  1. First of all thanks for the great Project! However, I am struggeling to get the servos to run proberly. The servos are shaking, small movement back and forth. I am not able to control them normally. I've tried already to change the baudrate, check the data which is sent to the Bluetooth Module and i've used a Mega as well (somebody in the comments mentioned it). Any ideas what could be the problem? Thanks

  2. Thank you very much for this video! I just want to know if you shut down the Arduino and start it again it can save the position of the robot?

  3. Hello sir,
    Thanks for sharing the project. It's a great help in showing to new buds what automization is.

    With your help I am helping my 7 year old son in learning automization or at least making him familiar with.

    Thanks a lot sir.

  4. This is the first project you made that I ordered all the parts for and I'm going to build it. Thank you for sharing your STL files, I have the Creality CR10S model and I love it. Isn't it nice?

    Love your ant too. Oh, also, I've been developing Android for about 3 years now with Xamarin, and you introduced me to MIT App Inventor. What a cool program! I was up and had an app running in 15 minutes as opposed to Microsoft VS that took 3 days to get all set up.
    Thanks again – Subscribed.

  5. Thank you very much sir. My project is almost done, the program is good (just change little bit). Hope you all the best with all your content

  6. Thy so much dude, i learned a lot in ur tutorials, this year i will going to high school and i will write in mechatronic

  7. hye i am facing some problems in using sg 90 servo motors whenever i send signal through bluetooth app and code provided the servo motor only moves back and forth and does not react to desired position pease help me to resolve this problem

  8. Can you make this with cheap ebay arm? And also how to you copy the codes for arduino software? Sorry in advance for sounding stupid

  9. How do you attach the servos to the pieces? The attachments I have for the servos have holes that are too small for any screw to fit. Do your attachments have bigger holes in them? How else can I attach them to the parts?

  10. the servos come with screws but the soildworks parts have no screw threads so how do you connect them?

  11. my question is the following for a bluetooth hc-06. this code would work or would have to make modifications to the code

  12. How to connect sg90 servos for wrist roll, pitch and gripper? what servo attachment is used? (hub, horn, etc.)
