Team develops mole-bot for drilling, space applicationsMarie Donlon | June 10, 2020
A team from the Korea Advanced Institute of Science and Technology (KAIST) has developed a robot inspired by the African mole-rat and European mole.
The so-called mole-bot is a biomimetic robot that drills holes, mimicking the front teeth of the mole, chiseling away debris and other material.
The robot, which is 25 cm wide and 84 cm long, includes a scapula, fore limbs and an expandable drill bit and features waist inclinable sides that enable the robot to change its direction 360°.
Designed for space exploration and underground applications — for instance mining for coalbed methane or rare earth elements (REE) — the mole-bot includes sensor systems, algorithms and graph-based 3D Simultaneous Localization and Mapping (SLAM) technology that enables 3D autonomous navigation while it is underground.
According to its developers, the mole-bot is capable of excavating three times faster and six times more accurately than conventional excavating equipment and uses its forelimbs to collect and remove excavated soil.
