CM510 still not working

You guys have good simulations there, but still the 57,600 kb restrictions for the rs-232 is kind of stunning.

Because this let you control within 25 ms margin for doing all the computing stuff.

If we add 2 more dynamixels this time is still reduced, if we consider 2 ms for reading ports the time required for computing online control laws is very minimal.

Lets put 15 ms for sending informations among robots and the time is still reduced. If we want to compute derivatives integrals and filters you can think that the time for game strategy is like 6500 micro seconds so there is a hardware update to do.

In comparision if it takes to google about 125 ms to reply a ping this gets a physically present robot very fast.

Looking forward to the new vids

2010-01-27T07:56:55+01:00

I have been working with the software and getting some things happening but looking forward to seeing the new vids. You should look to make a series I would love to link them on a site I have been working on. I am not sure if you have seen it www.robotusersaustralia.com I am trying to get a user group going in Australia. See how I go.

Great, back to doing some fun stuff

2010-01-27T06:16:10+01:00

Fantastic, it took me 3 weeks to resolve my issue I fully understand your frustration.

CM510 still not working

I think it is problem with the cable. Try a different cable from distributors and it is work. Let's give more try at home.

Take

Taking laptop and everything to distributor and leave them to help me find out the problem. Maybe a faulty cable. Different version of roboplus or cm510 uart blow. Keep you guys update.

CM510 still not working

I see at least four possible sources of the problem.

1. The CM-510 itself, blown UART or something.

2. The USB2Serial dongle, something physically wrong again.

3. The USB port on the computer is bad.

4. Your copy of RoboPlus is somehow corrupted, have you reinstalled yet?

To determine which one you need to isolate each source from all the others using equipment that is known to work otherwise. For example talking to the CM-510 without RoboPlus on a PC with a real serial port. And, use the USB2Dynamixel to talk to another computer or a modem.

Also at this point you need to consider that one bad component could be blowing out the others.

If the CM-510 worked for the distributor then take it back there and see if it still works.

When things get this bad, chances are that there are multiple problems here complicating the picture.

I might try taking the cm-510 etc. over to a friend's house and see whether it works on their computer.

Or maybe you have another PC laying around you could test it on?

Set to COM 8 result still the same. I tried to buy another rs232 cable today. but cannot find.

Thats correct but you can change it

2010-01-26T14:35:34+01:00

If you right click on the FT232R USB UART then select property

Click the hardware tab

Click on USB Serial Port (COM3) then click on the property button

Click on Port Setting then click on the Advanced Button

Then from the COM Port Number: dropdown select the port you would like

Click OK on all windows and your USB device is now what ever port you have selected.

Give that a go.

Luck has nothing to do with it!

The port number you use MUST be the port assigned to the USB driver that controlls the USB2Dynamixel. This will likely be different from one system to another (mine is on COM5). Otherwise you're pushing bits down the wrong pipe.

ok

2010-01-26T09:22:37+01:00

8 is my lucky number and I haven't tried that yet. Thanks

The other option I did was to go into the device driver

2010-01-26T08:31:37+01:00

In the device driver change the port to No 8. I found when I had it on 3 it would not work.

I am typing v already as you can see but just now response from cm510.
