Building the MeArm Robotic Arm Version 3

MeArm version 3.0 in Nuka Cola Blue

The MeArm is fun to build and easy to control. The most important step is calibrating your servo motors. To do this you will need to set up your control board first. Links are below which will help you to control your robot and calibrate the all important servo motors.

All kits include the MeArm V3 acrylic frame and servo motors. Choose the right one for you:

  • Kits with controller included — MeArm Robot for micro:bit, Raspberry Pi, and Arduino — plug in and start coding straight away.
  • MeArm Maker Kit — controller not included; bring your own Arduino, Raspberry Pi, or any PWM-capable board. Great if you already have a controller.

The MeArm Maker requires a separate control board, such as an Arduino or Raspberry Pi, that can provide a PWM Signal to control the servos.

Power at 5-6V and around 2-3A needs to be supplied to the servo motors via the 5+ (red) pin. With Ground from the power supply attached to GND. The remaining pins control the servo motors and require a PWN output from a microcontroller. The PWN signal generator needs to be connected to the GND of the power supply to provide the correct reference voltage.
