I have just bought a MCD EPOS Maxon Motor and I would like to run it with ROS. I have used this package, and whenever I try to run

roslaunch epos_hardware example.launch

it gives me this error:

started core service [/rosout]
process[epos_hardware-2]: started with pid [15836]
process[controller_spawner-3]: started with pid [15853]
[ERROR] [1461483492.673722502]: Could not find motor

[FATAL] [1461483492.673989258]: Failed to initialize motors

My device's serial number is 0x60002998. I have also tried with what the answer for this question suggests and I have also given permission to all usb. I'm using a Ltd FT232 USB-Serial.

The only different thing I have from the previous question's author is that I'm using the last version of EPOS (MCD), but I think they work in the same way.

Thanks!!!

HOW have you solved it?

ow can I make this project run property?

https://github.com/mugenZebra/CE216-p...

I've done

cmake ../

and then I do

make

but I get this error:

I've ROS Indigo

Thanks!!

How can I fix this error? (when I do roslaunch)

Error [Param.hh:154] Unable to convert parameter[broadcastTF] whose type is[string], to type[b]

Thanks!!

I'm trying to control a 6-wheeled robot and I'd like to control each wheel independently. I've tried with skidsteercontroller (but I'm afraid that's only for 4 wheels) and with diffdrivecontroller (but the problem is that each pair of wheels works in the same way, and I want ALL the wheels to run independently...) Is there any other controller useful for my case? Or at least, is there any ros_package of a 6-wheeled robot example(similar for example to r-hex robot ?

I'm using ros indigo

Thanks a lot!!

How can I (having a 6-wheeled robot and using the DiffDrivePlugin6w from hectorgazebo plugins) make that each wheel subscribes in a different topic: Now I've been able to make that all the wheels move at the same time (they are all "answering" to the cmd_vel topic), but I'd like something like cmd_vel_front_left topic,....

  </plugin>

Thanks!!

I have just installed Gazebo following the on-line steps explained here
and once i've done the first one: I try to open gazebo typing gazebo and pressing Intro but nothing occurs.... (the $ symbol apperas in the next line as if the previos action was completed, but no window is opened with gazebo interface)

(i have Ros Jade, just if it is important...)

Thanks a lot!!!!
