Uses sonar to detect obstacles. Has a much wider field-of-view than the Sharp infrared distance measuring sensors. Interfaces easily with the Mark III or your own robot design. Comes completely assembled - this is not a kit.

This product is made by Devantech. More information, applications, and code samples may be found on their web site.

An optional SRF04 Mounting Bracket is also available.
