@Marios7+Another day another Portuguese learning day!
~~~ What I did today ~~~
Today was pretty chill till the night where I had a lot of issues with the sinerider bot. Thanks @JosiasAurel for helping me.
On the duolingo side I did some very needed revision. And I can proudly say:
@Lucas tem um cachorro!
@rajanagarwal0experimenting with fine-tuning a generative text model for a cool slack bot!
@ScottChiang-U0325L71XQR0Still not done with my WHW robot (technically). I have finished building my robot but it is not exactly the best design, so I have been thinking about upgrading from micro servos to servos. (It will result in the robot being bigger but also able to handle more of a load)
@RaymondWu-U04JJ3A7G3Z0I'm trying to make a computer vision program that detects tennis balls. There will be a ball picking robot eventually.
@Marios7+Day whatever of my life on #scrapbook!
Today I completed the sinerider bot, programmed in the Commodore 65 and played MC with @Odysseus. And also launched an Order Lookup system for Kelp LTD. I also continued my adventure on how current works!
What I didn't like about today:
+ I did ~4 hours of math for an exam. Not fun
@Odysseus0Day 5
🤒 Sick
I had some trouble breathing at school and got home earlier. Thanks asthma! I'm now fine, but I didn't go to any of my activities today, and I won't tomorrow as well, so I will work on a few things!
:netflix: Mr. Robot
Watched the final episode. This is a masterpiece, go watch it.
:duo: Swedish
Duo wasn't mad for yesterday. I did my Swedish today, and he seemed ok. I think...
📨 Letter from HQ
I got a letter from @Holly today, for a riddle! Can't wait to solve it with my Hack Club today! I just noticed that it was written on 3rd of February and it came today... Thanks Hellenic Post!
:tw_spiral_calendar_pad: Tomorrow
Boy, I have a lot to do for tomorrow! Gotta study some C, work on that Python project I haven't touched, update my website, do my Swedish, study Ancient Greek (WHYYYYY) and other school stuff. That's a lot 💀
@ManikShrivastav-U04GY2NRT5X0Day last of WHW🇳🇵
Finally my project The Gesture Control Robot 🤖 is completed and you can have a look on it. It was a great time working with this project. Hope to participate in future events as well.
By @ManikShrivastav-U04GY2NRT5X .@Marios7+Today is the 1st day of what I call, the DM ( Daily Marios ) Didn't do much because I was out of town
~~~ The 📜 Changelog of wisdom ~~~
1️⃣ I worked on the Sinerider reddit bot
2️⃣ Experimented with the Commodore 64, fascinating stuff!
~~~ :future_potato: What is tomorrow? ~~~
I want to update my winter hardware wonderland repo and create the pcb. Also experiment more with the C64.
~~~ It is :minecraft: time ~~~
Or is it? I didn't have much time today so I didn't play much :(.
@Odysseus0Day 3
Not a lot because I kinda procrastinated 🙃
🏫 School stuff
I had to study the most interesting interesting subjects today. History and Ancient Greek (pls kill me).
:netflix: Mr. Robot
Wow this show is good.
:minecraft: Minecraft
The empire is growing
:duo: Swedish
I did my Swedish just in time. I'm safe tonight.
:tw_spiral_calendar_pad: Tomorrow
So tomorrow I won't have time for coding cause I have a ton of school work to do 😞. I have school (not yay), swimming practice (meh), and math tutoring (yay!) and then homework, including a history test (not yay at all).
@BikashGupta-U04HFDWE7CH0Final video of my Human face following robot 🤖. It is working well tracking my face 😊.@Captain-A.J.0Winter Hardware Wonderland Day 8 #hardware-party
Today, I connected the Pixycam to the RoMeo BLE and ran the test code to make sure everything was working properly... and it was! When the camera sees a “learned” object, the Arduino IDE's serial monitor shows the values seen in the picture. I have also run the line tracking demo code without the camera attached to a chassis, which was also a success! So, next on the agenda: finish the line tracking code to fit my robot's purpose.
TWO DAYS TO GO EVERYONE! Let's keep pushing!
