    Abstract: A method and apparatus for interfacing the motion of a user-manipulable object with an electrical or computer system includes a user object physically contacted by a user. A gimbal mechanism is coupled to the user object, such as a joystick or a medical tool, and provides at least two degrees of freedom to the user object. The gimbal mechanism preferably includes multiple members, at least two of which are formed as a unitary member which provides flex between the selected members. An actuator applies a force along a degree of freedom to the user object in response to electrical signals produced by the computer system. A sensor detects a position of the user object along the degree of freedom and outputs sensor signals to the computer system. Another embodiment includes a host computer system and a local microprocessor, separate from the host computer, for communicating with the host computer and controlling the forces output by the actuators according to a processor subroutine selected in accordance with a host command, sensor signals, and timing information. Another embodiment of the interface apparatus uses voice coil actuators that produce forces in either linear or rotary degrees of freedom using currents applied in a magnetic fields. A friction drive mechanism of the present invention can be coupled between an actuator and a gimbal mechanism. Force from the actuator is transmitted to the gimbal mechanism through frictional contact of members of the friction drive mechanism.

    Abstract: A method and apparatus for interfacing the motion of an object with a digital processing system includes a sensor which has a sensing resolution and detects movement of the object along a degree of freedom. An amount of play less than the sensing resolution exists between the sensor and the object. A passive actuator is coupled to the mechanism to transmit a resistive force to the object along the degree of freedom. A play mechanism is coupled to the actuator to provide a desired amount of play between the actuator and the object along the degree of feedom. The desired amount of play is greater than the sensing resolution of the sensor so that the sensor can detect the desired play when the user moves the object, even when the actuator has locked the object into place. Such desired play can be torsion flex (compliance) or rotary backlash. The actuator and the sensor provide an electromechanical interface between the object and the digital processing system. A gimbal mechanism or slotted yoke mechanism can be coupled between the actuator and the object. The interface is well suited for simulations of medical procedures and simulations in which an object such as a stylus or a joystick is moved and manipulated by the user.

    Abstract: An apparatus and method for simulating a desired response in accordance with an external applied force. The apparatus includes a member which is responsive to the applied force, an actuator coupled to the member for exerting a torque on the member, a force sensor for detecting the applied force, and a torque sensor for detecting the torque exerted by the actuator. Signals from the force sensor are used to determine the system response based upon a desired relation. The force sensor signals also are used to determine the actual system response based upon the physical characteristics of the apparatus. The detected torque is compared with the desired and the actual system response, and as a result of the comparison the torque exerted by the actuator onto the member is adjusted accordingly so that the member performs the desired system response. The actuator is preferably an electric motor so that the apparatus can simulate any desired response, notwithstanding the physical characteristics of the system.

    Abstract: A motion simulator uses an existing personal computer and off the shelf software to physically simulate and control the motions of a computer generated vehicle. The motion simulator is manually powered by the user and includes a control stick connected to an input to the computer whereby movement of the control stick is translated into movement of the computer generated vehicle. A rigid control arm connects the control stick to a base unit and to a cockpit frame to move the cockpit frame relative to the base unit as the control stick is moved. The control stick also contains buttons which provide additional inputs to the computer generated vehicle. Foot operated pedals are also connected to the computer program and to the cockpit to move the cockpit in conjunction with movement of a computer generated vehicle. A throttle lever unit is also connected to the computer to control the computer generated vehicle. The center of gravity of the cockpit is located below the pitch and roll axis so the cockpit tends to return to an initial position. Gravity assists the cockpit and control stick in resisting movement whereby realism is added to the simulation. A trim adjusting wheel moves the seat unit fore and aft to adjust center of gravity of the cockpit frame to position the cockpit frame in a pitch up or pitch down position. A releasable parking mechanism securing the cockpit frame to the base unit immobilizes the simulator for safe boarding. A speaker bracket on the seat unit provides a place to mount stereo speakers for added realism.

    Abstract: A foot operated electrical control is disclosed with simulated aircraft rudder pedals coupled to potentiometers for providing signals to a microcomputer having a flight simulation program. The pedals are additionally linked to one another by slides and a rocker arm for simultaneous pedal travel in opposite directions. The potentiometers may provide cumulative signals determined by pedal displacement or distinct signals when functioning independently of one another. For this latter purpose a carrier block for the rocker arm is positionable out of engagement with the foot pedals. Opposed springs of the control serve to position the pedals in an upright static position. Each pedal is coupled to a potentiometer by spring and pedal biased slides with one of the slides in wiping contact with the pedal.
