[ros-users] Problem with canonical_scan_matcher

[#TAN ZHI PING#]

Hi,

I was trying out my pioneer robot using the canonical scan matcher but i realized that the pose2D (odometry) keep on changing despite the fact that the robot remained stationary throughout the whole event as shown in the link provided below.

This video shown the x-axis and y-axis relationship between the odom from the p2os driver (blue) and the pose2D from the canonical scan matcher (red) using rxplot. As i mention earlier on, there is a constant offset in the pose2D causing the position feedback to move away from it's ordinary position.

Is there any way which i used to solve this problem?

With thanks,
Zhi Ping
