Techniques for illuminating an interior of an enclosure in an additive fabrication device are described. According to some aspects, an additive fabrication device includes a build region into which source material may be disposed and at least one source of electromagnetic radiation configured to direct radiation onto the source material in the build region to thereby form a layer of solid material from the source material. A first heater may be included that is configured to heat at least a portion of the source material in the build region. In some embodiments, an enclosure surrounds the build region and comprises a refractive aperture. In some embodiments, at least one light source is arranged to direct light into the enclosure through the refractive aperture.

An in-the-wheel suspension system including a drive mechanism for coupling the rotational motion of a wheel rim to the drive shaft of an electric motor and for supporting the wheel rim with respect to the vehicle chassis using one or more springs and dampers. In a hubless version, a spring member supports extend between a frame member attached to the chassis and a bearing member that engages with the rim. In a version used with a wheel hub, the hub is supported by an axle and the spring member supports the axle in movable relation to the frame member. A pivoting support arm that is attached to the axel and pivots about a pivot point attached to the frame member at a location spaced from the wheel axis may be used to support the hub. A Peaucellier linkage may be used to support the axle for movement along a straight line vertical path, the linkage being attached to the frame member at two fixed pivot points. The wheel suspension units perform all the traditional drivetrain functions independently and can be attached to the chassis in a manner that allows for easy removal.

A self-propelled mechanical crawler adapted to move on a medium. One example of such a crawler includes a foot, a wave generator adapted to drive a periodic wave in the foot, and a wave transfer mechanism coupled between the wave generator and the foot. The wave transfer mechanism may be adapted to translate the periodic wave produced by the wave generator into a corresponding periodic deformation in the foot so as to generate forces in the medium to propel the crawler.
