2015-10-13 12:17:45 -0600 commented answer Errno2 xml syntax in launch file

Sorry, my mistake...(there was a space between launch and xml that i missed while editing file)...thank you, your solution worked....thanks...

2015-10-13 12:14:04 -0600 commented answer Errno2 xml syntax in launch file

if i execute ls, it says "ls: cannot access (file path): No such file or directory"..i tried for other existing launch files, and i get the same file path(successful access) as entered...what could be the problem?

2015-09-21 12:24:28 -0600 asked a question confused between two tutorials regarding ros_control

hello sir, i'm currently learning ROS and Moveit through tutorial series. however, when i came across ros_control, i got two tutorials - links as - 1) http://gazebosim.org/tutorials/?tut=r... and 2) https://github.com/ros-controls/ros_c... . ofcourse, i understood(with my little understanding) that first meant when i want to setup with gazebo and second with moveit(ros), but when i came across 'standard used by moveit as well as gazebo', i got confused. does both tutorials end up with same result(package structure)? if not, then, in what way do they differ? thanks.

2015-09-21 12:08:46 -0600 asked a question Integrate actual robot into moveit(other way than ros_control?)

hello sir, as a beginner, i just completed tutorials and found out the solution pretty near to it. but however, before proceeding, i think there must be another simpler way to do it....and here is my problem- i have written topics which when called without arguments gives joint positions, and if called with arguments, executes requested joint positions(though it should be service(to confirm for correct execution), i havent written so, thinking i might require to access them in multiple ways)(through these topics, i can only control joint position and speed(neither effort nor other parameter)) now how can i integrate into moveit? i mean, should i have to write ros_control for it or simply i have to publish(through a node-topics) to topics(like joint states), somewhere in moveit infrastructure? thanks.

2015-09-21 09:49:23 -0600 commented question Having a working MoveIt! config - what's next?

have you found solution for it? if so, can you please give detail steps for it....

2015-09-21 09:30:03 -0600 commented question how to get output from moveit? which topics need to be subscribed?

rostopic echo /move_group/fake_controller_joint_states will give you what you want, when you execute moveit demo.launch.....but this is not the correct way to solve this problem..unfortunately, i'm still struggling to get correct solution for it....

2015-09-21 09:21:53 -0600 answered a question Establish interface between ROS and Matlab toolbox files(dll and header)

i have found it. from matlab 2015a onwards, mathworks have included ros support into main matlab package.

2015-09-11 02:51:14 -0600 marked best answer Which tutorial should i follow?

hi sir, i'm trying to understand and make robot using arduino. however i'm confused to learn which tutorial should i follow? i mean should i go for catkin tutorials or for main ros one? at present, i have installed indigo and ubuntu 14.

2015-08-23 12:51:21 -0600 marked best answer Is there any graphical software package to make urdf file?

i want to make urdf file for the robot. the problem is, adding each constraints, geometry dimensions manually in a text file is a bit long process. isnt there any graphical tool(CAD software package) through which i can make my robot urdf? i have already seen for solidworks add-in, but i want alternate solution. thanks

2015-08-23 12:32:53 -0600 asked a question Establish interface between ROS and Matlab toolbox files(dll and header)

currently, i have a robot(articulated 6dof arm)(not listed yet in ros supported robots, anywhere) which came with some dll and header files. as per their(robot provider) package description, all we have to do is to copy those files in appropriate folders of matlab installation(windows system) and we get standard commands to operate robot through matlab(with their standard functions).

so the problem is, how can i do it in ubuntu(linux system)? what i mean is, how can i operate the robot through ros? let us assume i have written all the necessary code to talk with this system(let us say in c++ or python), how can i make interface with those robot package files?

initially i thought about copying those dlls in linux matlab installation but later i understood, thats not possible. i also thought(and read) about using winros and winelib...but how can i do it?(what i mean is these are emulated systems, then how can they communicate with the ros running on ubuntu?)

is anybody have "EXPERIENCE" with this kind of stuff? please share...

hello, i have been wondering and searching for robot configuration/controller files for scorbot ER4u, already worked on for it. is anybody have worked/has experience over it and like to share configuration files...

2015-07-28 10:49:03 -0600 edited question need package/library to actually control hardware....

hello, currently, i have setup the manipulator using moveit setup assistant. what i want exactly is the package/library which now can take input from moveit joint states, and give the output in either parameters like velocity, direction...or even the pulses to control the hardware motors(stepper motors in my case). (in short, i wanted package/library similar to that of servo example mentioned in rosserial_arduino). is there any package/library/program available to satisfy my this hardware level need? (a hardware controller may be)....or do i have to write it down for my specific hardware(i use microcontroller as arduino) from scratch.....?. i'm on ros indigo, ubuntu 14.04. thanks.

2015-07-28 10:47:24 -0600 commented question need package/library to actually control hardware....

not yet.what i have figured out until now is to write custom node which will talk with joint states and with that of microcontroller stuff.....not sure is it the correct way or not....
