Community Question

I was about to order a couple of servos from the EZ store, but was shocked to see how much the shipping was from China. More than the cost of two servos. So i did a quick search and found Brookstone is offering buy one get one free on certain bits, ie servos orientation sensor etc. I ended up doubling up the servos for the same price from the EZ Store. Not sure how long the sale will last.

The
EZ servos would not work at all with the board.



voltage problem ? I tried an EZ-Servo HD with 5V 10A, and the servo didn't work.

As far as a digital servo being quiet my experience has been opposite.



my comment is related to the digital too: more noisy and use more power.

... We will be offering full range digital servos made specifically for ezrobot in our store in the new year.

The micro servo we currently offer is actually a digital servo. Digital servos don't provide feedback to the controller unfortunately they just have higher resolution, holding torque, and are usually programmable to take different timing signals.

All EZ-Robot servos in April will be a new digital version. They include safety shut off and do not emit any noise when holding position. Jeremie and James have just completed their final testing this week. Significantly different compared to the analog versions. Also, they are better aligned from factory and generally do not require servo profiles.

... EZ-Robot has been working on a torque monitoring servo that also contains stall detection and heat detection. It's a digital servo as well. We have quite a few prototype, but still have a few more hurdles to accomplish before it is available to the public. ...

the last post is really good news, it will solve common problems.

I'm working on a solution to manage the stall detection (Gripper), and is not easy with an analog a servo.

*EDIT*
Gripper has a micro servo (digital)

Thanks for all great info. I checked and you are correct. It's a power issue. The board only supplies 5 to 6 volts directly to the servo. I would have to power the servo separately to use them.

Interesting that the micros are digital and the big ones are not. But explains the price differences in the two.

Yes, from my model airplane experiences with digital servos, they can be noisy because they a always busy centering themselves when idle. Just takes a little getting use to it, but sure are nice. Digital servos are the preferred servo for many rc airplane/helicopter competitions ( I do rc aerobatic pattern flyig myself). So will seem to be a good fit for robots ;)
