Programming a Wireless Robotic Arm

[@javidx9]

I developed this further to allow Twitch Chat to control the robot arm in real time! It was quite a funny and surreal experience. You can view that here: www.twitch.tv/videos/410107783 I will of course upload this to javidx9extra in due course too.

Maybe, maybe not. There's a lot of OpenGL material available already. I dont know what, if anything, i could add!

[@ronerickson8083]

If you can code a robot's ROS then place my debug code on the 1st Line of code in the system then run it through like any other line of code: . . . . .. . . .. . .. Force = [F=m(2385)]; . . . .. . . . . . You can also run this on any line in the system's language. It runs the SOST properly.

[@kodiererg]

I like how much more intelligent this is than 99% of the micro controller tutorials on RUclips

[@daanielacosta2395]

"Several robotic arm projects" so later on, we can expect to see forward and inverse kinematics, or more advanced topics on robotics?, this was a great video BTW, and the next sounds very interesting.

[@Toothbrush099]

Knowing almost nothing about hardware, I thoroughly enjoyed this. Keep up the great content!

[@paladin1147]

Holy moly, this is amazing. The way you thought out at the Communication bit was so incredible
, thinking that might be a problem later on and finding such a simple solution was very thoughtful. Thanks for the video. A lot of components yet super smooth.

[@barmetler]

This is _way_ cooler than just using an arduino! Really happy to see some hardwarey stuff on this channel.
Keep up the good work!
Also, It would be cool if you could do a reverse kinematic model in the olcgameengine and just animate the absolute position and rotation of the grabber using keyframes and interpolation.

[@kodiererg]

You could program an arduino with AVR studio and no or few libraries and feel super cool.

[@barmetler]

@@kodiererg There are many challenges you can set yourself, but I just felt like this is a cool one. But low level arduino programming (with inline assembly for example) sounds like a lot of fun as well, you're right

"because it is a high-level video I won't go into too much details regarding the nature of the signals that beign transmitted" and proceeds to explain bit layout in package bit/byte transmission speed difference, etc :D
I remember I tried to do it in high school as project for computer science course.

[@javidx9]

lol, well I didnt want to detail the electrical specification of UART and subsequently RS232 or similar is what I was referring to XD

[@raulchavez1838]

You should really make a tutorial after OOP for C++, most programming tutorial end around there. I really enjoy your videos, and would love to see a mid to advance tutorial from you. I know C++ is ground upon, but it is most university students learn first.

[@javidx9]

Hi Raul, what kind of things would you like to see "post-OOP"?

[@raulchavez1838]

@@javidx9 I apologise for the late response. I got no RUclips notification, and the email was sent to a sub folder automatically. Honestly it would help alot if you had playlist of easiest to hardest. That way you can continue to make amazing videos, but we can grow as coders by following and investigating our selfs.

I like the idea how you controlled those servo/stepper motor via settings slider, you can save those settings for recording steps of servo/stepper motor just like in fanuc industrial robots rather than controlling it manually, you know what i mean. Nice project

As for the twitch chat, maybe add a simple abstract picture of the robot next to the sliders in the ui? I think it makes things a bit more clear. Maybe with arrows as well.

Suggestion for the next update, control the robotic arm with a joystick.

You should have a look at ESP32, way more horsepower than Cortex M cores (Wifi and BLE embedded, so no need for modules)
Oh and it's Visual Studio-compatible if you use the native IDF

[@magnuswootton6181]

PLS ANSWER->>> Would this arm collapse if you took the power off the motors?

[@javidx9]

Of course, they are pwm servos with reasonably low ratio gearboxes. It would collapse but slowly.

[@javidx9]

Unless the arms have brakes or extremely high ratio gearboxes, they will always settle into a relaxed state

[@magnuswootton6181]

just helping out. (u dont need my help, but just trying to be fair.) i dont know for sure, but the "jitteryness" and oscillations could be caused by the motors backdriving each other as they are trying to settle on their absolute rotational position. that little sound at the beginning that u heard. (that wasnt really in the video) was them causing an oscillation with each other. then might be a solve which is better than PID controllers... and its actually simulating it physically, if u can handle the headache.

[@magnuswootton6181]

@@javidx9 thanx for info.

[@javidx9]

The motors have no closed loop control so PID isn't an option in this case, when I'm designing real robots naturally they all have full dual loop control and are very stable, but this toy doesn't, and it's not bad to be fair, it's jitteryness is in part to supply collapse, getting the motors moving sinks a whole load of current briefly, which naturally diverts from the others, this is in a way a feedback loop until things settle into equilibrium. I need a better power supply!
