Neat idea to remove the gear boxes from the motors to achieve higher speeds. Did you consider just gearing the motors using external gears instead of removing the internal gear box (just wondering if that would be easier for others to replicate). Have you thought about use cases for this design? Maybe as a reaction trainer for athletes or entertainment for a pet?

Cool! I liked the model use in the video, and the bot was surprisingly accurate in its shot. I’m curious how you could apply this to a real-world use. The re-design of the motors is impressive and the whole build is creative!

Of course, all shots that may stray towards living targets are all considered accidents, right?

Were there any animals harmed in the making of this project.

Nice! How fast can the robot adjust – does the ball need to be rolled really slowly or can it defend against hard hit shots?

This is really cool! I love how you created a field for this project and it seems like your robot reacts really fast.

This is so cool! Have you experimented with different kinds of paints and markers? It’d be super awesome to combine this with a camera so it takes a photo of someone, emoji-fies it and then draws it out. Is the image hard coded or generated programmatically?

I love how you had the robot send an email of the picture it drew!

This is such a cool concept! I also thought your video was great because I liked seeing both where the idea came from and the final robot in action!

This is so cool! I love that instead of using a pen or pencil you use paint. What other paintings do you think you can make it paint?

Cool idea – are there any tools available on the web like this? I wonder if you could add some multiple choice questions to supplement the image data and use multiple factors to decide if more medical intervention is needed.

I was so drawn to this robot! It was the first one I looked at in the gallery. I love how you combined driving and robotic arm action. There are so many possibilities moving forward. Great work.

I really love the idea of using a color sensor for identifying the notes. You should consider adding more colors and “programming” a whole song.

The motion of the robotic arm is so precise! This is so cool

The use of colors to depict notes/time duration is a really smart way to get a robot to play a song. The motor movements were also really precise too.

I really like how you added the voice cue for the dog when you throw the ball!

I like that a dog can play with the robot by itself! My dog would love this

I like how you programmed it to respond to your dog’s barks. It makes it a bit more personal to the doggo:)

The attachment of the speaker on the top is really clever so that you can still drive your robot around. Have you mapped the amount of power required to hit the ball to different lengths?

I love this idea! I have this struggle as well with my family. It’s always when you just settled down too:((

I really like you found this daily life problem to solve! Great work 🙂

Another idea would be to have one that works remotely especially if it had a camera – so I could check if I forgot to close the door to keep the dog inside and if I did, I could trigger the robot to close it!

I definitely need this!

Hi Aron! After seeing many iterations of your door closing arm, I’m glad to see the final prototype work so well. Iteration is one of the most important aspects of programming and to see this version work so well goes to show just how much effort you put into this robot. I appreciated the use of the green line follow as well, as your robot worked smoothly to close the door behind anyone. I hope it comes into good use as a door closer especially if you’re ever stuck on a Zoom meeting! – Phoebe

Very cool – do you think you could add different fonts? Or a rotating set of markers so that every letter could be a different color? I like how you used the rubber bands to raise the marker.

That’s a great project – there is lots of room for expanding it. Making it recognize different types of characters from other languages, or using Machine Learning to learn how to mimic handwriting. I loved the idea!

Wow! I love how “roboty” the font look. So impressive you got all the letters!

love this! could you program more words or series of phrases?

Cool! Its really impressive you were able to write so accurately! In the future, you could program it to write a word you type in a box. It would take a lot of time, but that would be a really interesting and helpful real-world use!

This is very impressive! What is the robot coded to do and how long did it take to code?

I like the idea! What other information would you want to show? It would be cool if your robot can identify demographics of people and show optimized information to them!

What ideas do you have to make it recognize faces with darker skin tones?

I think that this robot could be highly marketable to the government and its applications are endless

What libraries did you use to make this happen? I’m interested to hear more about the magic mirror software and other ways your robot could talk to it. Could your robot measure light values and turn the mirror on when it gets dark?

Hi Riley! I was happy to see the program work so well. It’s in line with a lot of the features now seen on iPhones and computers, using facial recognition to unlock devices and whatnot. Adopting new libraries into your code was challenging especially on Jupyter software and I’m glad I got to see it work, despite hours and hours of debugging. I hope you include more softwares to customize your computer in the future and push to see what facial recognition can accomplish! – Phoebe

First thing I did when I got on this page was take a drink of water 🙂 Great project!

This is great. My coworker has a bottle that lights up to remind her but that’s too easy to ignore! This robot would do the trick.

I love this! I especially like how you used both sound and lights. It would definitely help me to drink more water at work!

This is such a creative project! I would use this daily. Are you able to adjust the frequency of reminders to half an hour instead of an hour?

I love the idea! Very creative. You could also keep track of how many “sips” the user takes in a graph, so you have an idea of your progress so far!

Hi Sami! I’m happy to see you implement a solution for a common problem. I honestly want to use this myself because we’ve talked about my lack of water intake. I think this program is versatile too depending on the settings of the user and could benefit from an input request so that it changes how often the user is asked to drink water. I loved the addition of the speaker too so that it would communicate via light and verbally to the user! Hopefully it comes in use this summer! – Phoebe

Could you add a feature that sorts by suit also?

This is really cool! I wonder if you could make it also pick up the cards from a deck so that a person doesn’t have to do it each time

This is really cool! I wonder if you could make it also pick up the cards from a deck so that a person doesn’t have to put one down each time

I love how many actions this rover can perform! When you collect the blue ball, which sensors are used?

