4M Toysmith, Green Science Salt Water Powered Robot Kit, STEAM Powered Kids, Beach Toy, For Boys & Girls 5+

Q: What kind of functions develop this robot? What does it do?

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?

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?

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.

It will work multiple times. Make sure after each use to clean the battery parts with water and allow to dry before reassembling
