the vestibular system can’t sense motions below someangular speed threshold - this allows simulating linear acceleration - you change the pitch of you seat with angular rate below the threshold, in the result you don’t register the angular movement, but you can feel the total force direction (resulting from gravity in your sim chair) as during the acceleration - no longer perpendicular to your horizontal plane (“floor”),.Once the roll stops, generally you’ll enter a coordinated 1G turn, so no matter the bank angle, your body feels a return to level 1G.ĭepending on the bank angle, in the coordinated turn, the centrifugal force and gravity adds, so it is always more than 1G, but indeed you can’t simulate this in the moving chair (you can’t have more then 1G in the chair).ģ0 years ago, as my masters thesis I developed 6DOF platform control system which also involved modeling vestibular system. I hope this project inspires others to build their motion VR rig versions. Off-the-shelf Saitek rudder pedals (the only non-DIY control)Ī comparable off-the-shelf setup would cost me ~$4500 and would not be as universal and intuitive as mine.Extra 2-axis analog thumbstick for space simulators or extra functionality.Left-side Switch Box with 9 switches and 3 analog pots. ![]() HOTAS Throttle with analog Thumbstick, convertible to heli Collective control with RPM axis.Boeing 737-style Throttle Quadrant, 8-axis (2 Throttles, 2 analog thrust reversers, Speedbrake, Flaps, Prop, Mixture), TO/GA and T/A disconnect buttons, Trim Wheel, Aileron/Rudder trim knob, magneto rotating 5-pos knob, fuel cut-off switches, starter and APU start buttons.Switch Box with lockable spring-loaded Gear Lever, 11 switches and 2 analog pots (MobiFlight).Encoder box with 6 3D-printed dual encoders (using cheap single encoders), 8 buttons and 3-pos switch, driven by custom MobiFlight profile.A 3-axis system with smooth bungee resistance, soft return and no central detent. Pendular Yoke with extended travel (frictionless hall sensors), convertible to Joystick / Cyclic configuration with extended throw and precision, designed and built with frictionless hall sensors.2 Vibration Transducers (butt-kickers) driven by SimShaker software.2DOF Motion platform with seat, driven by FlyPT Mover software (motion cues based on plane orientation and acceleration data). ![]() ![]() The build includes the following fully custom-built systems and controls:
