Method and apparatus for realtime remote robotics command
First Claim
1. An apparatus for controlling a device, the apparatus being arranged to be at least partially supported on and operated by a human appendage, the apparatus further being arranged to transmit signals to and receive signals from the device, the apparatus comprising:
- a positioning assembly substantially mounted on the human appendage, the positioning assembly for responding to motions of the human appendage, the positioning assembly further transmitting position signals to the device to control the device, wherein the positioning assembly includes a spring arranged to extend in response to the motions of the human appendage;
a braking assembly for resisting motion of the positioning assembly, the braking assembly being coupled to the positioning assembly, the braking assembly being responsive to resistance signals received from the device, the resistance signals being substantially indicative of a force that is transmitted to the device wherein the braking assembly includes a brake, the brake being arranged to prevent the spring from extending in response to the resistance signals received from the devices, and a solenoid, the solenoid being arranged to activate the brake in response to the resistance signals received from the device, wherein the solenoid is in communication with the device; and
a sensing assembly for transforming haptic signals received from the device into sensations felt by the human appendage, the sensing assembly being coupled to the positioning assembly.

Abstract
Methods and apparatus for controlling a remote device using a command glove system are disclosed. An apparatus for controlling a device is arranged to be at least partially supported on and operated by a human appendage. The apparatus is further arranged to transmit signals to and receive signals from the device, and includes a positioning assembly mounted on the human appendage. The positioning assembly is arranged to respond to motions of the human appendage, and also transmits position signals that are used to control the device. The apparatus includes a braking assembly which is arranged to resist motion of the positioning assembly, and responds to resistance signals received from the device. The apparatus also includes a sense effecting assembly which transforms haptic signals received from the device into sensations felt by the human appendage.