@ShouryaPandey0Started to make a platform for testing the bot and repairing it
@TheScientist1010Day 5 of #hardware-party :
Today I finally got the connectivity and data transfer between the robot and the phone for controls done. I am using Flutter for the app because of its ease of use and cross compatibility. Here’s an image of the joystick below. I need to learn how to parse the data on the robot. I will hopefully work on that today.
@XhaidenD'Souza-U04HXBNUQRM0Day 3:
I finally got the robot mechanisms worked out. Here is a very rough sketch of the first piece of paper that I stumbled upon. This design should allow the robot to go, forward, backward, left, and right, and even stop with just a single lever, a bunch of gears, and a motor that is continually turning in one direction. Here is how it works:
On the left side, we can see the side view. There are two gears that mesh together on a pivoting bar. Attached to the bottom gear are the wheels. If the lever is pushed all the way to one side, the top gear will touch the drive gear and act as the idler gear, so the bottom gear will travel in the same direction as the drive gear. If the lever is pushed to the other side, then the bottom gear will directly touch the drive gear, and it will travel in the opposite direction. If the lever is put in the middle, then neither the top nor bottom gear will touch the drive gear, and the robot will not move. This is how our robot goes forward, backward, and stops.
On the right side, we can see the front view of the wheel system. Most of our axles are tight square axles that spin with the gears and lock tightly in place, but the axle in our wheels is a loose circle that doesn't turn with the wheel. We can see in this side view that our bottom gear is actually very thick/long, and has 4 rods poking out of either side. This gear will easily be able to slide left and right when the lever is slid left and right. When the lever is slid to the left, the rods interlock with the holes between the spokes of the left wheel, but not the right wheel. When this gear turns, the left wheel will turn, but the right wheel will not. The same applies to the right side. Also when the lever is in the middle, it interlocks with both wheels, allowing the robot to go straight. This is how our robot can turn left and right.
Also, @AaronD'Souza-U04J5CM3T46 and @BrendenD'Souza-U04JC0N6ZC2 uploaded all of our finalized files from Day 1 and Day 2 to the SD card for our printer so they are all readily available to be printed.
We are going on vacation to Florida for 4 days because of a wedding, so we won't get much done then. Hopefully, we can get some CAD files done for the robot when we are sitting in the hotel, but we will be pretty busy and we can't do any printing.
@caleb0i made a… skribbl.io bot that just straight-up draws the word@ScottChiang-U0325L71XQR0Big Milestone! Day 2 of my WHW project
================================
Really productive day today! I was able to get my torso design done and printed (7 whole hours!) and printing the rest of the legs. Hit a big milestone and got the main structure of the robot done 😄
a few hicups along the way (a few micro servos broke) but I got it done!
@ky2006170Ahhhh! Robotics had me crazy today so I couldn’t sit down and CAD a case.
Regardless, I made this cool pivoting gearbox that has a 400:1 gear ratio.
And it was a clear sky day too!
@Daniel0Winter Wonderland - Back Again for Day 2/10! (#hardware-party)
Today has been a pretty busy day for me, so I didn't get quite as much done as I wanted to. Nevertheless, progress has been made and you're here to see it.
First things first, I went through three different motor mount bracket revisions trying to get the angles just right (a tilted motor would lead to belt wear nightmares down the road).
After getting the motor mount sides printed, I decided to knock out a couple easy tasks, so I mounted the battery to the bike, which was easy to do with the water bottle holes already found standard on the bike frame. I also printed the mount for the speed controller (out of PETG for heat resistance) and gave it a test fit on the bike. While the part looks super pretty and clamped on to the frame well, it didn't have the friction to resist my pushing it down the tube. To solve this problem, I'm thinking of lining the inside of the clamp with electrical tape for its thin but rubbery surface.
One more super exciting thing - I got some of my aluminum plates machined at robotics! All I need now is the motor mount plate, which is a little bit more complex with its partial depth cut wings.
Just like the last post, feel free to message me with any questions or input!
CAD for reference
@Captain-A.J.0Assembling the bot! Plan to upload some code for basic function soon.
