ReachBot animation by Stephanie Newdick and Julia Di
ReachBot is a Phase II NIAC project with Stanford's ASL and with NASA.
The objective of this effort is to develop a mission architecture where a long-reach crawling and anchoring robot, which repurposes extendable booms for mobile manipulation, is deployed to explore and sample difficult terrain on Solar System bodies, with a key focus on Mars exploration. To this end, the robot concept we present here, called ReachBot, uses rollable extendable booms as manipulator arms and as highly reconfigurable structural members. ReachBot is capable of (1) rapid and versatile crawling through sequences of long-distance grasps, (2) traversing a large workspace while anchored (by adjusting boom lengths and orientations), and (3) applying high interaction forces and torques, primarily leveraging boom tensile strength and the variety of anchors within reach.

Minimalist Version RBLite is a very light and compact variation on the ReachBot concept with just one or two deployable boom-arms that are used to position grippers attached to cables.
