Exemplary Production of Acetylene with Calcium

The operation involves a water reaction to calcium carbide to produce acetylene gas. When the gas is kindled, the robot launches into the air via a jet of water and combustion products. The robot can also glide through the air, extending its maximum range to 26 meters. It can carry enough fuel for 10 consecutive launches; when it lands, the chamber begins to refill until it reaches its optimal launch
