Step 13: Wiring

In order to make the wiring for the RoboBrrd as tidy as possible, ensure that all of your wires have some extra length. This will allow us to be able to wire in all of the connections outside of the base which will make it much easier.

The wiring for the RGB LEDs has 100 ohm resistors on each colour lead. We use heat shrink to ensure that none of the leads will be touching eachother.

The RGB LEDs will be mounted on the front face below the top coffee stir stick. There should be a little ridge on the LED that will assist with making it stick to the edge of the coffee stir stick. We will want to make sure that these are as perpendicular and straight as possible, as we will be adding the googely eyes to it.

The wiring for the LDRs is similar to the RGB LEDs. There is also a splice near the end of the wire that breaks out the signal wire from the ground. The ground has a 1k ohm pull down resistor on it, which is also heat shrinked to another short piece of wire to extend the reach of the ground.

The LDRs will be mounted on the top corners of the RoboBrrd structure. Gluing them should be trivial as there is enough room, and the heat shrink provides a good service to press into the glue.

The wires from the LEDs and LDRs can be twisted together to save space. They should be routed into the ledges on the side faces in order to not interfere with the beak mechanism or wings. From here, the wires can drop down into the hole and into the base.

For attaching the wires to the proto-screw shield, I typically try to allow the wires that may most often need to come out near the top ‘layer’. In this case, it would be the servos and DC motor. Since they will be going over all of the other wires, we will leave them to last.

To make the wiring look neater, try to make the wires go all in one direction. This will also make it easier to place the shield back into the base. You may have to tilt the shield to have it go back into the base.

Once the shield is back in the base, attach the servo connections, as they may protrude higher than the base. Next, attach the Arduino through the side of the base.

Give everything a test run to make sure that nothing was nicked while moving the shield back into the base. It will also be good to ensure that no wires may tangle the rotational servo.
We really appreciate your efforts on this project . I assure you that we will give it our best to become one of your first prototyes. When our Robotbrrd is complete we will post up what we have. As an instructor and teacher at Eaglesnest Robotics Learning Academy, I am proud that this activity will be entered into our curriculum and used to teach many of our students how to program and construct a robot. Thank you for your efforts. Our Vote is in.<br><br><br>Sean Lewis<br>Eaglesnest Robotics<br>www.eaglesnestrobotics.com<br>&quot;Exploring Young minds through Science and Technology.&quot;
Thanks so much Sean! It's always a pleasure seeing NEON NOODLE's robots on the Robot Party. :)
<p>BRAVOOOO... Very Well...</p>
<p>Impressive :-)</p>
Our best end goal should be competent to produce RoboBrrds along with band together through educational facilities to make RoboBrrds towards scholars because Build it yourself solutions them to put together, and utilize as the program. It is extremely helpful, as the scholars have a exceptional hitting the ground with their very own RoboBrrd considering that /they/ build it and therefore are capable of make it better. These are understading about several subject areas aided by the their production. It is just a marvelous expertise <a href="http://rate-my-professors.com/" rel="nofollow">http://www.rate-my-professors.com/</a> .
Hi ! I really love your project. I'm trying to make a Robobrrd but it's not easy to find the different parts in France. Could you give me more details about them ( references for the electronics and circuits). Thanks a lot!! And once again : BRAVO !
Whoa. My kids would love making this. Thanks!
Awesome project. I am a teacher at an elementary school and this has given me some great ideas for lesson plans.
There's a problem with two of the images for the bottom face. The thumbnails are present, but when you click on them, they are &quot;not found&quot;. The missing images contain the dimensions for the bottom face.
Heya!<br><br>Just uploaded all of the design files to GitHub. There are pdf versions available too, so you can download the entire repository as a zip and get all of the dimensions. :D<br><br>https://github.com/RobotGrrl/RoboBrrd-Design-Files<br><br>Hope that helps!
Yes, this is a known issue. Since this was an entrant into the laser cutter contest, the rules don't allow us to edit the Instructable. :/ We'll update it as soon as we can!<br><br>The weird part is that the image itself was uploaded fine, and worked fine for a few hours afterwards. Something strange must have happened on their server.<br><br>There will be more CAD images uploaded soon as well, I'll reply back with more details :)<br><br>Thanks for the comment!
Beautifully done. Inspiring young mind will benefit much. You're motivating them into a better future. ○☺○
Thanks so much Evelyn and alfiefalf!
I'm Doing my best to draw some good attention to the instructables site, I think maybe giving my family and friends the link to your page for RoboBrrd might help just a bit...<br><br>N2TOH<br><br>Pst, ... Laser cutters are cool, pass it on....
Thanks N2! Every bit helped, I'm sure. :)
What a wonderful project- thank you so much for sharing! I've been working on a robot project with my three boys and this has given me some great ideas. :)
Thanks Honus! Congrats on being a finalist in the laser cutter contest.
Your instructable is very detailed, but I think this step is not easy for beginners to follow. The schematic with the 2 protection diodes is on page 10 in the datasheet, not page 9 and it is difficult for beginners to see how the parts are connected, if they are not used to read datasheets, e.g. the right polarity of electrolytic capacitors and the connection of the LM317. It is not the circuit you are using, but I think this a good example how it could look like: http://laserpointerforums.com/attachments/f42/31562d1298103794-diy-homemade-laser-diode-driver-31410d1297294173-logical-way-setup-2x-lm317-driver-lm317.jpg
Off by one error on the page number, apologies!<br><br>There were additional pictures of a breadboard as well that help with the wiring.<br><br>I'll revisit this step and post some step-by-step soldering pictures for this on some perfboard, this should help! Plus, perhaps a drawing of it in Fritzing or the like.<br><br>Thanks for your feedback!
RoboBrrd &lt;3
So cute and it hula hoops!<br><br>This is a very thorough instructables and a very interesting project to introduce younger children to robotics and programming. I love the concept and the idea that you used simple everyday materials for the construction was ingenious!<br><br>I hope you get the funding you need to create your kits, I know I will certainly buy two. One for me and one for my sister who is applying for teaching jobs in elementary and high school for technology! She loves these types of things to show the students. She tutors a young girl now and showed her how to make a vibrobot using a toothbrush. <br><br>Good Luck! Wonderful instructable!
Put us down for at least 5 to start with.
Thanks sailormoon (your username brings back memories hahaha)!<br><br>Hopefully that young student will keep interested in robotics and make cool robots too. :)<br>
Such great creativity and accessibility, awesome!<br />
Thanks a bunch mikeasaurus! I love your halloween cheese burgers! Hahaha so cool. :)
This is incredibly thorough documentation.
Thanks James! Lookin' forward to seeing your 3d printer on the Robot Party this week! :)
