Need help with robot arm kit

Help & Support Robot Parts
1

Hi. I received a robot arm kit for my birthday. It is called “snam 2800 6 dof robot manipulator metal alloy” . The mechanical arm install guide is in Chinese with illustrations (fortunately). There is also a video, all this is at https://smallhammer.cc/product/snam2800/ . The kit has all the mechanical parts for the chassis (metal structures and screws).
I have never assembled electric or electronic components before. I believe I need
6 servo motors (Tower Pro MG996R - do they all have a rotation capability of at least 180 degrees?)
A starter kit such as Uctronics Primary Starter Learning Kit for Arduino UNO (it has a PCB UNO, a breadboard, a USB cable for the computer) and can be programmed with Arduino IDE software
A potentiometer (would a rotary potentiometer of 10k Ohm do? I am not sure how this will be used but apparently it is needed for the servo motors)

Could anyone confirm that this is what I need to start and make this work or else let me know what is wrong or missing or could be better?
Please enlighten me.

Hi there,

Someone managed to do a similar project here: https://community.robotshop.com/robots/show/arduino-based-controller-for-up-to-6-servos-with-lcd-screen-wip

Hope this will help you getting started.
Note that the servo motor are controlled individually by the 6 potentiometers.

Hello @proven and welcome to the forum!

If you are planning on using 6 Tower Pro MG996R servos with an Arduino Uno you will also need a servo controller or shield because the Uno can only provide 40mA per I/O pin and those servos have the following specs:

  • Running Current 500 mA – 900mA (6V)
  • Stall Current 2.5 A (6V)

You can find some options here.

For the starter kit I suggest this one:


But you can find other options here.

You have some potentiometer options here or you could use a joystick instead like these.

You could also add the LCD mentioned in the example @pjutras suggested!

And you will also need a power supply.

I hope that information can help you out, good luck with your project!
