Medieval Wheeled Cannon Kit

This ROKR 3D wooden puzzle contains 158 laser-cut pieces that assemble into a functional medieval cannon model. The kit is rated for ages 14 and up and requires no glue or extra tools to complete. Builders follow an English manual through roughly two hours of construction.

Sustained Play Functionality

Once built the model fires the five included ping-pong balls up to 10 feet using a rubber-band launch mechanism. Adjustable launch angles between 90 and 125 degrees let users experiment with trajectory. Moving wheels allow the cannon to be repositioned by hand between shots.

Thermals Noise and Power Draw

The cannon operates entirely through stored elastic energy so it produces no heat, no noise and draws no electrical power. Wooden components remain at room temperature during repeated firing cycles. The only physical effort comes from manually resetting the catch and trigger.

Questions about this item

Does the cannon generate any noise or heat while it is being used all day?

The wooden cannon is a purely mechanical model with no motor or electronics, so it produces no heat and only the quiet click of the trigger and rubber bands when fired.

What tools or supplies must I already have before starting the build?

No glue or extra tools are required; the box includes laser-cut wood sheets, rubber bands, an English manual and five ping-pong projectiles.

Will the 12.6 x 5.1 x 8.3 in cannon fit on the same shelf as my older ROKR models?

The finished model measures 12.6 by 5.1 by 8.3 inches, so compare those dimensions with your existing shelf space to confirm it will sit alongside earlier kits.
