Abstract
In this research, a new 2D-haptic joystick featuring a 2D-gimbal mechanism and two bidirectional magneto-rheological actuators (BMRAs) is designed, manufactured, and experimentally tested. Firstly, a new configuration of proposed 2D-haptic joystick is introduced; then, the BMRAs for force feedback of the haptic joystick are proposed, optimally designed, and experimentally evaluated. The BMRA has two disks rotating in opposite directions at the same speed. The two disks are placed inside a housing which is connected to the gimbal mechanism. The BMRA has two coils placed directly on each side of the housing. A prototype of the whole haptic joystick is then manufactured, and a controller is designed to feedback a required force to the operator. Force feedback performance of the haptic joystick is then experimentally investigated and compared with simulated one.
