Thanks for the contribution. The guide is well-structured and discoverability is set up correctly in both navigation and the Sensing index.

One minor cleanup before merge:

• Please normalize the title punctuation by replacing -- in "Motion Capture Systems -- Setup Guide" with a more standard separator (maybe just "Motion Capture Setup Guide"?), and keep it consistent across:
  • _data/navigation.yml
  • wiki/sensing/index.md
  • wiki/sensing/motion-capture-system.md front matter title

After that, this looks good to merge.

Remember to resolve merge conflicts with master branch with a merge or rebase.

Hi team, good article. One small change on content side:

• In Hardware Setup > Camera Mounting, add some information about the recommended configuration for multiple cameras (eg. evenly spaced out along each wall, one in each corner, etc). Note that the 2-3m height recommendation can be common for humanoids/drones, but entirely dependent on the application (eg. an isolated robotic hand or surgical instrument can be in a testing space no bigger than 1m on each side), so revise the suggestion to be appropriate for the application.
