Simple Solar Robot




About: problem? didn't think so.

in this instructable i am going to show you how to build a simple solar powered robot.

(the pictures below are in order from the list)

like any project you will need some parts and tools.

1x solarbotics scc2224
1x 1.5-3 volt pager motor
3x paper clips
google eyes
wire (to make antennae)

wire cutters
ca or super glue
soldering iron
hot glue gun
clamp (optional)

Step 1: The Body

first begin by gluing the motor to the underside of the solar cell with ca glue. note how the power leads are facing the solar cell's connection pads. clamp if necessary until the glue dries. again the pictures are in order so if you get stuck look at the pretty pictures.

Step 2: Soldering

trim the motor wires if necessary (mine were trimmed before hand).  solder the black wire to the pad marked - and the red wire to the pad marked + . it should look somewhat like the one in the picture.

Step 3: Test

test the body by sticking it under a bright lamp or in some bright sunlight. you should feel some vibrations.

Step 4: Leg Preparation

set the body aside for a second and bring out the paper clips. start by unfolding them as in the second picture. then with the wire cutters cut the smaller end off. after that take the big end and cut off any extra until you have a u shape as in picture three. then cut off the semi circle part of the u, until you have two equal metal "legs". repeat three times

Step 5: Finish the Bot

apply a bead of hot glue along one side of the motor can,as in pic. two warning do not get the glue on the spinning part of the pager motor or the bot will not work. then quickly stick three legs into the glue as in pic.three. level them out then repeat on the other side. i recommend that you add more glue to the motor can to seal the legs in as pic.four. then you are done.

Step 6: Extra Stuff

you can leave it as it is and play with it, or you can make it look like a bug as i did. all i did was i glued some big google eyes to the side of the solar cell, and shaped some wire to make antennae.

    Very well thought and practical, thank you corn holio for sharing. I will try this with two toothbrush heads on either side of the motor instead of pins. Nanobots invading !

    Ok so I bought that solar panel and the motor and it didn't work. I also checked the motor and it worked. Got any suggestions?

    If the solar panel is like the one in the picture, it is a good chance that it may be faulty. These are cheap panels, mostly made without appropriate Quality Control. Better check the voltage from panel under sunlight with a voltmeter first. If you do not have a voltmeter, you may check it with first with a green led (most of them 3v), then a red led(1,5 v). Green check is for avoiding burning the red led if voltage level is high. Generally you would see nothing with green led but a glow in red. Be sure that you test with the correct led pin + to + and - to - since leds are diodes working only one way.

    your motor may draw too much current. i would recommend that you add a solar engine to the robot (miller configuration, google it) this project was designed to "pave the way" for people who want to get started in B.E.A.M. robotics. thats why it does not have a solar engine built into it. i have been building beam bots for years and i have acquired a lot of knowladge on the subject. i will release some more instructables on how to make all sorts of solar engine, and i may post some videos. please do not get frustrated as it takes away the fun of building these things (belive me it turns a simple weekend project into a living hell) so all and all dont get frustrated and i am always ready to help

    Thanks but can you put the exact url that you bought the solar panel because I don't want to buy the wrong solar panel.
