Hi I am running gazebo and player with the attached files. The display window shows that the robot moves certain distance and stops.But the robot's pose is getting updated (as i can understand from the values printed). In fact I didn't understand the use of "set_cmd_vel" function properly. Can anybody help me out of this please ????

Hello, Could you clarify the problem you're having? A quick scan through your code shows that you first set a forward velocity of 10 m/s, a sideways velocity of 5 m/s, and a rotation rate of 20 degrees per second. Then you stop all linear motion and start rotating in the opposite direction at -20 degrees per second, and finally you stop the robot completely. If this is not what you are seeing, then could you describe what Gazebo does? -nate On 5/13/07, HEMANTH <hem...@st...> wrote: > > Hi > > I am running gazebo and player with the attached files. > The display window shows that the robot moves certain distance and > stops.But the robot's pose is getting updated (as i can understand from > the values printed). > > In fact I didn't understand the use of "set_cmd_vel" function > properly. > > > Can anybody help me out of this please ???? > > Waiting for your replies > > > -- > ************************************************************* > K.HEMANTH > COMPUTER SCIENCE AND ENGINEERING(DUAL DEGREE) > ROLL.NO# 200402017 > ROOM.NO# 399(OBH) > CONTACT NO# 9849229262 > IIIT--HYDERABAD. > > EMAIL: > hem...@gm... > hem...@ya... > hem...@st... > ************************************************************** > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.

Hey, Thanks for your reply.Your analysis helped me.I got my problem solved. But my original problem is to simulate a vehicle on a terrain and get sensor readings (using laser). But all the robots i tried (pioneer 2at,segwayrmp,etc) are falling down at a slope. I tried using carchassis but i am not able to get its odometry. So how can I solve this ? I mean , can I get a vehicle which can walk properly on a terrain or isthere any way make the car chassis run properly ? Waiting for your reply.
