What This Kit Is

The Smartivity Robotic Mechanical Hand is a screen-free STEM construction set made from engineered wood. It is designed for children aged eight to fourteen and measures thirty centimetres by twenty-five centimetres by nineteen centimetres. The kit weighs point two five kilograms and includes one hundred twenty pieces that assemble into a working mechanical hand.

What It Replaces

This kit replaces passive screen time with a hands-on building project rated at a medium DIY level. The step-by-step manual guides the builder through the assembly process, and a lifetime supply of replacement parts is included so a lost or broken piece does not end the activity. The jump is worth it when a family wants a durable, reusable model that teaches mechanical principles without batteries.

Who It Suits

The set suits curious boys and girls who enjoy building moving models and learning how levers and linkages create motion. It also suits gift-givers looking for an award-winning toy recognised in thirty-three countries. It is not for buyers who want a motorised or programmable robot, nor for children younger than eight who need a simpler build.

Questions about this item

How much space does the 30 cm by 25 cm by 19 cm assembled hand need on a table?

The finished model occupies a footprint of 30 cm by 25 cm and stands 19 cm tall, so allow at least that much clear surface area.

Which step in the manual do builders most often skip when assembling the finger joints?

Builders often rush the tendon threading through each finger joint; follow the manual sequence exactly and test each finger before moving to the next.

How do I get replacement wooden pieces if one breaks after the 120-part build?

The manufacturer provides a lifetime supply of free replacement parts; contact them directly with the part number from the manual.
