“…The sense of restraint exerted by the inflatable device through the seatbelt created a sense of sustained low frequency acceleration after the device was inflated. In [14], Toda et al designed a single degree of freedom seat simulator to examine the fatigue that bodies perceive after a long period of driving. The simulator consisted of a single degree of freedom chair and a steering wheel as well as visual effects; tests for physical fatigue were performed by adjusting the impact axis on the back.…”

In this study, we present a design and a control based on a microcontroller for a multi-axis servo motion chair. The main purpose was to provide the pilot with the tactile sensations required by the human body to increase the immersion of simulation training. With high system control reliability and multi-functionality, the proposed architecture was built with an effective split of the control tasks involved between a master controller and five slave drivers. To assess the effectiveness of the proposed control system, RS485 and RS232 communication transmission interfaces were provided for the control system to obtain related movement information. The performance of the motion chair was assessed through various experimental tests. The results confirmed that the proposed multi-core system-on-chip microcontroller (MCU) with independent communication and real-time control subsystems was feasible to control a multi-axis servo motion chair system.

“…The devices created the feeling of continuous low-frequency acceleration through the sense of restraint imposed by the safety belt after the devices inflate. In [10], the researchers designed a single DoF seat simulator to examine the fatigue the body perceived after prolonged driving. The simulator comprised a one-DoF chair, steering wheel, and visual effects and tested the body's level of fatigue through the adjustment of a surge axis on the back.…”

Design, Analysis, and Implementation of a Four-DoF Chair Motion Mechanism

In this study, the proposed design of a motion chair with four degrees of freedom (DoF) provides the pilot with the tactile sensations required by the human body to increase the immersion of flight simulation training. The chair includes a seat pan, a back pad, and a seat height. For the development of the proposed mechanism structure, the modular design is used to achieve the required displacement and acceleration. In addition, inverse kinematics is also constructed to meet the actuation needs. The control system can achieve real-time closed-loop control using an industrial computer, a motion control card, servo motors and drivers. This enables the structure to reach destinations with the shortest motion time and completes the required T-curve motion trajectory. The displacement, velocity, and acceleration of the designed structure are analyzed using SimWise4D software to verify the performance specifications of the structure. The experimental results indicate that the four-DoF control meets requirements of displacement, velocity, and acceleration.