@Captain-A.J.0Winter Hardware Wonderland Day 1 :winter-hardware-wonderland: #hardware-party
A.L.F.R.E.D ButlerBot (PR here: github.com/hackclub/winter/blob/main/Captain-AJ.md)
Welcome all to the start of a great adventure! I hope everyone is making great progress on their projects. Personally, I have started building my
Autonomous food delivery bot: A.L.F.R.E.D. Which stands for Advanced, Little, Fit, Robot, Education, Device. Today I've just about finished the wheels of my robot, I had some trouble with the suspension due to screw tightness, but all is fixed now! Tomorrow I plan to make a basic
remote-controlled robot for testing. I am currently learning about Arduino hardware and software and will start learning C and C++. That's all for now!
@GauravBansal-U03M3D6RA1K0WHW 1/10 #hardware-party
I researched some inverse kinematic and FABRIK algorithms for my robotic arm! I decided to use a 3R 3D manipulator with one motor turning on a separate axis. Overall, I’m pretty excited to code in IK for the robot arm (and be able to control the arm through input!)
@XhaidenD'Souza-U04HXBNUQRM0Day 1:
As a reminder, @AaronD'Souza-U04J5CM3T46 and @BrendenD'Souza-U04JC0N6ZC2, and I are building a mechanically-codable robot. We are going to have to make a revision to our design. Originally we were going to make it read the input from a wheel with gears, but now we are going to make either 1 or 2 levers that control whether the robot is going forward or backward, and also left or right. Once again there is no coding or microprocessors, all the information for how the robot moves and turns are not controlled by the motor, but by the gears and the physical layout of the plastic pieces. We have a general idea of how this going to work, but we need to do a lot more designing.
We had previously done some testing with tolerances in a gear meshing a couple days ago. Not all of our prints are shown (we had a bunch of fails where the tolerance didn't line up, or the printing didn't succeed, or we replaced in favor of a better design), but pictured in white are our latest version of the Gen 1 gears, motor-axle adapter, and axle. These are printed in the PLA given to us in the box in which we received our 3d printer, and are made with just 20 percent lightning infill on the gears.
Our Gen 2 gears, motor-axle adapter, and axle are the ones that are approaching the level of what we are planning to actually use in our robot. As you can see the sizing completely changed. We are using much smaller teeth. In Gen 1 those 2 gears could only manage a 2:1 gear ratio, but now we have a 6:1 gear ratio with slightly smaller gears. Also, these are printed with PLA+ filament and 50% grid infill so they are much stronger and very high quality. Also, our motor-axle adapter is now tighter on the motor and has a smaller and sleeker design. Once again many of our failed or outdated prints are not shown.
In addition, you can see we set up 100% of our electronics. Just a single motor attached to a battery pack.
@AndrewZhao-U04KN759HPA0Day 1/10 of #hardware-party! 16:1 gear reduction now printing! Should theoretically output ~20Nm of holding torque for a robot arm. Gearbox assembly tomorrow!
@TheScientist1010Day 1 of #hardware-party:
Today I worked on the chassis of the robot. The chassis is updated from Adafruit’s instructions so I had to get a little creative with the roller ball bearing. It’s not drivable yet, but hopefully tomorrow I’ll work with electronics and code. I have a lot of homework today, but I’m glad I could squeeze this in.
@Sean7+Did some work on my Discord Bot stats platform
@jzaleta6Today I selected the Dalle-2 images I'll use for the profilepictureworkshop! I generated them with the app some time ago. I also finished a V1 version of the code, but it stopped working because some errors on the package.json file :npm: . Also I made my own .gitignore file for this project!
@christina6950Coding our robot with Python for upcoming FLL championships. We finished the hack club workshop: Draw Shapes with Turtle
@malted0Attached the motors to the robot chassis without any proper mounting brackets. Tomorrow we’ll mount the arm.
@malted0Built a metal frame for robotics. Super sturdy. Very satisfying.
@jzaleta6I'm going to be making a Slack bot with Bolt! 🤖 Also I learned how to make a VScode theme :vscode: , I was planning to start this first, but I need to think on the colors I'll use so I'll work on the bot first. :salute:
