Small least:
- The initial drop parts of their support is a bit tedious especially the fact to ensure that no remaining pieces of plastic from the media (step necessary to prevent moving parts from locking during startup ).
- Energy dependence: you need a good light source (sunlight or close proximity to a 50W lamp)
- Velocity: on some more speed montages bring more fun (the motor is tiny probably limited by the dimensions of the kit and the solar panel).
Educational:
- Introduction to the manual assembly,
- Introduction to solar in particular by the panel orientation,
- Initiation to transfer driving force (gears, form parts)
- Develops attention, dexterity and organizational skills.
It is hoped a future extensible model: battery, ultrasound sensor, remote control, moving any direction, vocal learning, camera, ... an opening to electronics / home automation easy and free (Arduino, pcduino and variants)
