The prompt
This is an autonomous, four-wheeled competition robot featuring a sturdy metal frame and a low, wide chassis. Two parallel, vertical metal rails mounted atop the chassis form a lifting system. A sliding carriage travels along these rails—driven by a gear motor via a belt or cable-and-pulley arrangement—and is equipped with a two-jaw mechanical gripper capable of opening and closing to grasp boxes. The gripper assembly can traverse the full height of the rails, allowing it to pick up and place boxes at various levels. With its array of wiring, control circuits, and motors mounted on the frame, the robot embodies a pragmatic, student-competition style of design that prioritizes structural robustness and load-lifting capability.
