WHAT IS SOLAR ENERGY•Solar energy is radiant light and heat from the sun harnessed using a range from the sun of ever- evolving technologies such as solar heating , solar photovoltaics , solar thermal energy , solar architecture and artificial photosynthesis.

ABOUT ARE PROJECT 1We choose our topic as Solar energy.2All of us made a solar panel and a beetlebot robot.3Now time to show how we made our solar panel and our beetlebot robot.

MATERIAL REQUIRED • FOR SOLAR PANEL• CD-COVER• COPPER SHEETMIXTURE OF HOT SALT WATER• INSULATOR WIRE• SILICON GLUE

• FOR BEETLEBOT ROB0T • Two small motors• Two lever switch • Two doubled battery holder• Small beads , paper clip• Heat shrink tube• Spade connectors• Metal piece• Hot glue• Soldering machine • Soldering iron

HOW WE MADE SOLAR PANEL• First we took a copper sheet and burned it For 30 minutes and kept it for 30 minutes to cool down and then we rub copper sheet with sand paper so that copper sheet should be reddish.• Again we took a copper sheet and cut it in a U shape and we pasted the copper sheet on the one side of cd –cover with the help of silicon glue. Now we pasted the burned copper sheet on the same side of cd- cover. Now with the help of soldering machine we soldered insulator wire to copper sheet which we will connect to robot.• Now we putted mixture of hot salt water(hot water +salt)and we closed cd- cover with silicon glue .

HOW WE MADE BEETLEBOT ROBOT•

We fitted the heat-shrink tubing to the wheel on the original motor. We Cutted a piece of the tubing just a little longer than each wheel, we fitted into the wheel and we shrinked it using a lighter.• We glued the switches to the backside of the battery holder. We glued the switches to the back end of the battery holder on the flat side. This should be the end which the wires come out of. We placed them at an angle in the corners, such that the contacts farthest from where the lever-looking metal bar goes into the device are touching at the center line of the device. The levers, which are the switches themselves, should be at the outside, near the wires.

We Placed the metal strip. We Placed the 1”x3” strip of aluminum just behind the switches, center it, and then we bended the excess down at a 45° angle. We Glued it in place with hot glue. Let it set completely before moving on. We Attached motors to the metal wings. Using hot glue, we attached the motors to the bent down sections of metal such that the “tires” are touching the ground. You will want to pay attention to the charge markings on the motors, as the tires will need to go in opposite directions. Make sure that one motor is placed “upside down,” as compared to the other.

•Form the back wheel. You will need a back wheel so that the robot doesn’t drag. We Took a large paperclip and form it into the outline of a TARDIS or a house, with a medium-sized round bead at the peak. We Placed it at the opposite end from the protruding wires and hot glue the ends of the clip to the sides of the battery holder.

CONTINUED• Now we soldered the wire of robot with the help of soldering machine and soldering iron

to connect• First, we solder the connection of the two switches.• Next, we solder a small wire between the two center connections on the switches.• We Soldered two wires, one from the negative motor and one from the positive motor,

to the final connection on the switch.• We Soldered a longer wire between the remaining connections on the motors

(connecting the motors to each other).• We Soldered a longer wire between one of the back connections between the motor and

the back section of the battery holder where the positive and negative charges meet.• We Took the positive wire from the battery holder and solder it to the center, touching

connections on the switches.• The negative wire from the battery holder will go to the center connection on one of the

switches.

CONTINUED•

Create the feelers for the robot. Cut the rubber/plastic ends off of the spade connectors, open up two paper clips (until they form a shape like a bug’s feelers), and attach the spade connectors to the feelers with more heat-shrink tubing.

• We attached the feelers to the switches and the servo motor. We  attached the feelers to the switches using the spade connectors and glue (if you need it, they should clip or slip on just fine) then connected the servo motor directly to the center back of the battery holder.

•Now for giving shape to our beetlebot robot we used a bottle of cap which we connected to our solar panel by connecting insulator wire.

NOW LETS GO TO TEST IN THE SUN
