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.

[@GaryParkin]

@@krishmaher107 Yes i did. That was a few years ago and as I remember it worked fairly well. The downfall was the servo's. The robot is just too large and needs stepper motors. that's where I left it when real life crept in.

[@Pauljohn696969]

Thanks very much for putting this out there. I have purchased all the parts I didn't have and am in the process of 3d printing the arm components for the arm as I write this. My only comment beside to praise you for you excellent efforts is to suggest that you include printing instructions for your future projects. I'm printing at 22% fill and .1mm quality and I hope this will be OK for strength. I suspect this will be fine but the MG996R servos seem to have a lot of power! Paul.

[@MrTyugar]

Could you tell me about quality of print with your settings? Is it ok for strength?

[@partivkartikeya2269]

4:26 ... Can you plz add the video of the connecting the wires.

[@rajavelbhasker]

unfortunately this is not working. After printing all the parts and putting them together as per the electronics schematics. It does not work. The Mobile app is able to connect to the bluetooth module and shows the status connected but when the sliders are moved the servo moves very slowly. Also tried with 1 servo the problem is the arm shows some movements when only 1 servo is connected. when the slider for elbow is moved the arm shows little movement and when the shoulder is slided it shows some movement. When only 1 servo is connected not sure why all the sliders are working for 1 servo. Is there any upgraded code to get this working ?

[@akashk7219]

Is the dimensions wrong or we're not able to implement Bluetooth connection??

[@nobodystudio5295]

The basically the code is designed to act on any input it receives

[@nobodystudio5295]

Hey there, what is the maximum weight the robot can lift? Awesome project

[@pavanarjun4259]

It can lift upto 1.5 kg to 1000 kg but it depends on weight and size of the undefects physical configuration, construction and drive system.✨🤖

[@AhmedObiedBahubaishi]

I JUST REALLY NEED THE DH PARAMETERS!!! Thanks very much for the detailed tutorial, I followed along and the robot was amazing. I am working on development of the project; adding the capability of inverse kinematics for this robot. Giving it the cartesian pose relative to frame zero being below the base. I searched through detailed blog and opened all the links related to the design, but none of them was including this information or the file in a format that makes measuring the dimension possible. Measuring the 3D-printed parts does not give an accurate enough estimation.

[@gmodesike]

Can this robot be programmed by moving the arm around by someone?

[@ethangilbertmedia]

Sounds like a great idea and would be good for on the fly programming

[@MightyTechGuy]

You are the best person on youtube! Thanks!!!

[@HowToMechatronics]

Thanks!

[@ikkeaninono3860]

thanks for the detail and easy-to-follow information! I really appreciate it.:) One question, is it possible to scale up the whole size with same components?

[@rylandallas9907]

Can you run a Honda engine in a full sized truck? Probably but is going to fail haha

[@TheMus3L]

i thought about the same, it depends on torque of the servo that rotate whole arm vertically (the one with rubber), it has probably 10kg/cm so it can hold 10kg weight on roller of radius = 1cm(Torque = 10*9.81*0.01*1=0.981 [Nm]). For example if your arm have center of mass 15cm from servo, it weights 250g and angle is 65 degrees Torque = 0.25*9.81*0.15*0.9063= 0.333 [Nm]. So you can calculate max size of arm if you take extremal position, but well... it gonna take you some time.

[@seekertosecrets]

I have a couple of questions about this setup and I hope that it can somewhat be applied to the project I'm working on. I'm in the process of making an animatronic bird for this project. The bird in question will only be able to move its head and its wings created with 3d Printed parts. 1. With just the wings, how much weight can the MG Servo motors can handle? I need the motor to handle roll and pitch movements to potentially move 360 degrees for the roll, but only 90 degrees on the pitch. Each wing is not going to be heavy. No more than 55 to 66 grams. 2. On the pitch movement of 90 degrees, would it better to setup a pulley belt system to move the wing, like an arm, 90 degrees? 3. Since I can't use the app for this setup, is there another way to control the servos remotely?

Hi Thank you for this great project. I am battling to get the app to work with robot. I see you have a updated app that is used when adding wheels. Will it be possible to send me the Code and the App details. Thank you

[@HowToMechatronics]

Hi, there are many things that could go wrong in this situation. First you must check whether you have a proper Bluetooth communication, whether your modules work right. You can do that with another simpler code just to test whether you have communication. Then you have to check whether you are getting any values from the app into the Arduino so that send commands to the motors to move. There is no guarantee that the codes that I provide will always work on your setup. It worked for me, and I showed how I did it. From there you should find a way how to make it work on your setup.
