Hello:

Is there a way to extract the wheel odometry from the 440 omni flex vehicle? I.e., the x,y,rotation values at time t?

Thanks!

got it! I think that's probably it...

We did precision tests on a rotating 440 omni flex chassis yesterday, and had some interesting results: 1. We mounted a laser tracker target (+/- .001 in accuracy) on a corner on the flex. 2. We commanded the vehicle to execute a circle. 3. We continuously collected the target data. 4. The omni 440 ...

The problem I think is the vehicle automatically decelerates during the execution of each velocity command, but what we would like is have it maintain that velocity for a duration until a new velocity command comes in. Is there a way to achieve that? Thanks a lot!

We tried commanding at frequencies from 0.5hz to 50hz, but it's never smooth. So for the omni, we can't use acceleration based mapping, correct? The only motion command we can give is velocity (linear, angular, yaw rate)?

Hi, We are interfacing the RMP with our navigation program instead of the joystick. Is there a way to specify how long to maintain a motion command that is sent to the RMP, or instruct the RMP to maintain the motion command until a new command is received? So for example, if we want the RMP to go in...

Hi Patrick:

Do you guys have the URDF (Universal robot description file) for the segway rmp omni 440?

Hi Patrick: I've been charging the batteries for about 5 hours now and both "front" LEDs are red. Also, when i try to power on the machine, the status blinks yellow for about 5 seconds and then blinks red really fast. Also, I got RMP_OCU.py to run, and I selected all the defaults to create the ocu*....

Hi Patrick (?) I'm trying to run RMP_OCU.py, which calls io_usb_cmd.py; io_usb_cmd.py calls _winreg, which I don't know how to import under ubuntu linux 12.04 Additionally, I'm concerned about the .inf driver files for windows; clearly, these won't work on an ubuntu machine (or how do they)? I have ...

OK---got the green power to come on (I hadn't undone the e-stop correctly), but now have a blinking yellow status (perhaps this was because I shorted the d and e stops?). We still cannot get a connection over the OCU demo, and cannot extract a faultlog, although hopefully now that I figured out how ...

Didn't work. I first attached kill switch and that didn't do anything. I shorted the d to e plugs and then attached usb. I only got a fast red blinking status led though. I still tried to run the faultlog extraction, and it failed. Any ideas? No matter what configuration I have tried (no kill switch...
