Dual Servo Driver alternative

Let's Make Robots Projects Showcase

Hi,

My name is Brian and I live in Worthing in the UK. I own a project recording studio which also offers video recording facilities. I’ve never dabbled in electronics but am interested in all aspects of technology - espcially on ‘how things work’ :slight_smile:!

I have a quick question as I’ve done a search of the forum posts but have been unable to find the right answer.

Over at servo city they have a Dual Servo Driver which some videographers have been using to help motorise their sliders - it’s found here: servocity.com/html/dual_servo_driver.html
robotshop.com/en/servocity-manual-servo-driver.html

I was looking at this item supplied by Robotshop: robotshop.com/eu/en/smc-01v2-manual-servo-controller-kit.html

They look pretty similar except that the Servo City one can control 2 servos which the Robotshop one can only control 1, which is fine by me.

The noob question I have is does the Robotshop servo controller control clockwise and anti clokwise servo motion, as the Servo City one does? To get an idea of where I’m trying to go with this project please take a look at this video: youtube.com/watch?v=e2C9QQv2QtY - perhaps someone can offer some better advice as to which components I should go for in order to put this project together?

Thanks in advance!

Hi Coleman, thanks so much for your speedy reply, and for confirming that the manual controller will control the servo both clockwise and anti clockwise.

Basically I have made a camera dolly for DSLR and am looking to motorise video tracking by using the manual controller and servo at one end of the track, together with a pully at the other, joined to the dolly by a thin piece of string/chord.

I’ll take another look at the site to see if I can source everything from here (I originally bought a servo kit with the battery pack from Maplin here in the UK which has some spare parts I can pillage!) so at this point I’m optimistic I can at least get the project under way.

Thanks again - I really appreciate your input!

Of course. On both cases you have a potentiometer which controls the position of the servo. If you want to manually control a servo, you need the controller, the servo and a 6V power supply (4.8V to 6V). Ensure the power supply can provide enough current to the servo. If you can explain the project a bit more, we’d be happy to help.

You’ll need a continuous rotation servo since almost all RC servos only rotate 180 degrees.
