hi, Can i install rosserial on ROS kinetic? if yes, can you tell me how please?

hi, i create a launch file that convert depthimage to laserscan:

<launch>
    <arg name="camera"  default="camera"/>
    <arg name="publish_tf" default="true"/>
    <group if="$(arg scan_processing)">
        <node pkg="nodelet" type="nodelet" name="depthimage_to_laserscan" args="load depthimage_to_laserscan/DepthImageToLaserScanNodelet $(arg camera)/$(arg camera)_nodelet_manager">
        <param name="scan_height" value="10"/>
        <param name="output_frame_id" value="/$(arg camera)_depth_frame"/>
        <param name="range_min" value="0.45"/>
        <remap from="image" to="$(arg camera)/$(arg depth)/image_raw"/>
        <remap from="scan" to="$(arg scan_topic)"/>
    </group>   
</launch>

when i run: roslaunch fake_laser_pkg start_laser.launch, i receive this error:

[start_laser.launch] is neither a launch file in package [fake_laser_pkg] nor is [fake_laser_pkg] a launch file name The traceback for the exception was written to the log file what can i do please?

hi, i install ros indigo on my raspberry Pi 3 with rasbian jessie and i follow this tutorial ([link text]) ( http://wiki.ros.org/ROSberryPi/Instal... ) and also, i copy this code on the file "/home/pi/ros_catkin_ws/src/rviz/src/rviz/mesh_loader.cpp":

#  ifdef __arm__                 // fix for ARM build
#include <strings.h>
bool Assimp::IOSystem::ComparePaths(const char *p1, const char *p2) const
{
    return !::strcasecmp(p1, p2);
}
#  endif

and then, i try to run rosrun rviz rviz but i receive

Unable to locate package ros-indigo-rviz what can i do please?

hi , i want to make a robot, i install ros on raspberry and i want to get odometry with ros_arduino_bridge. so i have pololu shield VNH5019 and 2motor metal gear encoder. my problem is electrical, how to connect is how to pololu shield with motors? can you help me please if you have cable schematics please?

i just ask for connexion between motor and shield motor. i have this: My motor has 6 pins:

Red motor power (connects to one motor terminal) 
Black motor power (connects to the other motor terminal) 
Green encoder GND 
Blue encoder Vcc (3.5 – 20 V) 
Yellow encoder A output 
White encoder B output

and my shield:

M1INA Motor 1 direction input A 
M1INB Motor 1 direction input B 
M1EN/DIAG Motor 1 enable input/fault output 
M2INA Motor 2 direction input A 
M2INB Motor 2 direction input B 
M1PWM Motor 1 speed input 
M2PWM Motor 2 speed input 
M2EN/DIAG Motor 2 enable input/fault output 
M1CS Motor 1 current sense output
M2CS Motor 2 current sense output

Hi, Is there any solution to install rosserial on ros kinetic please?

I want to add odometry to Hector SLAM. I have arduino and pololu shield motor with 2 gear motors with encoders. I found ros_arduino_bridge package which contain my shield motos but i don't know how to use it and connect it with hector slam. could you help me?

I install ros kinetic on raspberry pi3 with this tutorial link text and also i clone navigation stack with: git clone https://github.com/ros-planning/navigation.git. but when i run catkin_make, i receive this error:

What can i do please?

hi, i install ros kinetic on raspberry pi3 and i configure kinect with hector slam and all work well. now i want to implémante arduino to make a robot with 2 wheels, i install rosserial and i don't know how can i relate hector slam with arduino to control motors. i know that hector slam provide odometry. can you help me please? i don't know how can i control motors with hector slam

I wrote a node arduino that publish rpm and subscribe to cmd_vel with ros serial, and i can control my robot with teleop_twist_keyboard. and also i create a package with hector slam that visualise a map. now i want to add odometry to hector_slam for autonomous mapping . what can i do please? this is the file.launch of hector slam:
