Scientists and engineers worldwide are making remarkable advances in robotics, paving the way for transformative applications across many sectors. Recently, developments from South Korea highlight the potential of microrobots, humanoid robots, and wearable technologies intended to assist and revolutionize everyday tasks.
Researchers at Hanyang University have created swarms of tiny magnetic robots capable of achieving complex tasks, such as transporting objects and unclogging tubes. Inspired by the collaborative behavior of ants, these microrobots perform remarkably, with the ability to traverse and pick up objects many times their size. According to a study published on December 18, 2024, by the journal Device, these robots are particularly useful, as they operate under rotating magnetic fields, allowing them to work together efficiently and tackle challenges unattainable for single robots.
Jeong Jae Wie, the study's author, expressed surprise at the microrobots' adaptability and autonomy. "The high adaptability of microrobot swarms to their surroundings and high autonomy level in swarm control were surprising," he noted. With high aspect ratio assembly configurations, these robotic swarms excelled at climbing obstacles five times taller than their height and overcame challenges such as transporting drugs or biological samples.
These microrobots can even form rafts to transport pharmaceuticals through water, showing potential for medical applications, such as providing minimally invasive treatments for clogged arteries. Nevertheless, Wie cautioned, "While the study’s results are promising, the swarms will need higher levels of autonomy before they will be ready for real-world applications" due to their current need for external magnetic control.
While advancements continue with microrobots, OpenAI is reportedly exploring the possibility of developing humanoid robots. Insights from two sources inferred discussions within OpenAI, highlighting the company's interest but lacking detailed timelines or specific use cases. Current humanoid robotics efforts focus chiefly on automizing warehouse tasks and assisting with household chores.
A standout example is the startup Figure AI, which has developed the Figure 02 humanoid robot equipped with AI capabilities for voice command processing. OpenAI has recently invested $625 million for Figure's growth, as the startup achieved recognition for successfully deploying Figure 02 at BMW’s manufacturing facilities, where it was used to move parts efficiently.
OpenAI also invests in 1X, creator of the EVE humanoid robot, which operates on wheels and can reach speeds of nearly ten miles per hour. These developments signify OpenAI's strategic positioning within this domain. A swift partnership with startups like Figure or 1X could expedite their entry compared to building technology from the ground up.
Beyond microrobots and humanoid machines, researchers at KAIST (Korea Advanced Institute of Science and Technology) have developed the WalkON Suit F1—a groundbreaking wearable exoskeleton assisting paraplegics. This lightweight robot can approach users directly and lock onto them, facilitating walking, climbing, and maneuvering obstacles. Kim Seung-hwan, who demonstrated the prototype, shared his personal connection, stating, "It can approach me wherever I am, even when I’m sitting in a wheelchair, and be worn to help me stand up, which is one of its most distinct features."
Weighing only 50 kilograms and powered by 12 electronic motors mimicking human joint movements, the WalkON Suit F1 employs sensors to monitor approximately 1,000 signals per second, ensuring balance and predicting users' movements. This high level of interaction allows users to navigate their environment more effectively.
Another team member, Park Jeong-su, drew inspiration from pop culture, explaining, "After watching Iron Man, I thought it would be great if I can help people with a robot in real life." His innovation has culminated at the Cybathlon 2024, where Kim won a gold medal showcasing the exoskeleton's capabilities.
The fusion of robotics and AI demonstrates limitless potential across several sectors, from enabling medical advancements to enhancing everyday convenience. The rapidly advancing field signifies hope for countless individuals striving for more independent lives.
While there are still hurdles to overcome, such as the need for greater autonomy and adaptability, the promising developments from microrobots, humanoid machines, and wearable technology forecast a bright future for robotic industries.
