This project was a great way to start learning programming robotic arms. Eventually, I was able to develop my own code and add Bluetooth to control the arm wirelessly. Thanks for sharing this project and I hope your channel grows even more!
Thank you so much for your comment. This really encourages me to publish more content! I am glad if this video inspired you to tackle this project and to learn coding robots. This is awesome! The theme of my channel is "Design > Print > Build > Code > Play > Repeat". I plan to publish more content like this over time. Stay tuned!
This video is awesome! I would appreciate it if you could please make videos that explain the code in more detail. I find the hardware and connections to be easy, however I wish coding in the context of robotics can be explained more in depth. Thank you for sharing this wonderful project, I will definitely make it!
Thanks for your comment. I like your idea. There are plenty of Python tutorials for beginners but learning by practicing is more fun. Robots are a cool way to learn programming. This robot was initially used to introduce my 12 years old son to coding with Python. Kids really like when they can see that code can move things outside of the computer. See you soon on YouMakeTech!
Thanks for watching! If you enjoyed this video, take a look at YouMakeRobots: th-cam.com/video/ZrdnrW7ZXsA/w-d-xo.html . This is a 3D printed robot kit which allows you to design & build you own robots!
Hi, I am trying to make this project and I noticed you mentioned the Arduino pins that you used. However, I would like to know which pins are specifically connected to which servo, like which pins is the servo on the base or the claw or the two hand servos connected to, as this will allow the connections to match the code you used I would appreciate the help. Thanks for sharing this project.
Hi, looking back at the code, I used pins 3,5,6 9 and 10. Pin 10 is for the servo which opens/closes the gate, 9 for the servo of the hand. 3 is for the azimuth / base, 5 for the first arm and 6 for the 2nd arm.
Thank you for helping with the hardware. I had one more question about the software. I uploaded your "servotest" file after installing pyfirmata and it worked. However, your "RobotArmDemo" file doesn't seem to work as it references the "RobotArm class" from the other file despite that the code says "from RobotArm import *". Sorry I am new to object oriented programming and classes and I tried googling how to use a class from another file into this one. If you could please link a video that shows how to do this or just explain how, I would really appreciate it. Thanks!
You're welcome. Make sure you copy the 2 files RobotArm.py and RobotArmDemo.py in the same directory and that you cd to that directory before you start the Python interpreter. If it still does not import, try this : stackoverflow.com/questions/4142151/how-to-import-the-class-within-the-same-directory-or-sub-directory
Awesome video, thanks for sharing. I have two questions if you don't mind: 1. It seems to work fine without any external battery, which really puzzles me. Since an Arduino UNO can only deliver 500mA I wonder if the one used in the video is an especial one that can provide much more power. Second question, about the method "MoveTo", the numbers represent just angles for each servo, or an (x, y, z) coordinate in space? Again, keep up the good work.
Thanks for your comment. Regarding your questions: (1) It only works with a few micro servos because the Arduino Uno can only deliver 500mA. For more servos or bigger servos, you are right: an external power supply is required (2) In the current code, the coordinates are angles in degrees not x,y,z. In order to target x,y,z, a mathematical model must be added (Inverse Kinematic Model), which computes the joint angles from the desired x,y,z position in 3D space. Thanks for watching!
Btw. I am watching your channel. Looks great! MicroPython is something I am really interested in too. If only you could provide english subtitles, your knowledge would reach a wider audience
@@andresmata8859 Cool, and you make games for Amstrad CPC too. CPC 6128 was my first computer. It is great! I found somebody in the world who shares the same passion as me!
Sir, I don't understand exactly what you're trying to do. Do you want to program 100% in Python or do you want to interface a microcontroller with a computer program written in Python? Also take a look at this video: th-cam.com/video/TYPN3kH7gNU/w-d-xo.html . It is possible now to program microcontrollers directly in Python! Not only this is is easier to do, but you can do it interactively which shortens development time
@@wahidali4378 I don't think so. PIC microcontrollers don't have enough power to run the Python interpreter directly like in the Raspberry Pi Pico. I was using Arduino but switched to Pi Pico because it is so convenient to be able to program 100% in Python
Yes, you can access the whole hardware in Python 3 with the Raspberry Pi Pico. And interactively! You also get interrupts + timers + dual cores! I find this pretty amazing for a 4 $ chip! I haven't tried image processing on Pi Pico.
