Development Tools

• Eclipse

• ARIA

• Sun Java Development Kit

• Visual Source A

• MS Visio

Team Evolution

Have We Met the Requirements?

• Orientation

• Do users know where they can go?

• Can users relate camera direction with robot heading?

• Are camera controls easy to use and understand.
