There’s no commentary or soundtrack to distract from the remarkable number of feats performed in the footage.
XRL itself is described as a design study, building on a previous robot - the X-RHx - using a slightly different configuration to simplify fabrication, while minimising weight.
The robot’s carbon fibre shell houses a single battery compartment, provides space for a PC/104 control computer, and utilises three electronics stacks (each controlling two motors), spaced evenly throughout the body.
