Drawn to scale

The robots side by side at their true relative size, as their source models are posed.

10 cmLeKiwi265 mm tall10 cmLeKiwi265 mm tall
Specimen renders from each project's source files, scaled so a meter is the same length for every robot (measured at each model's center: the renders are perspective views, so the scale is exact there). Heights are the models as posed in their sources. Not drawn: Bambot (the render places some parts apart from the body, pending a reviewed pose).

Side by side

Every figure is read from each robot's record, with its source; a cost keeps the currency the source states and its basis.
