Mini Engineer – 120+ STEM Projects Lab Kit

Mechanical • Electronics • Motors • Simple Machines

The Mini Engineer STEM Projects Lab Kit by Thinking Robot is designed for children who learn best by building, experimenting and taking things apart.

Instead of giving the learner one fixed model to assemble once, the Mini Engineer kit combines motors, wheels, pulleys, switches, LEDs, magnets, sensors, wires and mechanical parts into one reusable STEM laboratory.

Children can use the same components again and again to explore mechanics, electricity, motion, light, magnetism, simple machines and basic electronics through more than 120 project ideas, experiments and challenges.

120+ Projects & Experiments

The Mini Engineer Kit is not limited to one robot or one circuit.

The same collection of components can be combined in different ways to create:

• Mechanical builds
• Motor experiments
• Simple machines
• Pulley systems
• Wheel and axle experiments
• Magnet experiments
• LED circuits
• Light-sensing circuits
• Buzzer circuits
• Push-button circuits
• Switch-controlled circuits
• Motor-direction experiments
• Solar-energy experiments
• Propeller experiments
• Basic transistor circuits
• Creative STEM challenges

This gives the learner room to move from following instructions to experimenting independently and inventing their own builds.

Built to Be Reused

Unlike a single-use project kit, the Mini Engineer kit is designed around reusable parts.

Build a car today.

Turn the same motors into a pulley system tomorrow.

Use the switches for an alarm.

Use the LEDs and breadboard for circuit experiments.

Then combine components to invent something completely new.

That is the core idea behind the Mini Engineer STEM Lab.
