Hello, I´m a teacher on a High School in Germany, exactly in Bavaria. I´m very, very impressed of Your project and I want to make it with my pupils. Is it possible if You press the button on the gripper and simulate a movement with the small robot included the potis that the robot can repeat this movement automatically? Is there an additional button necessary for save and repeat the automatically movement? Kind regards Michael

@@connorribera4198 11v should work for the arduino, but if the servos are 4.8v-7.2v, you should step down voltage going to them. for battery current, you have to look at the stall current of a servo, and add them all up, and add extra buffer.

First of all i wanted to thank you for the thorough walk through and the detailed explanations. This is my first "big" project in electronics i am doing. I have a small question that might come off a bit unknowledgeable. For this project i need a power source/supplier. How do i pick my power source? Do i get a battery? an adjustable power supply (that seems the best choice but also most expensive). How do I know what Voltage and current i need to supply in this type of project? Thank you very much!

hey dude, awesome stuff. Just wondering what can you change to make the join movements smoother and more accurate?
@80xdplays8812 күн бұрын
I think using a belt and pulley system would be much smoother, the downside being how much more complex and prone to breaking that would be, alternatively you can use a chain and gears (I've used both for robots before personally the extra smoothness isn't worth it in my opinion)
@555amryАй бұрын
Hello, I’m Abo it to put everything together. Just wanted to ask, when you plug the Arduino in to upload the code, do you also plug in the power supply at the same time so the servos work, or will that be too much voltage and fry something?

Me and a couple friends managed to assemble this whole thing for a school project, however we're running into an issue where when we upload the code, none of the other servos move as the potentiometer does. We tested all of the potentiometers' connection without plugging into the servo driver and it reads, but as soon as we hook everything up to the driver only the microcontroller for the gripper functions properly. Some help would be greatly appreciated, thanks for the great tutorial!

I've built the project. sadly its not working as expected currently. only the base servo and the shoulder servo and hand servo are moving in response to the controller. however the movements are a bit erratic, some movement mimics the movement of controller but then the servo will move the other way and sometimes the servo is sort of twitching even when the controller is perfectly still I have tested continuity for all the wires coming from the pots right to the arduino so ruling out any failed connections. Also the hand servo is constantly in motion until i press the button and it stops until i release again. i'm assuming i've wired this the wrong way round. i worked around this by changing the code to if(pushbutton == HIGH) instead of LOW Has anyone else had similar issues? I'm new to wiring and electronics so any help would be appreciated. Is there any program i could use on my arduino to see if my arduino is picking up the changing values of my potentiometer signal. Many thanks

Thank you so much for this video! I've learned so much and you are amazing for keeping this open source. I'm super new to electronics so I ran into an issue with the micro servo for the gripper. When I press the button the servo doesn't move. It will move the 90 degrees to close at the beginning (line 28 of the code) but won't move beyond that. When I switched it out with a regular servo (MG996R) everything ran fine and the button opened/closed the gripper. Plus the pin 13 test light turns on/off when the button is pressed, so I'm confused. Wiring isn't the issue either since when I connect the micro servo to the pins controlled by a potentiometer, the micro servo runs perfectly. I've tried to troubleshoot: I've assigned the micro servo to different pins on the driver board, re-copied the code over, and, checked the voltage with a multimeter (it was within the correct range for the servo), but I'm still sort of stuck. Any help would be appreciated. Thanks!
