JPL sent the last version of LEMUR up a plateau earlier this year. AI picks a robot its own route, and it uses hundreds of small fishhooks that are embedded in each of its 16 fingers to climb. All while its scientific instruments scanned the stone for ancient fossils. LEMUR has climbed its goal and found fossilized algae balls, once inhabiting the sea previously. Fossils are about 500 million years old, proving the robot's ability to see signs of past life – an important ability for machines to explore other planets.
Although the LEMUR project was over, it was inspired and given rise to other robotic initiatives in the works. The JPL's Ice Worm is adapted from a single leg of the LEMUR robot and is intended to climb the ice walls in frozen worlds, such as the moon of Engradus of Saturn. RoboSimian, originally developed for DARPA's Robotics Challenge as a disaster-prone robot, has four limbs like LEMUR.
The Underwater Gripper is almost one of LEMUR's limbs with the same drawings powered by large fishes built for underwater exploration. Even the helicopter of the Mars 2020 mission will have an adapter of the sickness mechanism from LEMUR's thick legs to cling to the cliffside. This simply means that even though the LEMUR robot itself will not be the gateway to the universe, the technology from the project will help us explore the worlds outside our own.
