1. Basic tricks of making robots for your kids

make a hygrometer Robot for kids

• Attach two thermometers back to back with carpenter's glue. If the thermometers have plastic backings, use epoxy glue instead of carpenter's glue.
• Allow glue to dry.
• Drill a hole through the two thermometers at the top of the mountings.
• Drill a hole at the wooden dowel's top.
• Attach the thermometers to the dowel with a 1.5 inch (3.75 cm) wood screw, placing the washer between screw and dowel. Do not tighten the screw all the way. The thermometers should swing freely around.
• always make a special out frame for this
• A toy "Robot tank"
  You will need a wooden cotton reel, a small wood saw, a large rubber band about 100-120 mm in circumference, a stick or pencil about 10-15 cm long, a small (shorter than reel diameter) nail, and a slice from the base of a candle with a hole in the center.

  What you do:
  This is an old traditional children's toy that still fascinates. Use a tenon saw or similar to cut a V-shaped groove across the center of one end of the reel, then thread the rubber band through the hole in the reel. Slip the nail through the rubber band and settle it into the slot. Slip the candle slice over the rubber band at the other end, and put the stick through the rubber band. Wind the stick around until the rubber band is quite tight, then put the cotton reel down and watch it run.

  • Measuring electricity .hand made robot.
    This is a simple gadget to detect electricity when it flows.
    You have a matchbox tray, a long piece of fine enameled copper wire, and a compass. Put the compass in the matchbox tray, coil the wire gently around the tray, always going in the same direction, and put it on a table, with the compass needle parallel to the coils of wire. When a current goes through the wire, it makes a small magnetic field, which may be able to make the compass needle twit.
  • Making a Leyden jar .hand made things.
    You will need a foam ("disposable") cup, some aluminum foil, and an insulating surface. Wrap the inside and the outside of the foam cup with aluminum foil, but keep the two covers from touching each other. Leave a small "tag" of aluminum foil on the outside to allow "earthing" for charging by induction. This involves charging a rod, placing it inside the cup (not touching the aluminum!) and then touching the outside foil by way of the tag. Take your hand away, and then remove the rod: the cup is now charged.
