Tried running pi tracker on turtlebot, but recieving error!! How can I fix it?

edit

Hello there,

I'm new to ROS groovy and turtlebot. I'm trying to run the tracker command from pi tracker package on my turtlebot, but I get an error of "error transferring IMU from gyro link to base foot print". I want to control the turtlebot using hand or foot gesture. My guess is the robot model is not correct. Any idea on how to get around this issue?

Thanks.
