Planchette Spector is a pre-made future Sim living in Oasis Landing, from The Sims 3: Into the Future. He is implied to be an adventurous Sim who is desperate to open the door to the crashed ship, but never succeeded, which caused him to go into a mental breakdown. He lives with his Plumbot 5P1R17 and is good friends with her.
His name comes from the planchette used with the ouija board, used to contact ghost. Planchette was brought back from the dead so that's why the name makes sense.
