One of the requirements that makes a robot a robot is the ability to move independently, and alter its course without outside control. In Aerospace, the change in velocity required to manuever to a higher or lower orbit is simply referred to as Delta Vee. Therefore, The Robot Month of Mobility is represented here by the formula for Delta Vee, and a cool little guy with a flying helmet.

Sales of professional and personal service robots worldwide were estimated to have reached about 5.5 million this year, and are expected to more than double to 11.5 million by 2011, although there is little or no control over how the machines are used.
