An innovative robotic arm that mimics an elephant's trunk.

Researchers at Northwestern University in the United States have developed an innovative robotic arm that mimics the design of an elephant trunk and an octopus tentacle. It stands out for its exceptional ability to twist and stretch while maintaining its strength in executing precise industrial tasks. This paves the way for its use as a safer and more flexible alternative to traditional rigid robots. The new arm relies on advanced mechanical units known as compliant universal joint links, allowing it to bend freely and stiffen when needed to efficiently transfer torque and power, enabling it to perform tasks such as valve closing, light installation, and screw fastening without endangering humans. Dr. Jeffrey Lipton, Assistant Professor of Mechanical and Industrial Engineering at Northwestern University, stated that the new arm is flexible and adaptable like an elephant trunk, capable of generating rotational torque like industrial robots, but safer in human-inhabited environments. This development represents a breakthrough in the field of hybrid robotics, combining the strengths of rigid robots known for their power and speed with soft robots characterized by their ability to adapt and safely interact with humans and delicate objects.
