So would calculateNewPosition function include something like sin? How would I create a function that maps time passed to a sinusoidal velocity profile? Also, would it work best to apply this...

I'm using usb2ax so direct serial communication

Ok I understand, though im having some difficulty finding out how I would make my while loop update at 60hz (every iteration of the while loop writes a position). If I want to do it your way, would I...

So I understand a bit more, I'd do that in something like a while loop in python I guess, but how would one "increasingly" raise the position gaps each iteration? And what if going to say position...

What do yo mean? could you explain further or give me an example?

Hello again jwatte and thanks for your response!

I fear that solution may not work so well since I'm working with AX-12As as well.

Hey guys, I am using Python and running some dynamixel motors at fairly low maxspeeds (12rpm or so). I am interested in smoothing out the motion at the beginning/end of a write command.
...

How can I make sure it's never over 16V? If I'm using a 15V dc power supply, wouldn't that mean it cant ever go over 16V?

I am designing for the 1:5. I don't want to make a complex power circuit...

Alright, I'll try to stick with a 12V dc thanks

In this document from trossen http://www.trossenrobotics.com/images/productdownloads/dynamixel_guide.pdf it says that he nominal voltage is 11.1-14.8V

I need every bit of torque I can get out of...

I want to use a 15V (resistor to 14.8V) power supply to power a MX-28T daisy chained with two AX-12As. I can't think of any good way to power the AX12A's with 12V and the MX-28Ts with 14.8V. Would it...

Hello, I want to do some motion analysis/planning stuff with dynamixel servos, ros and gazebo.

I'm fairly new to this stuff, what ros distribution will make my life easiest?

thanks

okay cheers!

What do you mean? Sorry.

The dynamixels aren't being loaded by gravity (planar motion). I should be all good with jwatte's suggestion, right?

Is there a way, if I have say a link attached to a dynamixel servo, to give a slight "push" to that link and have it assist me moving that link until I let go? Like it senses im trying to rotate/move...

Alright thanks guys!

It sounds like the USB2AX is easier to work with and reduces the amount of electronics a lot. Wouldn't the Arbotix-M be connected via USB too via FTDI? Can you think of any advantages/disadvantages...

Alright I do have a main computer board, similar to the jetson tk1 - Do you then think arbotix-m is a good user friendly/easily integratable choice as a microcontroller to control 3 or 4 dynamixel...

I'm looking to create an autonomous 3DOF arm single horizontal plane-oriented arm, and I think I'd like to use ROS for the movement. (Mainly moving the arm to a specified location in a point cloud...

Building an arm using all three of these motors, is the integration/programming going to be a challenge using a servo not in the MX series>
