Copy paste error?

[galou]

First of all, thanks for contributing this code to the community! I'm planing to drive a PhantomX with ROS and will probably make use of you simulation for the development.

I just noticed something that looks like a copy-and-paste error:
walker.py: l. 88, f3.scale *= -1 should probably read f4.scale *= -1.

Hi,
You're welcome, and your contributions appreciated.
The walk algorithm has been ported from that of our darwin_gazebo package with minor adaptations so a copy-paste error is likely, however the correct version is to remove both f3.scale and f4.scale changes. Actually the straight walk is not that straight, so if you get a better one that'd be great!
