OK. Thanks

Thanks jwatte. For Moving Threshold, what value do you recommend? Do you set the Moving Threshold and Return Delay Time of all motors within the same robot to the same respective values? Do you...

Thanks. These are all very good questions that I need to think about. I plan to use U2D2, XH series, Protocol 2.

From the emanual you linked, the Return Delay Time "delays transmitting the Status...

Thanks.

I see many factors are involved. Is there a formula to calculate the recommended baud rate given the control loop frequency and the number of servos? Ideally I hope to get 1ms respond...

Thanks KurtEck. By long wire, how long are you talking about?

Hi, it looks like some members in the forum use baud rate of 3M BPS. Is there a reason for that if 4M or 4.5M BPS are available? Is the higher the baud rate always the better since it allows higher...

Thank you.

Thanks jwatte. My simulator has 0 as the center and +- value degrees to indicate the amount of turning and whether it is turning clockwise or counter-clockwise.

In previous projects, I used...

Hi, I have question about converting between rotational angle in degree and positional values accepted by dynamixel.

I have not built a robot but different motors can be oriented differently...

Thanks. What do you mean by "twang"? For this test, since there are so many positions, is testing each motor under 2-5 different positions sufficient?

As for the torsion springs, don't they...

Hi jwatte. Thanks for the suggestion. I did a test on two motors separately. They behaved as following:

I connected a motor to a PC and scanned it under Dynamixel Wizard. The software found it. I...

Hi, even with the same model, some units generate some sound when they are powered (no load and not being turned). I just plugged them to a controller one by one and assigned ID and Baudrate under...

Does it work well? Is it straightforward to install?

Thanks Kevin.

Thanks

Is it recommended to always update the firmware upon receiving the dynamixels?

Thanks jwatte.

Hi jwatte, McMaster sells so many different types of cable sheathings. Which one do you recommend?

Thanks KurtEck and jwatte. I am trying to decide between three batteries. They all have the same mHh. One has C=75 but 20-30g heavier. The other two have C=60. At such high C values, although the one...

Hi, when choosing LIPO for MX-106 class high toque motors, is there a range of C values that I should be looking for? Is there a threshold C value above which there is no advantage or perhaps even...

Thanks KurtEck.

Hi, when receiving expensive Dynamixels, what should one check to make sure that they arrived without any issue? Is updating the firmware the first thing to do?

Thank you

Thanks. I made custom cables many years ago. I know that I am not very good at it.

Is it a bad idea to change the connectors soldered in the hub or controller board instead?

What is the name...

Hi, I need convertible cables longer than the 180mm one sold by Robotis. is it easy to remove the connectors from Robotis current cables for the X-series and older cables with MOLEX connectors? Any...

Thanks KurtEck. Yes, I worry that accidentally I may connect the + pins of the batteries together and damage those expensive motors. So better to use only one battery for all the dynamixels?

Thanks. I know the concepts of serial and parallel connection of batteries as shown below.

However, I...

Thanks jwatte. Am I correct that I also have to connect the ground of the controller, PC or SBC and the batteries for the dynamixels?

Hi, I recall reading something like if two batteries connecting to a system of dynamixels within the same robot are not of the same capacities or at different charge levels, then the dynamixels could...

Thanks. I will check with customs.

Thanks KurtEck.

Is there any point to buy all required servos together at the same time?

Hi, I see some users posting photos of their components before making their robots. What are the pros and cons of buying the required number of Dynamixel all at the same time vs. buying in 2-3...

This is a very nice robot. At 1:22, I see a Trossen powered hub on each side with a thick red and black wires. Where are they connecting to? Are they connected to each other and then to a battery for...

Thanks jwatte. I have successfully removed the horn. When I did that, I heard a pop sound. Hope it was just a sound caused by the horn being separated from the shaft.

Thanks. I need to slowly digest your procedure. Maybe 3D print a thick plastic with three or five holes.

I don't have M2 screws with me so I will need to order online. Giving the outbreak...

Thanks tician. I don't know if the X-Series is similar. What do you think of the tool used in this video? The idea seems to be similar.

Hi, I inserted a horn on the X-series motor shaft. Then, I found that I was supposed to put a washer in between first. In this case, should I leave the motor as is? Could removing the horn easily...

Nice. Is there a reason you used PETG rather than other materials? What places would need enough plastic?
