This week, we presented at the CBL forum. A bunch of parents, students, and faculty members came to learn about our projects. We put our poster, our collar, our iPad with our website open, and some candy for people to take on our table. Our poster included our solution, our problem, our data, and a few photos. To get a better sense of how our collar worked we used our collar as our interactive object, so people could cover the sensors, and feel what the vibration is like. We have taken away many things from this experience, like how to answer questions on the spot, how to be good at public speaking, and more. We have also learned a few statistics about blind dogs! We were very happy to hear that many people thought our idea was a great idea, and even a few people recommend that we continue making these collars. We made an order in which we spoke to our visitors in, Peyton talked about the problem, Lilah described our solution, and Phoebe explained our data. We all switched off taking videos from behind our booth, to capture as much footage as possible. Overall, the forum was a really fun experience and we learned a lot!

This week we have collected data from our collar based off of humans and dogs, and we have added another part to our collar. The newest part to our collar is a 3D printed box that holds our hummingbird code. Our first print of the box did not work well because the box was too small, and the holes on the side were too small to fit the wires. Then we printed another box that sort of worked out, but one of the holes was too small, so the cord did not fit in the box. Then we found a solution to fix this problem. Lilah used her artistic skills and figured out a way to make one of the holes bigger. She took the tip of the hot glue gun and melted the plastic to fit the cord through the hole. If we did not have her help, then we would have gotten nothing done. After we finished that problem, we started to take data from our collar. We tested our collar on Phoebe outside and we tested it on Lilah inside. When we tested it on Phoebe it did not work that well because we mixed the wires. When it vibrated on the left, it was supposed to vibrate on the right. When Phoebe did not have the collar, she bumped into five things, and when she did have the collar, she bumped into one thing. Then we fixed the wires so it would be right when we tested it on Lilah inside. When Lilah was not wearing the collar she bumped into ten things, and when she was wearing the collar, she bumped into four things. Our data from our collar taught us that it can work really well for dogs that are blind. This is because when we tried it on humans that were blindfolded, it helped them get around easily. The number of times they bumped into things went down because the collar navigated them where to go. The data proved to us that this collar will work really well, and will benefit blind dogs. If we had more time then we would have built the code in the collar instead of it outside in a box. We also would have wanted to make look better because it is very messy with all of the wires sticking out. Another thing we would have wanted to change, is how comfortable our collar is.

This week, we are mainly trying hard to take the prototype we currently have, and make it better.We are making all possible improvements, before our data is due, next Friday. Right now, Lilah is working on photos and videos and Canva, Phoebe is doing Canva and coding, and Peyton has been working on the 3D print. Kevin is not in science this week, so we have subs. The first day of class, we had someone come in and teach us about how to make good poster boards. We learned how to use contrast, varieties of fonts, proximity, organization and more. We are now taking all these skills and putting them in our poster. Aside from working in our Canva poster, this weekend is our big testing day! We are all meeting up on Sunday to see if our product works. We will take data, then fix the problems with the prototype, so that our final product works well. But, we do have a few problems. First, we were not able to pick up our 3D printed case for the mechanics because by the time it was finished, the create studio was closed. Another problem, is that we were not able to find a blind dog. We are thinking of using Phoebe’s dog, and just blindfolding him. And as far as it goes for the case, we are probably just gonna have to use a regular cardboard box that we find in Phoebe’s home. It is currently Sunday and we are ready to test out what we have so far! We just began and realized that we do not have access to the code. We do not know how to get the collar to work. We emailed Kevin, but after trying everything we realized that we need the school computer. So we were not able to get much done today. Our specific solution is a collar with sensors so that if the dog were to get near something on its left side that is about 15 inches away from them the left sensor will vibrate. The same thing goes for the right side, and the front. Even though we are currently having some issues with our coding, we are hoping that we can stick to our solution.

