It's shot with pneumatics and if you include the motor, winching system, and the solenoid, the whole system can weigh under 3 pounds. If you have any questions about this feel free to ask and I have some pictures of it here: https://docs.google.com/presentation...it?usp=sharing

Woah. That's awesome. It's like a piston, but the extender is the hook. I like that 95% success rate (don't know what the sample size is, though) but it seems a little surprising with that hook design. I would expect it to fall off easily. Do you have video of you testing it?

Edit: Just read the line "Hook is made to rebound off the slant behind the hook on the tower to then be pulled back and grab on." This seems more feasible for the hook design.

Sample size is out of 40. The idea behind it is the round bar near the base causes it to rotate towards the heavy side (The hook) when getting pulled over. It seems to work nearly 100% of the time if you go slowly. But even when pulled quickly it has a tenancy to bounce off of the tower and center itself onto the bar. The margin of error is pretty big especially when it is shot up close to the wall so even if it hits lower down on the tower it has enough power to ricochet off the slope and over the bar.
