The Cave ROVer Update: Monday the depth bottom scanning Sonar arrives! With an extra special thank you and appreciation to Heidi Ott, Jacqueline Miller, Wm Shrewsbury and On Rope One! Once installed we begin cave & quarry test & training on the dual sonar units. Please consider a donation to The Cave ROVer project, your assistance helps greatly as we push to develop scientific research & exploration robotics focused on cave and environmental science. Some of the focus on funding next, is converting to stainless bearings, and the excitement of developing our very own water analysis array & sampling system.
