A HAPTIC WHEEL WITH PASSIVE TYPE ROTARY ACTUATOR BASED MR FLUIDS

摘要

The present invention relates to a haptic wheel using a magnetorheological fluid-based passive-type rotational actuator, and more particularly, to a haptic wheel using a magnetorheological-fluid-based passive-type rotational actuator. A wheel that receives a sense of force corresponding to the; an encoder coupled to one end of the wheel and sensing a rotation value according to a rotation input of the wheel; a MR fluid-based manual type rotation actuator coupled to the other end of the wheel, generating a sense of resistance to a rotation input transmitted through the wheel, and transmitting the generated force to the wheel; and a PCB plate for controlling the driving of the magnetorheological fluid-based passive type rotation actuator so that the user can feel a sense of resistance to rotation input through the wheel. According to the haptic wheel using the magnetorheological fluid-based passive type rotation actuator proposed in the present invention, a wheel that transmits a user's rotation input and receives a sense of force corresponding to the rotation input, is fastened to one end of the wheel, and the wheel An encoder that senses the rotation value according to the rotation input of the MR fluid, which is coupled to the other end of the wheel, creates a sense of resistance to the rotation input transmitted through the wheel, and transmits the generated force to the wheel. of a manual type rotation actuator, and a PCB plate that controls the driving of the magneto-rheological fluid-based manual type rotation actuator so that the user can feel the resistance to rotation input through the wheel. Although various senses are generated and provided, it is possible to enable the user to feel realistically through the wheel, such as the viscosity of the target application object of the executed program or the texture of the floor. In addition, according to the haptic wheel using the magnetorheological fluid-based manual type rotation actuator of the present invention, the magnetorheological fluid-based manual type rotation actuator is combined with the controller of the wheel interface used in a mouse or other input device, and the rotation of the wheel By creating various senses of input and providing the user with a sense of force such as the viscosity of the target application object or the texture of the floor according to the execution of the program, the viscosity of the object of the target application or the texture of the floor by the situation of the program execution It is possible not only to effectively provide a variety of forces, but also to experience and feel the force in various situations of program execution accordingly.
