This is my first instructable and I am not native English speaker, so please let me know if there is something not clear enough. I am using the metric unit system.

Well, what is the Insect Bot. Actually it's not really an insect because it only has four legs, insects does have six of them, right? However, the robot got the name because of his shape with the thin wire legs and the IR sensor rosed up.

That robot already has a long history. first I built one with standard servos and an Arduino UNO but soon I wanted it smaller and even more easy to build. After a couple of attempts with different designs this one is the final one.

Here you can see the big one: letsmakerobots.com/node/26194

The following is the step by step description, how to assemble the robot and if you are already a bit skilled in such things then it will not take you more than one hour of your time.

This first video shows how the robot could walk after switching it on for the first time and without adjusting the legs :-)

Step 1: Servos Building the Body

Stick both servos together by using double sided foam tape. Front servo shaft in top and rear servo shaft on the backside.
Make sure you align them properly that they build a nice body for the robot.
<p>Hai,</p><p>Can Insect Bot mini works with a ATtiny85 please</p><p>Is there someone who has done this</p><p>Kind regards</p>
<p>Great fun, first Arduino project. Legs need tuning though.</p>
<p>I've been interested in electronics all my life but never got into it until about three months ago when interest got the best of me and, at 76 years old, I started playing with Arduino UNO. I've done the sketches, read a lot of instructional books and continue to do so. I have not done anything of my own. I will do this bug! It seems to me to be lots of fun. Most of all, your instructions and accompanying photos make it irresistible for me to tackle. I will definitely send you pics when I complete it. Thanks for posting your instructable. </p>
<p>Got it, built it, loved it. My son's new best friend. Not so much my cat's.</p>
<p>Great, I hope you can provide a video as well, so I can add it to my collection :-)</p>
<p>IMPORTANT! The sensor cable supplied in the kit I received today from DFRobot was wired incorrectly. It was a &quot;servo-type&quot; cable JST to .1&quot; header with red, black, and yellow wires. The red wire went from the center JST pin to 5V and the black wire went from the left JST pin as seen from the front of the sensor. This arrangement connects power BACKWARDS to the Sharp sensor. To make this cable not fry your sensor, you need to reverse the red and black wires at the JST connector. (The yellow wire is OK.) Use a pin or needle to lift up the plastic tab on the JST connector just far enough to slip the crimp-ons out. Then reinsert them so that the wires are red-black-yellow, left-to-right, as seen from the front of the sensor. I assume this is only necessary if DFRobot sends you this cable instead of the red-black-blue one shown in the Mini Insect Bot Wiki.</p><p><br>The DFRobot kit also came with some kind of USB dongle which I presume is a device for charging the battery, and an extra male PCB mount JST connector. At first, I thought the extra connector was intended to replace the .1&quot; power headers on the shield, since the battery connecttor is a 2mm JST and is not an exact fit for the headers. However, the JST connector can be made to fit on the power headers on the shield with some judcious bending and a little more force since the header pins are thicker than 2mm JST pins. Be careful with battery polarity - a LiPo battery may actually catch fire or even explode if connected to a charger backwards. <br><br>Bending the legs is the trickiest part. The wires are sharp on the ends - wear gloves or be careful. The wires don't have to be a tight fit in the servo horns to work. It's useful to wait to screw down the servo horns until after you start the device up for the first time, so you can center the legs. Centering the servos precisely doesn't seem necessary.<br><br>A fun kit - unlike my other robots, which have fairly noisy gear motors, it's quiet enough that the Cat is fascinated by it rather than frightened.</p>
<p>Thanks for the detailed comment.</p><p>Yes, it happens that the cable for the IR sensor is wrong so I wrote a short note in the Wiki <a href="http://www.dfrobot.com/wiki/index.php/Insect_bot_mini." rel="nofollow">http://www.dfrobot.com/wiki/index.php/Insect_bot_m...</a> However, I will add this to this instructable too. </p><p>The additional PCB mount JST connector for connecting the battery is optional. Since the Beetle shield is not only for the insect bot the power pins are not deticatd for that kind of Lipo battery only. </p><p>The wire for the legs is indeed a tricky part. Since the legs needs to be stiff enough to keep the shape and soft enough to bend the 304 stailess steel wire seems the best option even if it's still hard to bend when doing the small 90&deg; bend.</p>
<p>Had a great time building my first Insect Bot, that is also actually my <br>first robot ever. Still impressed by how simple it is to make all in all <br> (though facing some challenges along the way that keep the excitement <br>high), with such a cool design. Looking forward to the v2 ! </p>
<p>Nice job. The kit is well packaged and we were happy to receive it so fast.</p><p>Unfortunately the + and - pins are missing on my shield (see pictures). Kid's disappointed :( </p><p>I won't return it because shipping is far too expensive from here.</p><p>Also there's no info about charging the LiPO. How do we know when battery is charging or fully charged, or broken?</p><p>It's missing a link to this instructable too :)</p>
<p>Yes, unfortunately there is a wrong batch Beetle shields without the pins soldered on. If you do not have pins available at home thern you can use a piece of wire to connect the both pads from the shield with the Beetle. </p><p>The next batch of Beetle shields will have the problem fixed. Thanks for pointing out the charging pattern.</p>
<p>I found by myself about the LiPO: LED on = charging and LED off = charged.</p>
Hi Lumi! <br> <br>Great instructable full of useful details, tips and good pictures! I'm looking forward to see you next instructable. Keep going! <br> <br>Kind regards, <br>Francisco
LOVE IT _ Looks awesome! I made an arduino bot once...this is way cuter!
Thanks Holly, yes it's awesome but even more awesome is to see the kids having fun building it :-)
