A Neuroprostetic Device To Control Postural

Equilibrium In Spinal-Cord Injured Dogs

In this work we look at how to help dogs like poor Lilly, who has a

 spinal chord injury.  First, we built our own Dancin'Dog , in order to develop and test walking gaits.  We use sensors to allow us to provide HipBalancing for the dog. Finally, we will install electrical sensors in order to implement this in a biological specimen.

Large Scale Haptics

The use of haptic devices in an immersive environment has been widely accepted as increasing the immersive experience of a user in a virtual environment. In this work we place a commonly used, commercial haptic device on a planar mobile base to expand the useable workspace, and explore the fidelity of virtual forces as the human interacts with the environment.  Experimental results show that the transparency and effective environmental impedance is governed by the characteristics of the commercial device and is not appreciably affected by motion of the base during contact with the environment.

Inertial Stabilization and Navigation

Tracking a target from a moving platform is a problem that has relevance in military, aviation, and space applications.  We develop a method for tracking a target using a platform-based antenna.  We use the steepest descent gradient direction to minimize the value of a cost function to obtain optimal performance of the system in real time.

Design, Development, and Testing of an Automatic Window Shade Controller

We design an active window shade to control the direct solar gain through a window.  Using simple actuation hardware and sensors, a control strategy is presented that automatically adjusts window shades to save HVAC energy by controlling direct solar radiation passing through a window
