Micro Servo Robot

4 axis robot arm with a small gripper and teach function. (In fact: it is a 3 axis robot)
- please read the full description before ask questions which are already answered -

Arduino mini pro 5V (Uno, Nano .. what ever...)

4 * micro servos 180degrees

4 * 22k potentiometer (10K is okey!)

NmH Battery 4.8V (The Arduino cannot power the servos)

Wires, Button, Switch

Balsa wood, Metal, Plastic

Zip Ties and Glue

Teach mode: After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array.

Play mode: The sketch reads the array step by step and and moves the robot arm. For cool loocking movements i added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed.

Play Mode version 1.1 The gripper input is used to set the delay (0,1,3,15,60,300 seconds) after a loop is done. The switch (it was left from the project start) pauses the robot.

Love this! I was trying to look for ideas to make a small 6 axes but this goes beyond that... you can even teach the positions and run it in auto. This is crazy cool!

I wish i found you sooner, this video is gold for the age

Someone recently uploaded a kickstarter project titled "Micro Servo Robot with Memory" using this exact video.
Since I knew I had seen it before and there's no clear affiliation between you and the project I thought I'd put a little notice of that here in case you want to investigate it any further.

HOLY YOU JUST BLEW MY that was the most efficient way to create, teach and repeat... WOW

This video makes me so excited watching it! I am very proud of you and whoever you got this project idea from. THIS VIDEO ROCKS.

Hey, I’m recreating this project for my final in digital electronics, but instead I have decided to 3d print the base and moving limbs. Viewing this project has really shot up my drive to want to learn more about microcontrollers and whatnot. Appreciated greatly.

Really awesome creating and video, the video editing adds a professional feel to the video even though it's just a proof of concept/fun project. Well done :)

Just saw this featured in another video called "TOP 10 Arduino Projects Of All Time"! The robotic arm following the movement put in by the user alone made me jump out of my seat in utter amazement, and the part where it repeated the memorized movements and kept picking up the bits at the bottom of the slide and dropped them at the top made me plop back into my seat in utter disbelief! Not many videos have achieved that, so congrats on a project well done!

And this is coming from someone currently taking a break from building an automated magazine speed loader for airsoft where u enter a number and just push a magazine's loading port down onto the nozzle to have the magazine loaded to about the entered number (I'm not going for utmost accuracy yet, just trying to achieve an approximate number to the one entered by the user).

can you make a tutorial :'( please

[amitdawar]

At the end... for Coding"

I love that.

[reenuchaudhary]

Please make video on how to make Servo robotic arm

[Weasawll]

I could entertain myself with this for hours...

[ryanoc]

Very cool and inspiring! I wasn't expecting that ending. Great work!

[PriyaGupta-vmpj]

Hiw did you made that learn mode board and can you help me where i can made that learn mode board or some videos like that

[Abdalhkem-vjgc]

هل موجود دراسة النموذج الهندسي المباشر (IGM) والنموذج الهندسي العكسي (DGM) ؟

[walterp]

could you please tell me which kind of potentiometer are you using ?

[nabilandadamslaboratory]

Can you please make a tutorial on this?

[nivaldogeorgjunior]

man, this is fucking awesome, this tec. is very advanced, cientists uses thinks like this to operate objects that can't be touch, gratz, you are a genius, replie this in a scale 1 x 20 and you can work at nasa man.

[AbuleleRozana]

how did you make it to record the manual movement so it can do it automatically
