Magikarp's frame was designed on a small budget. It is made of waterjetted polycarbonate sheets with t-slot aluminum rails for structure. Magikarp has two 4" acrylic waterproof enclosures: the bottom enclosure houses the battery and camera, while the top enclosure houses the electronics. The bottom enclosure features a clear dome endcap for the camera, and all other endcaps have penetrators for feeding through wires for peripherals.
Magikarp did not have any actuated systems, and was thus incapable of completing the claw, torpedo, and dropper tasks.
