Great science projects for kids: This solar robot includes gears, screws, solar panels and other building parts. Through assembly practice, it helps children learn the mechanical transmission structure of the vehicle model and how solar energy is converted into mechanical energy. It is a perfect STEM building toy for boys and girls ages 8-12.
DIY building block assembly.
The solar upgrade version has two sports modes that can be switched: one needs to be powered by R6/AA/UM3 battery and the other is powered by solar panels.
This is a four-wheel drive device model, which can use the vertically moving wheels at the four corners to move forward and can easily overcome 50mm high obstacles.
All materials needed for simple snap-on or bolt-on assembly are included. Simple wiring is required to complete assembly.
3 types of chassis angles can be selected when setting up.
