Step 8: Rotational Servo

As mentioned in the previous step “Base Construction”, the rotational servo will be mounted directly in the middle of the base. The servo horn on the rotational servo should be the exact center (or close to it) of the base. If the controller board needs more space, the rotational servo can be moved a couple of millimetres to the left. For this RoboBrrd, we had to move the rotational servo 3mm to the left to allow for enough room for the controller board.

First we have to check the boundaries of the rotational servo. Using a 4 point servo horn, see that it can travel around pointing from the left to the right. When finished, move the servo horn directly to the middle.

We will use the circular servo horn on the rotational servo as it has the largest surface area. On top of here, we will have a small popsicle stick construction. Before mounting the construction to the servo horn, ensure the screw is in the servo horn.

Place a piece of dual lock on the popsicle stick construction. On the bottom face of RoboBrrd we will attach the other piece of dual lock. This will allow us to be able to take off the main RoboBrrd structure without having to dismantle everything.
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!

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! :)
