Small Body Orbiting

Microspine Grippers, 2011 - The video presents microspine-based anchors being developed for gripping rocks on the surfaces of comets and asteroids, or for use on cliff faces and lava tubes on Mars. Two types of anchor prototypes are shown on supporting forces in all directions away from the rock; greater than 160 N tangent, greater than 150 N at 45 degrees, and greater than 180 N normal to the surface of the rock. A compliant robotic ankle with two active degrees of freedom interfaces these anchors to the Lemur IIB robot for future climbing trials. Finally, a rotary percussive drill is shown coring into rock regardless of gravitational orientation. As a harderthan-zero-g proof of concept, inverted drilling was performed creating 20mm diameter boreholes 83 mm deep in vesicular basalt samples while retaining 12 mm diameter rock cores in 3-6 pieces.

Landmark-based Spacecraft-orbit Determination, 2004 - Landmark-based spacecraft-orbit determination. Left pane: Imagery with detected landmarks shown. Red = rejected as outlier. Green = accepted. Right pane: Recovered position overlaid on ground-truth trajectory. Vision-based position errors are shown for each frame. (1:15)

Nanorover Technology, 1998 - A description of electronics technology development in preparation for the MUSES-CN flight mission. Shown are techniques to sense wheel terrain contact using capacitive proximity sensing, and those to reduce dust build-up through electrostatic rejection. Also described is the development of new miniaturized electronics, called Widget Boards. (6:32)
