Yes, the 2x7A Roboclaw should be able to power an RC receiver(anyone I've ever used anyway). If the board itself is working then please check the 5v pins on the board with a multimeter to make sure they are powered. If not, the board may be damaged and need to be sent in for repaired/replacement. If...

Its unlikely the USB functionality will work correctly on a virtual machine. But that doesnt really matter because IonMotion would require the firmware update before it will try to communicate with the board. The order of the Kp,Ki,Kd didnt change in the firmware. It only changed in the arduino libr...

We can solder it back on. I dont recommend you try doing it yourself unless you have a hot air rework station and are reasonably good at soldering. From the picture it doesnt look like any pads got ripped off so it should be fairly simple for us to fix.

Send it in to our contact address.

Thanks for the post and the link. Im assuming htere were two threads in ROS trying to read/write to the serial port at the same time? Or some kind of overlapped serial was being used?

Is there any communications problems when testing with the IonMotion application? If not then the problem is most likely in the ROS driver. As I said in a earlier post in this thread we did not write that driver so Im not sure what could be happening. Note, if the Roboclaw does not reply in several ...

1. Make sure the motors speed is matched. If not the tuning isnt close enough yet. 2. The different may be in the wheel diameter. Its a fairly small difference so I could see that being the case. 3. It looks like you are not sending a second distance command for each motor to stop them. If you dont ...

If oyu are using a single radio per Roboclaw then you dont need to use the multi-unit option or the pullups.

Yes, it can go backwards. Please provide your code so I can see if anything is wrong. Distance should always be possitive and direction is controlled by speed sign when using this command.

Between 10k and 1k. The lower resistance will pullup harder and support faster speeds but in the vast majority of cases 10k or 4.7k will be plenty.

Please show your code. One posibility is if your are using a macro. You may need to put the 65*1000 inside of parentheses, (65*1000).
