What are the latest advances in robotics research?


Robotics research is constantly evolving, with new advances being made constantly. In 2023, there have been some particularly exciting developments in the field.

One of the most significant advancements in robotics research is the development of robots with improved dexterity and manipulation capabilities. This progress is largely attributed to artificial intelligence (AI) and machine learning (ML) breakthroughs, which enable robots to learn from experience and improve their skills over time. As a result, robots can now perform complex tasks previously thought impossible for machines, such as picking up delicate objects, assembling complex structures, and even performing intricate surgical procedures.

Another exciting development in robotics research is the emergence of robots that are becoming more natural and intuitive to interact with. This is thanks to natural language processing (NLP) advancements and computer vision (CV), which allow robots to understand and respond to human language and gestures. As a result, robots can now engage in natural conversations, follow human instructions, and adapt to their environment, paving the way for more seamless and human-like interactions between humans and robots.

1. Improved dexterity and manipulation

Researchers have developed more dexterous robots capable of manipulating objects in more complex ways. Dexterity is the ability to handle and manipulate objects skilfully and nimbly. Dexterous robots are essential for various tasks, including manufacturing, assembly, and surgery. In recent years, researchers have made significant advances in developing more dexterous robots capable of manipulating objects in more complex ways.

One of the key factors that has contributed to these advances is the development of artificial intelligence (AI) and machine learning (ML). AI and ML allow robots to learn from experience and improve their skills. This means that robots can now learn to perform complex tasks without being explicitly programmed, such as picking up objects with different shapes and sizes.

Another important factor that has contributed to advances in dexterity is the development of new sensors and actuators. Sensors allow robots to perceive their environment, while actuators allow them to interact with their environment. New sensors and actuators are making it possible for robots to perceive their environment with greater precision and interact with their environment with more finesse.

As a result of these advances, there are now robots that can perform tasks that were previously thought to be impossible for robots. For example, some robots can assemble complex objects, such as LEGO bricks and Ikea furniture. Some robots can perform delicate tasks, such as surgery and jewelry making.

Here are some specific examples of recent advances in dexterity and manipulation:

  • Researchers at MIT have developed a robot hand that can pick up and manipulate delicate objects, such as grapes and eggs. The hand is made of a soft material that conforms to the shape of the object it is grasping. The hand also has sensors to feel the object and adjust its grip.
  • Researchers at the University of California, Berkeley, have developed a robot to assemble a Rubik’s Cube. The robot uses a combination of cameras and sensors to perceive the Cube and a robotic arm to manipulate the individual pieces. The robot can solve the Cube in about 20 seconds.
  • Researchers at the Swiss Federal Institute of Technology in Zurich have developed a robotic for delicate surgery. The robot uses a robotic arm that is equipped with a variety of surgical instruments. The robot can perform tasks such as cutting, suturing, and tying knots.

2. More natural and intuitive interaction

Robots are becoming more natural and intuitive to interact with. Using Natural language processing (NLP), robots can now understand and respond to voice commands, control smart homes, play music, and even provide customer service. Some robots can understand and respond to text messages. These robots can provide information, answer questions, and offer emotional support.

Thanks to Computer vision (CV), which has made it possible for robots to perceive their environment and interact with objects more naturally and intuitively, robots can now follow human gestures. These robots can assist humans in painting, assembling furniture, and even surgery. Some robots can recognize human emotions. These robots can provide companionship, offer emotional support, and even detect signs of distress.

Here are some specific examples of robots that are using NLP and CV to interact with humans more naturally and intuitively:

  • Pepper is a humanoid robot that SoftBank Robotics developed. Pepper can recognize human emotions, follow human gestures, and engage in natural conversation.
  • Baxter is a humanoid robot that Rethink Robotics developed. Baxter can understand and respond to voice commands and can be used to perform a variety of tasks in factories and warehouses.
  • Nao is a humanoid robot that Aldebaran Robotics developed. Nao can recognize human emotions, follow gestures, and engage in natural conversation.
  • Atlas is a humanoid robot that Boston Dynamics developed. Atlas can walk, climb stairs, and even jump.

3. Increased autonomy and decision-making

Robots are becoming more autonomous and capable of making decisions on their own. This is due to advances in artificial intelligence and machine learning, which allow robots to learn from data and make predictions about the world around them. AI and ML empower robots to perceive their environment through sensors, interpret the collected data, and make informed decisions based on their understanding. This autonomy allows robots to adapt to changing conditions and perform tasks without constant human supervision.

  • Autonomous Self-Driving Cars: Self-driving cars are a prime example of robots with enhanced autonomy. Equipped with cameras, radar, and lidar sensors, these vehicles can navigate roads, detect obstacles, and make decisions to avoid collisions or follow traffic rules.
  • Robotic Assistants: Robotic assistants are revolutionizing healthcare by assisting in various medical settings. Surgical robots, for instance, offer minimally invasive procedures with greater precision and control, while robotic exoskeletons aid in rehabilitation and mobility enhancement.
  • Drones for Inspection and Delivery: Drones are becoming increasingly autonomous, performing tasks such as inspecting infrastructure, delivering goods, and even assisting in disaster relief. Their ability to navigate complex environments and make decisions without human intervention makes them valuable tools in various industries.

4. 3D printing of robotic hands with bones, ligaments, and tendons

Researchers at ETH Zurich have developed a novel 3D printing technique that enables the fabrication of robotic hands with intricate structures resembling human hands, complete with bones, ligaments, and tendons made from various polymers. This breakthrough holds immense potential for creating more lifelike and dexterous robotic hands with enhanced capabilities and applications.

The groundbreaking 3D printing method utilizes a sophisticated laser scanning technique that precisely controls the deposition of different polymers, forming bones, ligaments, and tendons with distinct properties. This multi-material approach allows for creating a hand with varying degrees of flexibility and stiffness, mimicking the functionality of the human hand.

5. Soft robots inspired by ancient marine organisms

Robotics researchers are increasingly drawing inspiration from nature to develop innovative solutions. One such area of focus is biomimetics, which involves emulating living organisms’ structures, mechanisms, and behaviors to create new technologies. One remarkable example of biomimetic soft robots is the work of researchers at MIT, who have drawn inspiration from an ancient marine organism called Pleurocystitida. These creatures, which existed nearly 450 million years ago, possessed a unique ability to move and adapt to their environment using a soft, muscular stem.

Inspired by Pleurocystitida’s remarkable capabilities, MIT researchers have developed soft robots that mimic the organism’s structure and movement. These robots are made of soft materials, such as silicone and elastomers, which allow them to deform and conform to their surroundings. This flexibility makes them well-suited for applications in challenging environments like disaster relief and search and rescue operations.
