Artificial muscles propel a robotic leg to walk and jump

by

Researchers at ETH Zurich and the Max Planck Institute for Intelligent Systems have developed a robotic leg with artificial muscles. Inspired by living creatures, it jumps across different terrains in an agile and energy-efficient manner.

Inventors and researchers have been developing robots for almost 70 years. To date, all the machines they have built – whether for factories or elsewhere – have had one thing in common: they are powered by motors, a technology that is already 200 years old.

Even walking robots feature arms and legs that are powered by motors, not by muscles as in humans and animals. This in part suggests why they lack the mobility and adaptability of living creatures.

ETH develops ‘lighter, safer, more robust’ artificial muscles for robots

by

Researchers at ETH Zurich have developed artificial muscles for robot motion. The researchers say their solution offers several advantages over previous technologies: it can be used wherever robots need to be soft rather than rigid or where they need more sensitivity when interacting with their environment.

Many roboticists dream of building robots that are not just a combination of metal or other hard materials and motors but also softer and more adaptable. Soft robots could interact with their environment in a completely different way; for example, they could cushion impacts the way human limbs do, or grasp an object delicately.

This would also offer benefits regarding energy consumption: robot motion today usually requires a lot of energy to maintain a position, whereas soft systems could store energy well, too. So, what could be more obvious than to take the human muscle as a model and attempt to recreate it? [Read more…] about ETH develops ‘lighter, safer, more robust’ artificial muscles for robots

Human-like hands for robots move one step closer with Italian scientist’s invention

by

An Italian scientist has invented a robotic end effector that could bring the goal of robots having human-like hands one step closer.

Corrado De Pascali and his colleagues on the Italian Institute of Technology have unveiled an end effector which uses tiny, 8-gram actuators to power many different joints in the complex component.

According to report in New Scientist and several other outlets, the actuators – although small – can actually lift “1,000 times their own weight”. [Read more…] about Human-like hands for robots move one step closer with Italian scientist’s invention
