One of several Mini-Sumos.

This bot uses custom machined wheels, copies of 'Bio Hazard.'

Bots come in all shapes. This is exploring T-time, a T-shaped course.

Speaking of shapes, this is the 'Copper Pyramid', made of PCB copper clad.

This bot won the DaVinci award for being artistic!

DaVinci bot trying to escape from the contest!!!

This bot eventually won the _FRIED_ award!

Fried bot in action - chase that line.

An 18 Servo Hexapod. Perhaps the slowest moving, but very interesting.

The IsoPod is a DSP controller from New Micros Inc, Dallas, TX.

A bot featuring the IsoPod.

There were several Lego(tm) bots present.

This Lego(tm) bot is a line follower.

A group of the more colorful robots.

A line follower built with surplus motors.

Another line follower waiting it's turn.

This bot is doing some wall following in the T-time course. It has a handle to make it easier to catch!

Close up of the machined Hexapod leg mechanics.

DaVinci used a Mac ejector motor as the driving force.

Another Mini Sumo.

The rear view.

This Mini Sumo uses the OOPic chip - object oriented.

Now I've seen a rat's nest, but where's the rat?

A smaller photogenic group.

This bot had ultrasonic (under plate) and IR sensors that rotate 90 degrees.

This 'sandwich bot' is built in a plastic sandwich box.

This bot uses scooter tires for grip.

Another view of the Sharp IR sensors. These determine distance through triangulation.

A Mini Sump featuring the IsoPod and urethane tires for better grip!

This bot uses a Tamiya(tm) gearbox.

RoboRama is sponsered by the Dallas Personal Robot Group. I believe they hold this type of contest twice a year. One contest includes line following, T-time (exploring a T-shaped course), there and back (exploring a rectangular course), and Can-Can (retrieving white soda cans). The second contest includes Mini Sumo (find and push the other bot out of a 30-inch ring) and table top contests. More information is available on their web site at Dallas Personal Robotics Group.
