Robots that I have built and worked with over the years.

My current work at CoroWare allows me to play with the CoroBot. And the ClassPack provides an accurate simulated version of the robot.

  I interned for Microsoft and worked with the Microsoft Robotics Developer Studio team. I contributed mostly to the fischertechnik and Lego NXT services. I continue to work with RDS on many projects. Here are some of my add-ons.

  Georgia Tech's entry in the RoboCup Rescue 2007 competition was my master's project. Click here for more pics and videos. At 300 pounds, it was the largest competitor by far. Unfortunately, the size of the robot and low ground clearance prevented the robot from exploring much of the arena. I designed and machined almost the entire robot myself. I also did quite a bit of systems integration. Our goal was to have better video throughput by using 3 orthogonal radio frequencies as detailed in this paper:

Ben Axelrod, and Can Envarli. (RCom) Reliable Communications for Teleoperated Rescue Robots.

  The goal for this project was to get this Kuka arm on a Segway RMP to serve coffee. Details in this paper:

My team chose to use Microsoft Robotics Studio as our base platform. I was responsible for the overall service architecture.

During a summer internship at Iguana Robotics, Inc. I had the opportunity to help design and build a few new robot platforms:

Marilyn - The first robot I helped design at Iguana during my internship.  I did about half of the mechanical design on the first iteration of Marilyn.  

TomCat - The second robot I helped design during my internship.  I had a much larger role in designing this robot than Marilyn.  After I came back to Iguana to work full time, I extended this robot with another motor in the torso.

Snappy - Although I did not design this robot, I designed and built the sensor and power system.  This included a rack mount box with the motor controllers and power supplies.  It also included an intermediate sensor consolidation circuit board that fits discretely inside the torso of Snappy.

I was the team leader of my senior design project in which we built an eight legged hobby servo driven robot.  Here is a brief report about our work and the robot.  And here is a full size picture.

Cyclops - A one eyed photovore. I built it with Lego motors because they are powerful and easy to work with.

I made these robots in high-school and early college.

 Legs - A hexapod walker.  July 1999 Lego Mindstorms Novice Hall of Fame winner.

 Smart-Turn Bot - Basically just a bumper bot, but with rack-and-pinion steering and the ability to sense when the wheels are straight.  December 2000 Lego Mindstorms Novice Hall of Fame winner.

 Robo Snake - A five segmented snake with home built red LED eyes.

 Robotnik - Another bumper bot, but with home built infrared proximity detectors and four wheel steering.

Maze Bot - A robot that can solve a simple maze.

These are some of my home made Lego sensors.

Accelerometer - A simple pendulum, one axis accelerometer.

Keyboard - 12 buttons in 1 sensor port.

IRPD - An infrared proximity detector.
