Step 15: Felting

Now we need to make the RoboBrrd not look like a skeleton anymore! We will be adding felt to the outside edges of RoboBrrd. The most difficult areas to felt are the front face and the beak.

For the front face, you will want to begin with a piece of felt that is a couple of cm larger than the size of the front face (10cm). From there, we will poke some holes for where the LEDs will appear through. When doing so, you will want to make sure that the top edge (with some excess felt on it) will be remaining straight, parallel with the top edge of the front face.

Now, we have to measure and estimate where we should be cutting for the beak opening. The best way to do this is by holding the felt on the front face, and marking it from the inside of the RoboBrrd. We will want to mark where the beak edges are, creating a diamond shape.

Begin by cutting a small ‘plus’ in the middle of the diamond. Place the felt on RoboBrrd’s face and see how much more longer the plus sides have to be. The beak should be poking through the plus a little bit. Keep on repeating this process until the entire beak can pop through, and the felt is flush with the front face. Now you can glue the felt onto the front face on all edges.

For the beak, we will need to divide the process into felting the ‘top’ sides of the beak (the one with the nose bridge), and the ‘inside’ of the beak (where teeth would be if birds had teeth).

Take a piece of felt and measure to see how long it would need to be to wrap around the entire top side of the beak. Cut it to the length, and add a little bit of glue in the middle near the side of the longest edge. Stick this onto the bridge of the nose as close as you can get it to where it meets the front face. If it sticks to anything other than the beak, be sure to cut it.

By pressing the felt across the nose bridge and onto the sides of the beak, you can create a nice smooth shape. You will want to ensure that some of the felt is attaching to the edges of the beak, which may be hiding behind the front face, on the inside of the RoboBrrd.

When everything is smooth, add glue to the edges of the beak and press the felt onto it. When it dries, cut away the excess felt, leaving an extra 3mm. We will wrap this extra felt onto the inside of the beak. Add some glue to the inside of the beak nearest to the edges and press the extra felt into it. The tip of the beak may need some additional gluing.

Repeat this same process for the other beak half.

Now we will be adding the felt for the inside of the beak. We will want the beak to be open at its widest point for this. Take a piece of felt and measure how wide it should be and how long. For the length, add an extra centimetre. Start by gluing the top-center of the piece of felt to the tip of the top beak half.

From there, you will want to move the felt down, towards the tip of the bottom beak. There should be some extra slack in the middle creating a bump. The bump should be about a little less than a centimetre  tall. Glue the bottom-center of the piece to the tip of the bottom beak half.

Now, press the bump of excess felt through the opening between the two beak halves. This is used for creating a seamless feel between the two beak halves. Ensure the felt is laying flush with the insides of the beak. When it is, add glue to the inside edges of the beak and press the felt into it. Cut off all the excess felt, and it is done!

For the side faces, create a 10cm by 10cm square (with a bit extra if you want to be able to trim it to length), and add an opening for the wing servos. Be sure to only glue this along the top edge, and along the side edge to where the opening is. We do not want glue on the bottom or opposite side edge as we will need to lift the flap to be able to see the insides of the RoboBrrd.

The back and top face is a similar approach. Only the top edge will be glued on, so we can lift it to reveal the inner workings of the RoboBrrd.

For the wings, we will do the same process as we did with felting the top of the beaks. Cut the felt to the proper length, then add glue to the top of the diagonal piece. Then smooth out the felt for the other edges, add glue, and press the felt into it. Cut away the excess felt, leaving an extra 3mm to be used to wrap around the the bottom of the wing. Add glue and press the extra felt into it, and the wings are done!

When everything is felted, we can move on to the next step.
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! :)
