They have programmed a pair of diminutive humanoid robots called Shafer and Dempster to disobey instructions from humans if it puts their own safety at risk.

A multisensor data fusion method based on Dempster-Shafer evidence theory is described, and an improved algorithm of D-S is put out to solve the dependent information in data fusion.

The theory of evidence, called D-S theory, has great reasoning capacity in the questionably problems, and the dempster rule can provide theoretical foundation for the synergetic disposal of data.
