I built my own robot model as a urdf file .. Like In this Tutorial It looks In RVIZ :
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 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 :) |
