Robots will soon be able to hike through deserts and beaches as scientists have discovered new ways to compensate for sand’s atypical characteristics.
Today’s humanoids lack the ability to steer through deserts or beaches because the sand particles do not provide a stable enough surface for them to walk, making their feet sink and slip over such loose, uneven terrain.
This disturbs droid's balancing system, which assumes it will step on a hard surface. It becomes perplexed when information from its accelerometers shows that its feet are unsteady, New Scientist reported.
To solve this problem, engineers led by Shunsuke Komizunai of Japan’s Tohoku University in Sendai created an adult human-sized robot foot and made it ‘tread’ with different levels of force in a box full of sand to represent robots of different weights.
The team intends to simulate sand walking in humanoid robots and then regulate control software to deal with different types of sand or loose soil.
