How to use it
- Carefully punch out the plastic components from the frames using the provided tool.
- Select one of the eight robot designs from the 48-page colour manual.
- Assemble the gearbox and solar motor unit according to the diagrams.
- Connect the mechanical legs or wheels to the central chassis.
- Place the robot in direct sunlight or under a 50W halogen bulb to activate.
- Experiment with different angles of light to observe changes in speed.
Pro tip
Solar panels require direct sunlight to work effectively; if testing indoors in the UK, use a high-wattage incandescent or halogen bulb held close to the panel, as standard LED energy-saving bulbs often lack the necessary light spectrum.
This kit has been praised for its clear instructions, reviewed by Which? (2023) as a top choice for educational toys. Furthermore, per Ethical Consumer's 2024 guidance on sustainable toys, the brand's move toward plastic-free packaging significantly boosts its environmental standing compared to mass-market competitors.
FAQ
Does it work on cloudy days in the UK?
It depends on the cloud density. While the high-efficiency solar cell is sensitive, thick UK cloud cover may not provide enough energy for the motor to turn mechanical gears; for consistent indoor play, a bright desk lamp is recommended.
Are the parts compatible with other kits?
Yes, the components are designed to be part of the wider Thames & Kosmos physics range. While they aren't compatible with LEGO, they can be integrated with other 'Science Discovery' kits from the same brand to build larger custom solar machines.
Is there any soldering or glue required?
No, this is a completely tool-free assembly process. All parts are designed to snap together securely, making it safe for younger children and ensuring that the models can be taken apart and rebuilt into different configurations easily.

How to choose toys & games
Choose an age-appropriate toy that fits the child's interests and the space available. Replay value, replaceable parts and ease of storage matter more than the number of pieces in a box.
| Check before buying | Why it matters | Trade-off or limit |
|---|---|---|
| Age grading and hazards | Read small-part, magnet and battery warnings and supervision requirements. | An educational claim does not override the stated age restriction. |
| Replay value and compatibility | Check whether it works with existing sets and supports repeat play. | A specialist expansion may require a base set you do not own. |
| Storage and replacements | Check spare pieces, washable parts and battery or subscription needs. | A low initial price can hide recurring costs. |
Common mistake: Wooden or recycled construction is not a substitute for checking the exact toy's safety information.
