Position Tracking System
A position tracking system includes an infrared-sensitive device, such as an infrared camera that generates signals in response to detected infrared light in a field of view of the infrared-sensitive device. A processor is responsive to the signals generated by the infrared-sensitive device for determining a position of the detected infrared light. The processor also generates tilt and pan signals based on the position of the detected infrared light. A tilt and pan mechanism moves a visible-light video camera in response to the tilt and pan signals from the processor. The active infrared light-emitting device includes a loop having at least two infrared light-emitting elements disposed along the loop, on opposite sides of the loop. A control box is disposed in the loop and is in electrical communication with the infrared light-emitting elements. When the loop is disposed around an object that rotates relative to the infrared-sensitive device, a constantly unimpeded viewing channel is provided between the infrared-sensitive device and at least one of the elements due to the positioning of the elements. The position information obtained from the infrared-sensitive device is used to direct a visible-light camera to track the active infrared light-emitting device in a manner similar to that performed by a human camera operator.
Portable Robotic Device
A portable robotic device (PRD) as well as related devices and methods are described herein. The PRD includes a 3-D imaging sensor configured to acquire corresponding intensity data frames and range data frames of the environment. An imaging processing module configured to identify a matched feature in the intensity data frames, obtain sets of 3-D coordinates representing the matched feature in the range data frames, and determine a pose change of the PRD based on the 3-D coordinates; and perform 3-D data segmentation of the range data frames to extract planar surfaces.

NRI: Collaborative Research: Quadrupedal Human-Assistive Robotic Platform (Q-HARP)
The objective of the project is to develop a novel quadrupedal human-assistive robotic platform. The compact and lightweight robot will actuated by high-power-density chmo-fluidic actuators and guided by a 3D computer vision system, which also provides a contactless interface for human-robot interaction.
