misspell on "http://shape.stanford.edu/research/swarm/"

I don't know if it your duty. I think think there maybe a misspell in swarm@stanford websites.
But anyway I want to let you know:
Tracking
Our system uses a projector-based tracking system for robot position tracking as shwon below. Using a high frame rate (3000Hz) projector (DLP LightCrafter) from Texas Instruments Inc., a # swequence of gray-coded patterns are projected onto a flat surface. Then, the photodiodes on the robot independently decodes into a location within the projected area. The instruction for setting up this projector-based tracking system is included in the repository.

swequence should be sequence?
