UMC – Universal motion controller

At first I created this UMC in order to control my 3D printed servo I made a while back. I soon realised I could create a modular system that could be used in a great veriaty of applications, which would be very usefull for a lot of people.

The UMC allows you to turn almost any geared brushed motor of about 500 watt, 12V into a radio controlled servo. You could for example turn a windscreen wiper motor into a servo. Windscreen wiper motors are pretty strong, affordable, and pretty easy to get by most of the time if you know where to look. If this is not an option for you, you could simply order a motor with a gear reduction attached to it. If you want to use a specific motor for your project you could also create your own gear reduction, perhaps by the use of 3D-printing, like I did with my 3D-printable servo project (project can be found here: https://hackaday.io/project/162855-3d-printable-high-torque-servogear-reduction)

I tried to keep the design of the UMC as simple as possible, it only has 2 IN-ports: Power-in and signal from the receiver (RX), and 2 OUT ports to the servo: Power-out and feedback position signal from the servo. This only makes for 4 connections to reduce the complexity of the system.

I design the controller PCB in EasyEDA and the PCB’s were made by JLCPCB. The controller I used on the PCB is an Arduino Nano. The PCB itself features a reverse polarity protection system, a voltmeter, Power LED, RGB LED and various connectors to the potentiometer, RX and the BTS7960B motor driver. I used the BTS7960B motor driver to control the speed and direction of the electric motor used in the servo.

The case is designed to be snap fit together so that the number of screws required is reduced.
