-The submarine contains 3 motors - left and right side propulsion motors, and a dive/​surface motor. ​ There is a forward facing camera and two white LED illumination lamps. ​ On the top there is a power switch ​and red/green status ​lights, and on the sides there are infrared ​receivers.  Both electronics and motors are powered by a single pair of 1.5V AA cells.+The submarine contains 3 motors - left and right side propulsion motors, and a dive/​surface motor. ​ There is a forward facing camera and two white LED illumination lamps. ​ On the top there is a power switchred/green status ​light, and an infrared ​receiver.  Both electronics and motors are powered by a single pair of 1.5V AA cells.

 +The outer plastic ​hull is secured ​by six screws, two holding the front and four holding the top and bottom halves together. ​ The screw heads need a triangle 2.0 screw driver blade. ​ The inner plastic hull is held together by six philips head screws and silicon sealant rings on both ends.   The battery cover seals against the rear silicon ring.

 + 
 +Inside the inner hull there are two double sided circuit boards. ​ The top, smaller, one ("​82418-RX-B"​) contains the on/off switch, infrared receiver and bi-coloured status led.  The illumination LEDs and three motors connect directly to this board. ​ There is a 6-way ribbon cable connecting it to the larger logic board underneath.  
 + 
 +The camera, USB socket and battery connect directly to the second board which contains a large IC on the top (PMS306416B 64Mbit, Synchronous Dynamic RAM) and another large chip on the underside.

 +The 82418-RX-B board has an epoxy covered controller chip (labelled 80423) on the underside and on top there are three 8-pin chips (MX608E motor controllers) and a 47uF, 10V capacitor.
