Looks great, as well as the
rest of the robot, but I have a few questions - not sure if I completely understood your system.
Are the gas shocks preloaded, and then released to lift (launch?

) another robot? If that's the case, how hard is it to load them? Lifting a 150 pound robot 14" up in two seconds sure requires a lot of force.
Also, does the entire system pivot around that huge C-bracket?
Anyway, your robot sure looks great. It seems like we are using the same material on our ramps (does it, by any chance, weigh 1,5 kg per square meter? Incredibly strong stuff!

)
