KSJP12: Off-the-Shelf Distributed Robots (COTS-BOTS)

Sarah Bergbreiter

The goal of the CotsBots project is to use commercial off-the-shelf (COTS) components to build and deploy inexpensive and modular robots, which can be used to investigate algorithms and cooperation in large (>50) robot networks. Distributed robot networks have applications ranging from mapping and exploration to constructing complex systems. Work in BSAC is targeted towards providing a standard robot platform with a variety of modular sensor and actuator boards to test algorithms to solve these problems. In addition, we would like to explore the development of sensors that would...

KSJP23: Steered Agile Laser Transmitter (SALT)

Our goal is to create an efficient system-level analysis tool for the simulation and design of complex MEMS. The program is to be readily accessible, easy to use and extend, and capable of giving speedy results for complex systems, including static, steady-state, transient, sensitivity, and bifurcation analysis results. We will also support higher-level programs for design optimization and synthesis. We will incorporate state-of-the-art numerical libraries, as well as integrating new numerical techniques, such as improved model reduction methods. We will also build software to...

KSJP29/JD: Floating Electro Mechanical Systems (FLEMS)

KSJP33a: Tools for Microassembly

Subramaniam Venkatraman

Complex three dimensional micromechanical systems can be built using multi-layer MEMS processes. There is however a tradeoff available between process complexity and post-fabrication complexity (assembly operations). In this project, we fabricate sockets, connectors and the tools to pick up and rotate them using a single mask Silicon-on-Insulator (SOI) process. We then use pick and place assembly to create complex mechanical micro-systems which are difficult to realize with conventional fabrication techniques.

KSJP32: Incremental Network Programming

Jaein Jeong

We present an incremental network programming mechanism which reprograms wireless sensors quickly by transmitting the incremental changes for the new program version.

Project end date: 09/08/05

KSJP33: Silicon on Insulator Microassembly

Subramaniam Venkatraman

To develop actuated 2-axis micromirrors and walking microrobots using a pick-and-place assembly process. Simple fabrication processes have a high fabrication yield and quicker design cycles than complex processes. The quest to minimize process complexity has led us to a single-mask Deep Reactive Ion Etch (DRIE) using Silicon on Insulator (SOI) wafers. After release, these parts are broken free from the device layer of the SOI wafer using grippers fabricated in the same single-mask process, rotated 90 degrees out-of-plane, and then assembled with other parts (figure 1). With this...

BPN348: Subterranean Wireless Sensor Network

Valerie Zimmer
Michelle Ma

Our long term goal is to prototype and evaluate a reliable, self-healing wireless mesh sensor network for use in mines, caves, and underground storage facilities. Its primary application will be to monitor the physical environment, such as temperature, humidity and barometric pressure, as well as detection of potentially hazardous gases such as carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4). We will evaluate the feasibility of using real-time wireless sensor networks to monitor operating environments and to provide hazard identification and warning. An important aspect...

BPN347: Smart Flea

Subramaniam Venkatraman

Behavior monitoring of animals is of interest to pharmaceutical firms which perform animal testing during the development of drugs. Behavior monitoring using a wireless accelerometer strapped to the animal is explored in this project. Since rats are the animal used in this study, it is essential that the wireless accelerometer meet some stringent weight and size requirements. A prototype wireless accelerometer has been developed which comprises of a 3-axes accelerometer, wireless transceiver, microcontroller, voltage regulator, switch, antenna and battery. It weighs 10.2 grams and is...
