• STEM lessons and classroom demonstrations on mechanics and renewable energy
• Home science projects and guided learning activities
• Hands-on workshops teaching basic robotics and assembly techniques
• Eco-themed experiments comparing solar and battery power performance

Key specifications

• Approximate assembled dimensions: 20.5 cm x 27.5 cm x 6 cm
• Power options: solar panel drive and battery drive
• Type: educational DIY rover robot kit for assembly
• Suitable age range: beginner learners and children (adult supervision recommended for younger users)
• Focus areas: basic mechanics, simple electronics, mobility experiments, eco-energy concepts

How to use

Follow the included assembly instructions to build the rover step by step, connecting mechanical components and the drive system. Install the solar panel and test movement in sunlight; if sunlight is insufficient, install batteries in the designated compartment to power the rover. Use the kit to test how different light levels and surface types affect movement, and repeat assembly or adjustments as part of learning exercises.

Recommendations

Use the rover on flat, even surfaces for optimal movement and test it outdoors in daylight to observe solar operation. When using batteries, follow the battery safety and disposal guidelines. Supervise younger builders during assembly and when handling small parts or batteries.
