Industrial Robot Arm Becomes Giant Catapult

wintersynth brings us a story about a group of enthusiasts who made a catapult out of a 2,800lb industrial robot arm. They used it to launch bowling balls, fireballs, and cans of beer toward a stationary target, and they controlled the catapult's aim with a graphical UI on a laptop. "I wanted to be able to control the rotation of the robot so we could aim the robot from the laptop, but I quickly realized that since the desert is so flat, we could do some basic ranging on the target too. I also wanted the targeting to be overlaid in 3d over a photograph of the target area. The software needed to control the robot like an MMO or RTS game. I suspect that video games, in general, have some of the most optimal control interfaces. I wanted to try a control scheme similar to the area effect spell targeting in World of Warcraft."

      The right to bare arms does not give you the right to have nuclear warheads No, but it does give people the right to wear hideous hawaiian shirts, which is almost as bad.

    It's not a real catapult unless it's flinging cows or pianos.

    Let me get this straight... they "Rented" the camera by buying it at Fry's and returning it?

    I'm sure some people will defend this tactic, but its stuff like this that causes awesome return policies at stores to be restricted, and prices to go up. (as recently happened at CostCo)

    Yeah, I was pissed at them when I read this too. I hope that when Fry institutes a 20% open-box charge on returns, that everybody look this guy up and send him a thank you note. Wrapped around a bowling ball.

    Indeed, source code for the robot states that correctly.
