## Questions & Answers

**Q: What kind of functions develop this robot? What does it do?**
A: It goes forward.  That is it.   It took my son and I about 10 minutes to build it, and it ran for about 30 minutes before the battery need to be cleaned, and rebuilt.

**Q: How many watts is the LED lightbulb?**
A: The power depends how fast you spin the windmill.The forward voltage drop of an LED is typically 2 to 3 V. Let's say 2.5V.A current of 20 mA (0.02A) will produce a bright light. That's probably close to what you get with a fairly strong wind turning your windmill.The power dissipated in the LED in this case is 2.5 x 0.02 = 0.05W = 50 mW.

**Q: Is included the elements, for example charcoal, aluminium or salt? And is included some pieces of science kit as tube, ect?**
A: It a simple kit,  included small slides aluminum, carbon, works fine but is small,  from kids 4 old years. Needs salt and water not included in the box.

**Q: Does this only work once? My son can't get it to go a second time. Wondering what to do.**
A: It will work multiple times. Make sure after each use to clean the battery parts with water and allow to dry before reassembling
