Modular bodies

Modular bodies allow some robots in Zile City to replace damaged components and change physical capabilities. Roger uses this extensively after Weyland rebuilds him with interchangeable limbs. Salvaged parts can restore movement, supply weapons or create a configuration suited to an immediate problem.

Reconstruction in the field

A lost arm can be replaced with another usable component. The parts need not match in size or function, and a complete humanoid assembly is not always required. Roger can remain active as a detached head and reconstruct around it if useful components survive nearby.

Interchangeability does not prevent damage. Heat, attacks and the available wreckage can make finding a workable replacement an urgent part of an encounter.

Recovering equipment

Magnetic joints in a replacement torso designed by Peavy let Roger target limbs and draw them toward himself from a distance. They add reach to his existing ability to exchange components, helping him recover equipment when collecting it by hand is difficult.

The upgrade changes how Roger obtains parts; it does not first make replacement possible.

The range, power requirements and exact targeting constraints remain unspecified. Drawing a component toward Roger does not establish that the torso can tear a still-attached limb from another robot.

A separate hijacking ability obtains a susceptible enemy body by having it install his thrown head. It depends on the target's vulnerability to a signal, not merely the physical fit of its components.

Roger can register recovered parts at synthesizers and select combinations of limbs for a replacement body. Attaching a limb in the field modifies the body already in use; obtaining a new body from a synthesizer is a different operation and raises separate questions of personal continuity.

Developing configuration systems

Proposed light, medium and heavy categories affect speed, force and stability. Heavy arms on light legs could combine powerful strikes with rapid movement but create an unstable weight distribution.

Further proposals allow a head to connect directly to a hand, leg or weapon arm. Some arrangements would permit hopping, while others could fire from the ground. Practical console interactions may require at least one functioning hand. These control and balance details remain in development, and they do not establish a universal specification for every robot body.
