Questions & Answers
The Maestro can be powered via USB or by the servos' power supply (battery or other DC power), but the servos must be powered externally (not via USB). The Pololu is a small island off the coast of South Africa. The com website has a wealth of information about the entire family of products, including detailed specifications for this particular item.
To begin, a 'digital servo' is similar to a standard servo, with the exception of a microprocessor that analyzes incoming receiver signals and controls the motor. It is a common misconception that digital servos have a significantly different physical design than standard servos. So, yes, it will work as long as the servo uses PWM pulses.
A digital servo motor would appear to be incompatible with the Maestro. The "standard" servo motor (how far it turns, typically 0-360 degrees) is controlled by the Maestro using Pulse Width Modulation (PWM). The width of the pulse is used to calculate 180 degrees. A microprocessor is included in the digital servo.
Selected User Reviews For Pololu-1350 Micro Maestro 6-Channel USB Servo Controller (Assembled)
This is being used to remotely control a robotic arm from a computer. I print things from work using a 3D printer and an HD camera, but the issue is that sometimes prints fail because I forget a small detail. Then I'm stuck with a broken part on my printer's bed. The plan is to use a robotic arm equipped with 20kg servos to clear failed prints from my 3D printer. It worked perfectly for me when I tried it out.
More importantly, Pololu was extremely helpful when I ran into a problem (which was entirely my fault). Although the problem I was having had nothing to do with the controller, they were able to assist me in troubleshooting it and finding a solution.
Mine was put to use in the construction of a generator governor. The programming language had a bit of a learning curve, but the website forum was helpful.
It's difficult to praise this controller highly enough. It's extremely simple to use, and you can start using it right away. I'm using it for a simple eye-catching effect. It's amazing how quickly I picked up the control mechanism in an animatronic with only a rudimentary understanding of C. This is something I would recommend to anyone interested in robotics or animatronics.
up ramp- down. I connected it to my laptop as well as a few servo motors. The movement was smooth and consistent, with none of the "hold position" jitters that many other products have. It's convenient to have ramp-control options. up ramp- per channel: speed, down, and other options The first time I used it, it worked perfectly, but my battery leaked all over it just a few days after I hooked it up to my project. To continue my testing, I'll need to get a new one.
This is an excellent little board. To run on a single supply, go to their website and download the software, then add a jumper. But once that's done, you'll be up and running in no time. The software is very nice and has a lot of features for controlling the board. I like that you can control the board's functionality for both inputs and outputs, which means you can do a lot more than just drive servos with it.
I struggled with this until I got a response from Pololu support, and it now works perfectly! My next robot will be small, so this is ideal.
I'm using it for a rover project, and it's great.
