A great project made for Cambo Industries Greece.
The purpose is for users/players login to theirs' facebook accounts, and play the application so they can win many presents.
The system consist of an application (facebook app) and a hardςare system something like a big CNC machine. From withing the application the players watch what happens inside a big box (2X4X2 meters) and they control a mechanical gripper, so they collect clothes that are on the floor, and had to put them inside a smaller box in the middle of the big box.
The game was on for about 3 weeks, with thousens player trying to score.
After all it was a big success with a lots of presents for the people who participate the game.
Special thanks to:
The Construction phase !!!
First I had to make a plan, about the mechanism which pickup the clothes. Small hobby robotics grippers failed after a few attemps so I had to come up with a bigger more relaible gripper. I used one linear actuator from Pololu and after I machined a couple of POM parts I made this gripper
I also put limit switches at the closing point not to brake anything.
Then was the BOX, the big and the small one
here are a few steps from the construction:
The BOX part 1
The BOX part 2 Installing the bridge
It was a little tricky to find the correct way to move the bridge, with out friction, regarding the weight which was more than 20Kgr
and a family photo during the build :)
Big Box Ready
The smaller box which will hold the clothes with some lighting effects.
I also position an IR sensor on the smaller box to keep track if the clothes actualy droped inside it.
For controllers I used standard CNC drivers with NEMA 24 Steppers, Great stuff
The Driver for the step motors
and the 3 of them
