Quadrupedal robots have always faced challenges when it comes to navigating slippery or muddy terrain. However, a team of engineers from Tallinn University of Technology (TalTech) in Estonia may have found a solution by studying the movements of animals that thrive in boggy environments. In a recent study published in Bioinspiration & Biomimetics, researchers explored how the design of a moose's hooves could inspire advancements in robotic locomotion. [Related: Why animals run faster than their robot doppelgängers… for now.] Unlike traditional robots, ungulates like moose have evolved to navigate challenging terrains with ease. By closely studying the structure and function of moose hooves, the research team discovered that the split-hooves of these animals play a crucial role in their ability to move through mud and waterlogged areas. The unique design of split-hooves allows for better traction and reduced sinkage, making them well-suited for such environments. The moose legs and the four different synthetic feet tested.

The moose-inspired booties reduced sinkage depth and suction force, while also lowering the robot's energy cost during movement.

The team's study highlighted the potential for quadruped robots to be more versatile and effective in natural environments, opening up new possibilities for applications such as land surveys and rescue missions. With these advancements, future quadruped robots could overcome previously challenging obstacles and contribute to various fields where mobility in difficult terrains is essential.
