Well that just proves that the interpretation of the rules is incorrect!
WALK
verb

gerund or present participle: walking

1.move at a regular pace by lifting and setting down each foot in turn, never having both feet off the ground at once.

The walking mechanism was sufficient to please the Guinness book of records, when they presented Scuttle with the world record for "fastest walking Robot" 2001!

As above the rules are there to stop the use of DrillZilla type systems that are nothing like that of Anarchy or Pilgrim!
