2-DOF Axis Chair Simulator

Abstract

The main goal of this project is to design a low cost 2-DOF chair simulator. The chair simulator was intended to increase immersion in gaming, virtual reality, and training environments. The use of common methods that motion simulators use is based on costly multi-axis techniques with hydraulic actuators, high-end servos motors, and proprietary controllers driving them out of reach for students,hobbyists, and small VR setups. Our project, in contrast, offers an affordable locally available steel And fnally, DC gear motors and an Arduino based control setup with some complimentary hardware materials.You have a simulator with 2 degrees of freedom (2 DOF) pitch and roll. These are the most signifcant motion cues when emulating racing and flight simulations. Motor Rotation is converted through a custom steel frame and linkage mechanism into smooth, controlled chair movement. Using live game telemetry The system reduces relevant motion parameters (such as speed, acceleration and direction) by adjusting the chair’s movement. This allows for a real-time tilt of the playing surface, helping in-game movement feel more natural and immersive. The design doesn’t use industrial-grade components, specifcally to keep costs down and rather depends on straightforward fabrication techniques utilizing wide spread electronics, and a control algorithm characterized by feedback. These decisions signifcantly This cuts costs overall while keeping safety and responsiveness, reliability. The result is a simulator that becomes both practical and comfortable the ideal option for classrooms, local builders and gaming enthusiasts. The project major achievements include: • Designing a sturdy and robust motion platform with 2-DOF steel frame • Using DC motor, motor driver and easy to use arduino. • Implementing game telemetry, based motion cueing compatible with popular PC racing and flight games. • Achieving smooth, responsive, and safe tilting motion verifed through thorough testing. • Producing a highly cost-effective prototype far cheaper than commercial motion chairs. Overall, this project demonstrates that immersive motion simulation doesn’t need to be expensive. With affordable hardware, local materials, and accessible control technology, it’s possible to create a functional, reliable motion chair, making this work a valuable contribution for students, hobbyists, and small VR developers.
