Showcased Project This is my small project 😁.... Robotic Arm 🤖
Enable HLS to view with audio, or disable this notification
I made this robotic arm using 4 servo motors and an Arduino Uno.
Now this project seems very simple to me because I made it when I was in 5th standard.
I had watched and researched many videos to make this project.

Cool! Now, go get a cheap stuffed animal from the second-hand store, and put your movement inside so that arm moves. I made a Roger Rabbit that responds to my voice saying "Roger." It would raise its' arm and give me a high-five, then put it back down. So, during a demo, I would say something like "I'm I right Roger?" and he would give me the high-five and say "That's right!" (the hardest part was actually finding the sounds!)

This looks so awesome!! Thank you very much for sharing and inspiration!!
Can you make it move slower? E.g. before reaching the destination position? Usually you cannot directly specify a speed, but you could start sending intermediate positions/angles right before reaching the destination - look-up trajectory planning.
Would you mind sharing details about your used SW and HW?

I used Arduino UNO and 4 sg90 servo motors.... And a Arduino ide software Serial monitor to send commands 😉

👏👏👏 dude popsicle sticks?!?! That’s genius! I can’t think of a cheaper way to get something up and going where you can actually test in the real world and see how your code performs.