Try to connect only one servo to the arduino pin 9 as shown in the video a nd see whether you can move it with the servoTest.py script: github.com/YouMakeTech/RobotArm/blob/main/servoTest.py
@@YouMakeTech it worked with servoTest.py but still didn't work with RobotArm.py, when i type robot.goto() and write the numbers the code runs but not the robot, plz i need you're help this robot is my project for school
@@abode5820 Try to run RobotArm with only one servo connected and see if it works. Maybe your 4 servos draw too much current and cannot be powered by the arduino. You may need to power the servos with a separate power supply
@@abode5820 Which servos do you use? The arduino can only supply 100mA of current which only works for a couple of micro-servos. If you need more current, you have to power the servos with a separate 5 volts power supply or battery
Nice!, can you help me with something? I have connected my servo to pin 9 but when I'm trying to rotate the servo, it doesn't work... It just adds some degrees to the motor.. Thank you
Hi, you need a trajectory generator like this: github.com/YouMakeTech/YouMakeRobots/blob/main/MotionProfile.cpp or github.com/YouMakeTech/micropython-robots/blob/main/TriangularMotionProfile.py . Instead of moving from one position to another in one step, you need to slew at constant speed. This is how smooth motion is achieved with commercial robots. Unfortunately, the hobby servos used have a small deadband and never move perfectly smoothly
Votre video a ete tres enrichissante et comprehensible. Pour ceux qui ont decide d'ituliser raspberry pi au lieu d'arduino, dans quelle partie je devrai reediter?
To control servos with the Raspi, the easiest way would be to use a PCA9685 board to connect the servos. Take a look at learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspberry-pi
This one is 3d printed: www.thingiverse.com/thing:1015238 . You can buy a robotic arm from Sunfounder: www.sunfounder.com/collections/new-products/products/arduino-robot-arm-kit . Or better, you can buy a 3D printer! Not only you can use it for this project but for many others! And the Ender 3 is very affordable
Absolutely. With the exact same hardware, you can program the Arduino with its own language which is very close from C++. The issue is that it is very hard to program the motions because it is not interactive. Each time you want to change a motion, you have to recompile the code, upload it to the Arduino, fail, try again. Very time consuming... The benefit of using Firmata is that you can interactively send commands from the Python prompt. It is easier to get the motions right. And the Python language is easier to learn than C++ for beginners
Take a look at www.arduino.cc/en/reference/board . The pins are shown on the Arduino board. Pins are where the wires are connected to the Arduino board. They are of various types depending on the type of signal: Analog, Digital, Digital PWM and do on
Hey my Guy, I changed ur code a little bit and now i am finished i think mine is the better one for controlling the robot so i can send you the code so you can make a video about it or something like that and it shouldnt be a disrespect
This robot is perfect to get started. It was used to initiate my 12 years old son to robotics and programming. I am currently working on a 3d printed robot kit. With this kit, you will be able to build any robot you like, from a simple robot to a complete humanoid robot. Stay tuned!
Can I offer some wisdom? Turn down or delete the music in the background. I actually can't call it background as it is as loud as the narrator. Why? I can only guess. I have worked, with, trained and entertained many thousands of people. The only time music was required was during DJ services at parties, etc. I want to learn this stuff but everyone has the same guide apparently. I also noticed the louder the music, the fewer subscribers. Couldn't make out what you said, and can't give a like. But I won't give a dislike either.
You're absolutely right. The DJ music was a failed attempt to make the video a bit more "entertaining" ! I think I improved this in my recent videos. TH-cam is a learning journey for me!
Do you really need hc-12? For short distances, HC-05 is much easier to use (no change in code). Your computer communicates with the Arduino over Bluetooth. See create.arduino.cc/projecthub/millerman4487/view-serial-monitor-over-bluetooth-fbb0e5
