Abstract: A system includes digital servo modules and building blocks that are assemblable in several permutations to construct robotic figures. A central controller communicates with the modules via communication channels, each subdivided into sub-channels. The system utilizes a discovery process wherein the central controller periodically transmits a discovery signal in each sub-channel until a newly attached module transmits a reply to the discovery signal. The central controller transmits position commands to the recognized servo modules and receives position feedback from the recognized modules.

Abstract: A treatment to temporarily block highly permeable areas in a wellbore having a temperature of less than 160° F. A diverting agent, a catalyzer, and a viscosifier are mixed together and pumped in the wellbore where the treatment flows in the most highly permeable areas. The diverting agent then begins to block those areas as the well is treated finally causing the fluid to divert to other now more highly permeable areas of the wellbore. After less than 48 hours the diverting agent degrades sufficiently to restore the permeablility of the wellbore.