This week we have starting working on coding. We did have some difficulty in the process, but we are not going to give up. We have done a lot of work with figuring out how to assemble the vibration sensors that are going to go in the dogs collar. While learning to code, the wires were giving us some difficulty. The wrong ones were going off at the wrong times, but we are definitely going to keep trying until they are all right. We have made a few adjustments since our last blog. We were going to have four sensors, one in the front, one in the back, and one on either side. We are now only going to have two sensors, one on either side of the collar. This way, if the dog gets near something on the left side, the left sensor will vibrate, if the dog gets near something on the right side, the right sensor will vibrate, and if something is in front of the dog, both sensors will vibrate. There are a few different reasons we have decided to make this change. One is that it is just too much. The machinery that we are putting inside of the collar would probably not fit 4 vibration sensors, and the collar would be way too huge if we were to add more machinery to make it fit. Another reason is because we want to make sure the the prices are reasonable. If were to actually sell these, it would be too much to be adding four sensors in the collars. We would want to make sure we make a profit, and adding extras sensors just doesn’t seem necessary. Another thing we have changed since last time, is the water proof aspect. After getting advice from a Windward employee, our group had decided that it would be a great idea to make our collars waterproof. We have now looked more into that, and now realize that it is not that simple. In order for the sensors to be able to decent how close/far away the dog is from things, the sensors are going to have to stick out to the outside of the collar. There is no way that we are able to protect the sensors from getting wet, for example if there is rain, or the collar were to get dunked in water while the dog is hydrating. We have talked to our teacher to see if there is any way, but so far, because the sensors have to be out in the open, and not inside the collar, we have thought of nothing. The last update is that we have now planned a day to test out our collar! We have decided to stick with the original maze plan, and build it out of pillows. We are going to bring a blind dog to one of our homes and test our collar on that dog in the maze we create. We are crossing our fingers and hoping for the best outcome!

This week our group has worked on getting feedback on our solution and revising it. We had one class fully devoted to getting feedback from some of the Windward faculty members, and we received many great ideas. One of the faculty members brought to our attention that the collars should be waterproof, because blind dogs are probably going to be in situations were they could get wet, for example, they could go on a walk while it’s raining, they could be drinking water and accidentally dunk their collar in the bowl, and many more situations.One of the other main topics brought up was the number of sensors on each collar. At first we were just going to put two sensors on the collar one on the right and one on the left, but someone suggested to us that we make a few more sensors to put on the collar so the dogs have extra protection. After receiving the feedback our group thought hard, and came up with some ideas to improve our solution. The main goal of our solution is to help blind dogs and to prevent them from getting injured, so we have decided to put four sensors on the collar instead of two to keep them extra protected. We are going to keep the idea of having sensors on the right and left side, but we are going to add one in the front of the collar, where the dogs name tag goes, and we are adding one on the top of the collar to notify the dog if there is anything above them. We also think it is necessary that we make the collars waterproof, so blind dogs can wear it basically wherever they go, in any weather. We have not yet came up with a way to make the collar waterproof but we are thinking of ideas. Although we have only made slight changes to our solution, we think it will give blind dogs a chance to feel and act like they don’t have a disability. We also think that after getting the feedback and making our solution better, it can really improve not only blind dogs life’s, but also their owners life’s as they won’t have to worry about their dogs. A few people giving us feedback had mentioned that it will probably be hard getting feedback and data on our solution from the community using it, because dogs can’t really communicate to us. In order to get data we have came up with the idea to create a short maze for a blind dog to go through, once with the collar on, and once without the collar on. All three of us will count how many times the dog bumps into the walls to make sure our numbers are accurate. After, we will compare the numbers of times the blind dog without the collar on has bumped into the walls, and how many times the dog bumps into the walls with the collar on.This will give us an idea of how much the collar helps blind dogs get around without bumping into things.

This week our group has continued working on a solution that will help blind dogs. We decided that we were going to make a collar that will help the dogs to get around easily. In the collar there will be sensors that will detect if the dog would bump into anything. The sensors will make a vibration so the dog would know to move in a different direction. We knew that we wanted to create something that would help blind dogs, and this is what we came up with. Another solution that we were thinking of was making something that you would spray on furniture, and then the smell would repel the dog from running into the furniture. We know that there is some type of variation of the collar idea that we came up with. The animal would wear its collar and the device that would help them “see again” would be hanging from the collar. This idea was sort of similar to ours, but we are going to design the collar so that the sensors will be built in the collar so it would better for the dog to wear. The solutions that the other people have made seem to work really well. On their website they said that it was really effective and it helped their disabled animal.

Welcome to our blog page! We are excited to show you all about what we are working on for our CBL project, a huge project that is used to help out something or someone in need. This year's big topic is movement. The broad topic that we currently have settled on is blind dogs. We started off with the even broader topic of disabilities, which then became animals with disabilities, dogs with disabilities, and now, blind dogs and how they get around. We decided to work on this topic because we feel that animals should be equal to humans. If humans get many complex helpful systems for their blindness, then dogs should as well. As a group, we own three dogs, none of which have blindness. We were all interested in what it would be like to have a dog who can't see, and how hard it must be for them to do simple things like getting around place to place. Right now, we have the idea of a collar that vibrates when you get near something. For example, if the dog was walking and there was a pole on his or her left side, the left side of the collar would start to vibrate, until the dog backs away. As a group, we have decided to focus on that small detail, of blind dog transportation. Our goal is to come up with a great invention that hopefully helps blind dogs in need.
