Wow! nice arm guys. With three joints, how do you guys program it? One joystick axis for each joint? Or did you guys write a program to have the arm follow a set path?

It can pick up from the floor however we prefer to take tubes from over the wall because it is faster.

How do you control all the joints?

Re: pic: RoboRaider-2007
 

The bottom two joints are driven by the same motor and controlled by the Y- axis of the left joystick. The third arm segment is controlled with the Y- axis of the right joystick. The grabber open and close and the wrist motion are controlled with the buttons on each joystick. The turret is controlled by the X- axis of the right joystick. The box contains the activation for our presets which will move the arm to a previously stored position. We have 4 presets for load positions and 6 for putting tubes on the rack (2 positions for each height). The presets can be overridden at any time by moving the joysticks. It may seem complicated but it’s actually fairly easy to control. When we place tubes on the rack I usually use the preset to get close then override it to finish lining it up.

Congratulations on the good work guys!

The time we had with some of you here in Brazil was awesome! Looking forward to seeing you again, and good luck in Atlanta!

Have you had any issues with being top heavy/ getting knocked by other robots? Otherwise than that, it's an amazing design.

We have a very low center of Gravity with the arm descended. We have a high rate of speed to escape. We haven't been upended in the regional.

no thats not it
my strategy is completely legal

but im not going to give all the other teams an advantage

the other defensive robots are just gonna have to figure that out on their own

It looks like a DRAGON!

Re: pic: RoboRaider-2007
 

Does it have a name? Or are we back to calling all the robots The RoboRaider?

Re: pic: RoboRaider-2007
 

We to take tubes from the slot, and find it very fast compared to taking off the floor...
