01 / STUDY

Mechanism and experiments

ReachBot uses extendable booms as supports, with microspine grippers contacting rock. The reported 2024 field tests in a Mojave Desert lava tube used a single boom and gripper mounted on a tripod.

02 / CONTEXT

Test conditions and scope

Field tests used teleoperation to evaluate the single boom and rock grasping. Lab prototypes, field component tests and planetary-cave concepts represent different stages.
