Deep-Sea Mechanical Pendulum

The ROKR Deep-Sea Adventurer MCD04 is a laser-cut wooden model that assembles into a gravity-powered pendulum submarine. It is designed for hobbyists aged 14 and older who enjoy hands-on construction and kinetic display pieces.

Build Requirements and Display Freedom

Assembly uses 219 precision-cut pieces and requires no batteries, glue or external power to operate. A moderate 2/5 difficulty rating and roughly three-hour build time suit both newcomers and experienced builders looking for a self-contained project.

Capacity and Operational Limits

Once completed, a gentle nudge sets the submarine swinging along its track to demonstrate pendulum motion continuously. The kit provides a single mechanical movement with no motorised functions, lighting or programmable features beyond the physical swing.

Questions about this item

How long does the pendulum swing after a single push before it stops?

The gravity-powered motion continues until friction and air resistance dissipate the kinetic energy, so run time varies with the strength of the initial nudge.

Does the model generate noticeable noise or heat during continuous display?

The wooden pendulum operates silently and produces no heat because it has no motor, electronics or power source.

Are any tools, glue or batteries required to complete the 219-piece kit?

No extra items are needed; the laser-cut wooden pieces interlock without glue and the motion is purely mechanical.
