SENIOR DESIGN PRESENTATIONS

• Tuesday, 10 May 2005
• 10:30 a.m. to 12:30 p.m.
• Frank Malina Auditorium (Room 124) H.R. Bright Building

Faculty: Dr. Ricardo Gutierrez-Osuna

Time: 10:30am-10:50am
Title: VISUAL SERVOING OF MOBILE ROBOTS
Authors: Paul Corey, John Cox, Brinson Holliday and Bryan Seay

Highlights: An experiment in telepresence. The system consists of a mobile robot with a wireless camera, and a desktop application that tracks head movements of a user with a webcam. The user has a live feed from the robot's camera, and can control the robot by producing different head gestures (e.g., nods and shakes).

Time: 10:50am-11:10am
Title: ROBOT CONTROL WITH BIOSIGNALS
Authors: Jason Black, Drew Gibson, Jeff Johnson and TJ Wittliff

Highlights: An experiment in physiological interfaces. An array of electromyographic (EMG) sensors is used to monitor muscle activity in the forearm of a user. Information from the EMG sensors is passed to a DSP board, which extracts spectral features and performs pattern recognition to determine a robot command from a set of pre-specified gestures. The system performs auto-calibration to learn the physiological conditions of the user.

Time: 11:10am-11:30am
Title: ROBOT NAVIGATION WITH RFID TAGS
Authors: Shaun Lawrence, Chris Moore, Nishant Shah and Chin Yeap

Highlights: An experiment in probabilistic navigation. A mobile robot has been retrofitted with an RFID reader capable of detecting a set of tags deployed in the 5th floor of the Bright building. The robot uses a Monte Carlo navigator (based on particle filters) to maintain a probability distribution of its position by integrating sonar and RFID data.

Time: 11:30am-11:50am
Title: OBJECT TRACKING IN SENSOR NETWORKS
Authors: Cassandra Cotton, Cole Markham, Jim Owsley and Sudhanshu Rajvaidya
Faculty Sponsor: Dr. Dezhen Song

Highlights: An experiment in distributed sensing. A network of motion detectors (N=36 at present) is used to track activity in an indoor environment. Motion events are processed locally and then distributed through the network to track and predict motion trajectories. You can see the actual deployment in the CS faculty mailbox area.

Time: 11:50am-12:10pm
Title: ELECTRONIC TONGUE BASED ON IR ABSORPTION
Authors: Chris Freytag, Rebecca Moehring and James Smith

Highlights: An experiment in chemosensing. An optical sensor system has been developed that is capable of identifying organic compounds (solvents for the moment). The system consists of an IR light source, which is passed through a liquid sample of interest, and an array of narrow-band thermopiles that detect IR absorption at specific wavelengths. Information from the thermopiles is used as a "fingerprint" and passed to a pattern classifier to identify the sample.

Time: 12:10am-12:30pm
