Hi. May I ask your help?

I want to install this in my computer to use EPOS motor controller with ROS . Because I need for my undergraduate course graduation Maybe I thought, I installed EPOS Command Library well.

Because, When I test ' $sudo ./HelloEposCmd -n 2 ' 2015-08-17 15 30 53 The result seems well done.

But, My problem is I don't know the progress on installing this ROS node pkg..

Just Do I need to copy this git like

$ cd ~/catkin_ws/src/ $ git clone https://github.com/RIVeR-Lab/epos_hardware.git $ cd epos_hardware

........ and then?? What I need to do?

My condition is 64 bit ,Unbuntu, ROS, indigo

Did you try just typing 'sudo apt-get install ros-indigo-epos-hardware'?

Ah T.T Thank you. I 'm really waiting your answer.

Yes, I tried . But I got msg that " can not find package"

So, I have tried to clone this git src and make . I don't know how to solve this .

Do I need to add another repositroy address?

I also did 'sudo apt get update && sudo apt get upgrade

Uhm... I tried it in another my computer and It was installed . I don't know what is different each other.

anyway, Is it done only if using 'sudo apt-get install ros-indigo-epos-hardware ??

Can I just use it???? I want to use ' step mode ' . I don't understand how Can I configure with it.

$ rosrun epos_hardware epos_hardware_node motor_name1/position_regulator

??Do I have to write like that?

I am not sure if this is the proper place for this but you basically need to read and understand everything here: http://wiki.ros.org/epos_hardware

It is indeed installed only by typing that line if everything goes well. About the usage you need to know how ROS and more specifically ros_control works in order to make it work. You can try to run the example provided by the author by typing: 'roslaunch epos_hardware example.launch'.

If you are looking for some documentation on the package maztentropy is right that you can find it here. If you are simply looking to control the motor and don't have a reason to use ROS than I suggest you use Maxon's Library directly (http://www.maxonmotorusa.com/medias/sys_master/root/8815100788766/EPOS-Command-Library-En.pdf). Especially if you have not used ROS or ros_control before and you don't need to use them. Also the reason why you were probably unable to install it on one of your computers was that you had not followed the ROS setup instructions.
