2015-04-23 03:31:29 -0500 marked best answer Newbie navigation quesions

Hi,

Few questions about navigation:

1: I have recently read about point cloud to laser scan 2D conversion of data. I already have kinect and 2D Hokuyo mounted on my robot. Does that mean I can completely avoid LADAR and use Kinect instead? To perform, experiments such as mapping, navigation planning.

2: Since Navigation requires accurate odometory data how can we work in case of any hardware wear and tear. For e.g: In case I have two motors of same configuration. After using it for some period there might be some wear and tear in such case how odometory behaves?

3.Can i use ONLY Kinect for mapping and navigation without IMU or 2D laser scanner? OR can i combine the data of Kinect and Laser scanner using Kalman filter? (NO IMU)

Any Help appreciated,

I am not able to install openni package on hydro. Is there any workaround? Since i could see it is not available for the hydro disto.

2014-01-28 17:22:43 -0500 marked best answer vslam beginner

Hello all,

I am using vslam package first time. We have done 2D mapping gmapping to generate a static map. Now, our plan is to generate a 3D static map using a VSLAM. Is it possible to generate a static 3D map using VSLAM? If yes, then what are the steps to do so?

I have gone through SBA and VSLAM packages but unable to understand the process. We have Minoru stereo cam by which we can generate rectified images left/ right and can give it to vslam.

I also tried the sba tutorial. I get below error while compiling the package.

/usr/bin/ld: cannot find -lsba_ros

collect2: ld returned 1 exit status

make[3]: * [../bin/sba_from_file] Error 1

Hello All,

I am not sure if this is a right forum to ask this question.

I want to send a message to any mobile phone using ROS. The application is to notify robot position through text message. Is there any package which can communicate through GSM/ GPRS modem and send text to Mobile devices.

Hello,

I am trying to compile a package containing ROSJAVA related code. I am getting an error while compiling the package as below:

I have checked the cMakeLists.txt which indicates right directory. It is pointing to /bin directory of the package.

Please suggest If we are doing something wrong.

Thanks for the information. The earlier errors were solved. However landed at new errors:

All dependencies are satisfied as per rosmake check.

Do i have to upgrade my Ubuntu from 11.04 to 11.10 since this package is not tested on 11.04?