I like how you managed to use almost all the modules in the kit (motors and the sensors). I imagine that this is using the finite states “design”, changing from a “driving state” to a “grabbing state”, right? You could also include a “mapping” function that stores where the obstacles are.

That grabber seems so fast and efficient in the video! Nice design

This robot does a great job utilizing all of the motors and sensors we had. The use of the servo to collect the colored balls is incredibly clever.

Were you inspired by rovers looking for water on Mars when deciding to make the rover search for blue things, or was that just a coincidence? Either way, this is really cool!

I love this little rover! I find the mars rovers fascinating and I love how you drew inspiration from it to create your project. Did you implement any way for it to talk to mission control when it finds something or sees an obstacle?

The mechanism for the scooper is something I hadn’t though of, I love the design

Pretty neat! I like you leveraged visualization so human can see how robot thinks. Keep up the good work!

I know that the project didn’t turn out perfectly, but I love the idea and it shows that you worked really hard on it!

This is great! It seems like you got pretty close, and definitely worked hard on the concept. I think with a bit more time you could definitely have it working!

Nice! Can you think of any applications for this robot? Maybe it could be turned into a game or a way to entertain a pet?

This is a great use of proportional control.

I like how you included the code in your video! Seeing the code really helped to illustrate how the robot worked. (:

I like how you thought of being able to control the direction in a simple way. What type of hand motions would you program for turning the robot?

I’ve always thought this concept was incredibly cool, and you executed it wonderfully

Nice work! You could try including a proportional control to make the motion smoother, but calibrating its values (target and error) might take some time.

super cool!! did you use proportional control or a serious of conditionals

What other sensors could you add to give your car additional decision making factors/the ability to add more functionality?

could you make this robot turn both left and right with this one sensor?

I like the name, it looks like a smooth motion too, which is great. Good work! Are you using proportional control?

Great name! It moves so precisely.

I love your confidence in the robot.

I like how it gives some allowances for turning, as it is hard to turn on the spot while smoothly following the line. Good job!

This is awesome – perfect for practicing without a human partner. Could you add some additional sensors to track stats/hits etc. and use that to give the user feedback on their training?

I love the acronym! I think this is a very creative project, especially utilizing a 3D printer. How did you two work together remotely? Or were you in person?

What was the hardest part when making this robot?

It’s so reactive! It moves really smoothly, which is so cool since it’s such a large robot!

This is a great project! (Excuse my lack of fencing vocabulary but) when you hit the cardboard person, can the robot help it stand up again?

wow! was the most difficult part of this the coding or the building?

This is impressive! I didn’t think the motors were powerful enough to move the entire structure. Really nice how you added 3D printing to it.

As a trail runner I really like this idea – but I’m wondering if it would be more useful as a safety system rather than to function as a stopwatch/timer? I love the idea of a robot that sits at the trailhead and waits for me to come back, and if I fall or am taking too long it sends out an alert or calls an emergency contact. Cool idea about the robotic encouragement though, I like that a lot!

Interesting! It seems really useful for runners. It could also be great for track meets to easily measure runners times and who crosses first without human error.

This is a really smart way to time yourself on a run without having to manually do it. I wonder what the range for the distance sensor to trigger the split is?

Your project has so many cool elements that work together so well!

I love how versatile this little bot is! It can be used for way more than running! Like biking, kayaking, skiing, anything that needs to be timed! Well done!!

SO cool, was most of your time spent coding or learning the software around these libraries.

I love how you used the Cloud Vision API to detect the text! Involving resources outside of just Python was very creative!

I really like this project! I struggle with languages a lot and this would be very helpful to have. Very creative, using the Google API

Great idea, you executed it perfectly!

Very cool. This reminds me of the google translate camera mode that I used in French class.

I really like both your project and your explanation of it! In your video, you broke down the complicated concepts into simple ideas so well.

The translation of signs that don’t match what you know as “normal” sounds super helpful!

You have impeccable manners.

This is a great project! I can think of a lot of great applications for this. Might you add a feature that speaks out the translated text as well as prints it?

This turned out great! I wonder if in the future you would consider giving the user the possibility to choose the location and then the drone moves there autonomously.

This could be used as a dog walker!

I think that this could have many applications and I really like your inclusion of multiple modes!

Your project is beautiful! I love how you thought outside of the box with this project.

This is amazing! I like your crafts and how you made them interactive. I’d like to make my own aquarium bot using your instructions if you have 😀

This is amazing!! I have two clownfish myself however I don’t believe they have a camera or a distance sensor attached. Well done!

This looks so good Avery, and the fish are so cute!

This is beautiful. It’s nice to see you spending so much attention to detail and appearance.

This looks fantastic! I hope you can enjoy this long after the course is over!

I love how you were able to incorporate many different sensors and actuators- well done!!

Hi Avery! This project really expanded the concept of what a robot can do and the inclusion of the photo with the dismantled parts proves that anything can be robotic, including a diorama of a fish tank. The blend of art and robotics is the definition of STEAM to which it comes out in so many moving parts in your display. I’d agree that addition of music would be a great addition should you choose to continue working on your aquarium and am hopeful you keep working on personal robotic projects in your future! – Phoebe
