The $10,000 second prize went to “Skid n’ Bump” from Team Rovetronics out of California. It packs an “all-mechanical, mostly passive” system of cams, springs, gears and shafts that allow a metal probe to detect obstacles and relay the information back to the probe, according to the team. Meanwhile, third place and $5,000 went to Callum Heron for his “direction biased obstacle sensor” (DBOS). It uses a truss with a rock sensor out front, hole sensor legs in the back and a tilt sensor mounted on the rover body.

On top of the designs, NASA and heroX awarded $2,000 for best prototype to Kob Art from Latvia. That group created an impressive full-scale prototype “AMII sensor” that uses caterpillar tracks, a pin ramp, wire rope, springs and other basic materials to help their “rover” avoid rocks, holes and steep slopes. It also offered another $2,000 to Matthew Reynolds for “ECHOS” (evaluate cliffs holes objects & slopes) which uses “mechanical SONAR” to detect obstacles.

NASA awarded honorable mentions to other designs that solved the terrain using other unique and wild ideas. All told, 572 entries from 82 countries were received, with the best being considered for inclusion in AREE’s design as development for the rover continues.

The goal is to have a rover that can survive for months at 850-plus degree F temperatures and barometric pressures 92 times that on Earth. That’s an eternity, considering that the former Soviet Union’s Venera 13 — the longest surviving rover on Venus — only functioned for 127 minutes before dying.
