Triplot

My robot is going to collect dirt using a crane. The crane is going to be in the back of my robot and have its own indent in the back to fit the crane snuggly inside. When it needs to pick something up, the crane will go from the back and wrap around to the front to pick things up. The crane will have a collapsing design where it extends depth wise and is able to pick up a lot of dirt. When it is done using the crane the bottom will close on itself and become smaller. When encountering the Luna dust, the cranes inside are going to be black and just a little sticky so it can attract the Luna dust.
