[ros-users] [Discourse.ros.org] [TurtleBot] Turtlebot2 Square-Path demo

[Ingo Lütkebohle]

The [Turtlebot2 User Guide](https://docs.google.com/document/d/15k7UBnYY_GPmKzQCjzRGCW-4dIP7zl_R_7tWPLM0zKI/edit#), on page 18, show how the TB2 drives a really nice-looking square, with fairly small error.

Is the code to make it drive that square available? Otherwise I'll write my own, but it would be good to have such a nice baseline.

btw, I did check out "motion_square.py" from the kobuki_testsuite. It doesn't look anything like that square. Firstly, it drives round corners, and secondly, it exhibits _major_ angular error. After one square, my TB2 is already about **45** off. Actually, looking at the code, I'm not really surprised -- at the speed it's driving, the low odometry rate is really going to hurt. But I was willing to give it the benefit of doubt ;-)
