Amazing Robot Controlled By Rat Brain Continues Progress

Some technologies are so cool they make you do a double take. Case in point: robots being controlled by rat brains. Kevin Warwick, once a cyborg and still a researcher in cybernetics at the University of Reading, has been working on creating neural networks that can control machines. He and his team have taken the brain cells from rats, cultured them, and used them as the guidance control circuit for simple wheeled robots. Electrical impulses from the bot enter the batch of neurons, and responses from the cells are turned into commands for the device. The cells can form new connections, making the system a true learning machine. Warwick hasn’t released any new videos of the rat brain robot for the past few years, but the three older clips we have for you below are still awesome. He and his competitors continue to move this technology forward – animal cyborgs are real.

The skills of these rat-robot hybrids are very basic at this point. Mainly the neuron control helps the robot to avoid walls. Yet that obstacle avoidance often shows clear improvement over time, demonstrating how networks of neurons can grant simple learning to the machines. Whenever I watch the robots in the videos below I have to do a quick reality check – these machines are being controlled by biological cells! It’s simply amazing.

Breakthrough gives artificial muscles superhuman strength

Putting “socks” on artificial muscles made from inexpensive materials helps them produce 40 times more flex than human muscle, a global research project has found, featuring researchers from the University of Wollongong (UOW) at the ARC Centre of Excellence for Electromaterials Science (ACES).

UOW researchers from ACES joined with international partners from the U.S., China and South Korea to develop sheath-run artificial muscles (SRAMs), that can be used to create intelligent materials and fabrics that react by sensing the environment around them.

It builds on the work over the past 15 years by researchers from UOW and their international colleagues who have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line.

An artificial muscle device that produces force 34 times its weight

Soft robots, medical devices, and wearable devices have permeated our daily lives. KAIST (Korea Advanced Institute of Science and Technology) researchers have developed a fluid switch using ionic polymer artificial muscles that operates at ultra-low power and produces a force 34 times greater than its weight. Fluid switches control fluid flow, causing the fluid to flow in a specific direction to invoke various movements.

KAIST announced on the 4th of January that a research team under Professor IlKwon Oh from the Department of Mechanical Engineering has developed a soft fluidic switch that operates at ultra-low voltage and can be used in narrow spaces.

The results have been published in Science Advances (“Polysulfonated Covalent Organic Framework as Active Electrode Host for Mobile Cation Guests in Electrochemical Soft Actuator”).

Harvard’s robot exosuit aids Parkinson’s patients walk without freezing

Researchers from Harvard SEAS and Boston University reveal its transformative effects, offering newfound mobility and independence for individuals with this debilitating condition.

The wearable tech successfully eliminates a common symptom called ‘gait freezing’ to restore smooth strides for Parkinson’s disease sufferers.

Cyborg computer combining AI and human brain cells really works

A new biohybrid computer combining a “brain organoid” and a traditional AI was able to perform a speech recognition task with 78% accuracy — demonstrating the potential for human biology to one day boost our computing capabilities.

The background: The human brain is the most energy efficient “computer” on Earth — while a supercomputer needs 20 mega watts of power to process more than a quintillion calculations per second, your brain can do the equivalent with just 20 watts (a megawatt is 1 million watts).

This has given researchers the idea to try boosting computers by combining them with a three-dimensional clump of lab-grown human brain cells, known as a brain organoid.

Bionic artificial skin with a fully implantable wireless tactile sensory system for wound healing and restoring skin tactile function

Although artificial skins can facilitate the healing of damaged skin, the restoration of tactile functions remain a challenge. Here, Kang et al. report an artificial skin with an implantable tactile sensor that can simultaneously replace the tactile function by nerve stimulation and promote skin regeneration.

Fourier Intelligence launches production version of GR-1 humanoid robot

Fourier Intelligence has been manufacturing exoskeletons and rehabilitation devices since 2017. The Singapore-based company launched its first generation of humanoid robots this year, designated the GR-1.

The humanoid platform includes 40 degrees of freedom distributed throughout its body, which measures 1.65 m (5 ft., 5 in.) in height and weighs 55 kg (121.2 lb.). The joint module that is fitted at the hip of the robot is capable of producing a peak torque of 300 Nm, which allows it to walk at a speed of 5 kph (3.1 mph) and carry goods that weigh 50 kg (110.2 lb.).

Making the leap from exoskeleton development to humanoid design is a logical progression, as the humanoid platform shares many of the mechanical and electrical design elements that Fourier developed for its core product line. Actuation is a core competency of the company, and by designing and building actuators, it claimed that it can optimize the cost/performance of the system.

Welcome to the Cyborg Era: Brain Implants Transformed Lives This Year

This year gave rise to an incredible mix of brain implants that can record, decode, and alter brain activity.

It sounds like déjà vu—brain-machine interfaces also lived rent free in my head in last year’s roundup, but for good reason. Neuroscientists are building increasingly sophisticated and flexible electronic chips that seamlessly integrate machine intelligence with our brains and spinal cords at record-breaking speed. What was previously science fiction—for example, helping paralyzed people regain their ability to walk, swim, and kayak—is now reality.

This year, brain implants further transformed people’s lives. The not-so-secret sauce? AI.

Incredible bionic arm powered by A.I. and THOUGHT 🦾 | BBC

This is a great invention.

Professor Mike Wooldridge asks: what is artificial intelligence? He compares how AI works and learns with how the human brain functions. Exploring the roots of AI, Mike reveals how Alan Turing devised the Imitation Game – a test of whether a machine answering a series of questions could pass as a human. The audience in the lecture theatre play a real-life version of the game to find out if AI can pass this test today. In this lecture, Mike examines real-life neurons in action and explains how artificial neural networks are inspired by neural structures in the brain. To demonstrate how AI learns, we watch drones as they are trained to recognise and fly through structures in the lecture theatre autonomously. AI exploded into the public consciousness in 2022 with the release of ChatGPT and boasts around 100 million monthly users. Mike unravels the mystery of how large language models like ChatGPT work, and he finds out if one day this technology — along with a whole suite of different AI tools — will allow us to understand the animals we share this planet with. The Christmas Lectures are the most prestigious event in the Royal Institution calendar, dating from 1,825, when Michael Faraday founded the series. They are the world’s longest running science television series and always promise to inspire and amaze each year through explosive demonstrations and interactive experiments with the live theatre audience.\
