2020-04-25 17:18:55 -0500 marked best answer Start to teleop My own Robot Model

Hi , I built my own robot model as a urdf file .. Like In this Tutorial

It looks In RVIZ : image description

Now, I want to start to test apps on my model like teleop to start to move it with Keyboard .

What Should I do ?? I think firstly Open a world to Gazebo Secondly, Load my robot on the world .... I DON'T Know HOW ??????????? Third, Start to operate teleop node to start to move .... I WANT a CODE fit to my robot model ?? Actually I can't find a Stack that can operate apps on my robot

thanks

2015-09-01 00:56:34 -0500 marked best answer the best detect and recognition method

Hi all, i am building my vision system to detect and recognition objects ..

firstly, i did object 3D model cloud points Using Roboearth Stack

then tried to detect it with roboearth detector package but it isn't the best because:

  • detect Only texture objects and i have One colored objects
  • red marker not located all the time
  • can't detect the object when turning it reversal
  • i tried to add 2 models to detect them in the same time but it didn't work

i will make some reasoning relations on these objects after that in Knowrob

So, i want a help to choose the best method to detection and recognition objects i am reading in bigg_detector now and searching at others ..

any help to choose the best detect and recognition method ??

2015-08-31 21:15:09 -0500 marked best answer can't detect object model

Hi all, i made 3D object model with roboearth stack like in this tutorial http://www.ros.org/wiki/roboearth/Tutorials/Record%20an%20object%20model

when i tried to detect this object using

rosrun re_kinect_object_detector re_kinect

and

rosrun re_object_detector_gui detect

it begin to read the model then received cloud points and open the detect gui

but No detection happened! No error just receiving point clouds for a long time !! No red mask on the object like in this picture :

Hi,i am trying to record object model using Roboearth stack firstly , i set up my enviroment kinect and marker then, opened openni launch for the kinect and enabled depth_registeration after that i begin to rosrun re_object_recorder record_gui

and the gui opened but can't recieved any cloud points !!

maker detected well and light is fine like in pictures below i decreased distance of marker in gui but still no recieved any cloud point !!

any help ??

and rviz can't recieve any cloud point too !

2015-08-31 20:56:16 -0500 marked best answer kinect or monocular camera ??

Hi,should i use kinect to do a semantic map ? can i use just monocular camera ? what all benefits to use a kinect in roboearth robots that can't done using normal camera ?

and if i want to navigate my robot within a room to reach the table , and begin to infer what is missing components in this table

to do this i must upload object maps of the all table components to Roboearth server using ( kinect or camera ?? ) and this semantic mapping(must be kinect or can use camera) ?? and begin to matching a picture of object with these models in the Database so it takes a pictures when reaching the table ?

all these using of camera in the project make me Confused

thanks in advance :)

2015-06-26 16:57:25 -0500 marked best answer errors in stacks in ROS

Hi, I'm not familiar at ROS errors,, firstly , i installed Roboearth Stack using these four steps :

http://www.ros.org/wiki/roboearth

the result of that : I have the roboearth stack in Home/ros

i made a connection between this and ROS by opening bashrc file and typed "export ROS_PACKAGE_PATH=/opt/ros/fuerte/share:/opt/ros/fuerte/stacks:/home/ros"

and saved

i begin to run re_comm package in roboearth stack but itthrow an error

salma@salma-G31M-S2L:~$ rosrun re_comm run
[rospack] Error: stack/package re_comm not found

i don't know why ??? re_comm not in /opt/ros/fuerte/stacks but in /home/ros/roboearth

why not found ??

and this is the result of rosmake roboearth now

  3. first write my URDF file of my arm or simulate it firstly ??

Hi demmeln, I have finished my robot description files About environment world in gazebo, Not a problem I will use the default gazebo world file The issue now that i want to use the teleop app like that in the turtlebot SDK or whatever on my own robot But i didn't find any apps on a similar robot based on wild thumper base on ROS
