Before long robots will be capable of trekking through deserts and beaches since scientists have discovered innovative ways to compensate for sand's atypical features.
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.

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.
