I just got back yesterday from the Virginia TSA state competition and I was surprised at just how much Vex hardware was being used there as control technology. My project was an animatronic hand which I will be posting a full youtube video of this weekend (its very cool). It ended up taking 2nd in the state because it was well downright awesome (we lost to an animatronic penguin ERRRRR!!!).
Here is a quick picture of my project, it is an older one and the project has since become smaller and more compact along with some additional hardware.

The first picture is of the guys who got 3rd place which I had thought was my only real competition.

They built a robotic bartender and it was based off mostly Vex hardware and components. In this picture you can see that the claw is composed of a vex servo and metal parts, and you can see a vex bumber. If you look into the head area you can also see another motor/servo.

Underneath there is a large amount of vex hardware interfaced with a non vex metal gearmotor which I thought was very cool. It allows the bar tender to slide left and right on the tracks about 1ft in each direction.
This was a cool project but they didn’t win 1st or 2nd because they were having technical problems getting the audio to play and other small things kept happening. Though one thing about this design was very bad they wrote a java program on the computer to play audio files then mounted a motor over the keyboard to push a key to signal the audio to play. This worked but the audio was out of sync. Wouldn’t it have been easier to spend a little bit of time and get a serial connection working? Once they saw how much was in my project they immediately said dang I wish you were on my team. Though unfortunately we can’t as we don’t attend the same school.
There were other things that were based on vex as well such as these two robots which were pretty cool.
