will be addressed in a future revision.
The motion is controlled by two custom linear actuators. Each uses a 2.3 kW servo motor connected via a gearbox to a timing belt. The actuators are rated for 800 pounds of continuous force at up to 22 inches / second, with peak forces exceeded 1600 pounds. That’s more than enough to move the gimbal comfortably.
Control is handled on this version with a PLC, which is in turn connected to a PC. The simulation is our own custom game built in Unity.
This is still an early prototype and we have a lot of work to do, but getting the entire system up and running is a huge milestone for us!
