|LEGO → System → Space → Life on Mars|
The Worker Robot is the smallest Life on Mars robots. It is a small square with a spot where the martian sits and from which a control panel extends. It has 2 legs and feet. The set is mostly Brown and Tan with some Dark Gray. The last page of the instruction shows the names of 7 martians, though, oddly it does not show the name of the martian piloting the robot. It also shows BB in the corner.
