Claim 19:
20. A fail-safe controlled motion capsule, comprising:
the capsule swallowable by an animal;
a shape changing gel enclosed in a container in the capsule;
the shape changing gel variably expanding from an initial state to a three-dimensional volume, in response to nonionizing radiation energy;
a controller;
at least one nonionizing radiation energizer;
the controller variably energizing with nonionizing radiation the shape changing gel;
a first fail-safe system:
whereby de-energizing of the shape changing gel results in the shape changing gel contracting to the initial state, or substantially close to the initial state, sufficient to allow the controlled motion capsule to pass through a body tubular structure without a problem;

a second fail-safe system:
a feedback system that detects at least one special case, the at least one special case being the shape changing gel poses a risk to the body tubular structure;
at least one special compound incorporated in the shape changing gel, wherein if activated the at least one special compound breaks down the shape changing gel;
the controller, in response to the feedback system detection of the at least one special case, activates the at least one special compound.
