The innovative Bi-Contact system, conceived by scientists and rooted in cutting-edge technology, enables robots to execute manual tasks with ease, thanks to real-time guidance from a digital assistant.

Researchers have published findings in IEEE Robotics and Automation Letters, detailing how artificial intelligence agents process their environment through a combination of tactile and proprioceptive cues, ultimately guiding robot behaviors to achieve precise sensing, subtle interaction, and effective object manipulation for task execution.

This breakthrough has the potential to transform industries like fruit selection, home services, and ultimately restore natural connection in artificial limbs.

“The lead writer from the School of Engineering defines the Bi-Contact system as enabling the rapid creation of AI brokers in a digital environment, capable of performing customised bi-manual tasks within mere hours.” And crucially, we will seamlessly integrate these digital brokers into the real-world environment without requiring any further training.

“The tactile bimanual agent excels at resolving tasks even under unexpected disruptions, deftly manipulating fragile items with precision.”

The seamless fusion of bilateral control and haptic cues is likely to unlock the ultimate potential for robots to achieve human-like dexterity in their interactions. While research into multi-arm settings lags behind that of single-arm configurations, this disparity can be attributed to the scarcity of suitable hardware and the added challenge of developing effective controllers for tasks featuring vast state-action spaces. With their expertise, the team successfully developed a cutting-edge, tactile dual-arm robotic system, leveraging the latest advancements in artificial intelligence and robotic tactile sensing technology.

Researchers created a digital simulation featuring two robotic arms equipped with tactile sensors. Developing reward features and a goal-update mechanism, they incentivize robotic brokers to master bimanual tasks, and create a real-world dual-arm robotic system where the trained agent can be directly applied.

Through a sophisticated technique known as Deep Reinforcement Learning (Deep-RL), the robot masters bimanual skills. This reinforcement learning system enables robots to learn through trial-and-error, leveraging a coaching paradigm similar to training a dog using rewards and penalties.

Robotic manipulation enables robots to learn through experimentation, attempting diverse behaviors to successfully complete designated tasks, such as lifting objects without compromising their integrity. As actions unfold with intended outcomes, success yields a tangible prize, whereas failure serves as a valuable lesson in avoiding similar missteps. As time passes, it develops a knack for discovering effective strategies to tackle problems by leveraging rewards and punishments. The AI agent operates without visual input, instead utilizing its proprioceptive abilities to perceive motion, position, and touch.

The team had successfully trained their twin-arm robotic system to carefully lift and handle even the most delicate items – like a solitary Pringles chip – with precision and safety.

The bi-contact system showcases a pioneering approach by offering reasonably priced software and hardware solutions that enable seamless analysis of bilateral behaviors in simulated environments, directly applicable to real-world scenarios. Our advanced tactile dual-arm robotic simulator enables in-depth examination of diverse tasks, as its open-source code fosters development of various downstream applications.

Here is the rewritten text:

The researchers at Yijiong have demonstrated that their innovative Bi-Contact system enables a tactile dual-arm robotic arm to be trained efficiently through simulation, ultimately allowing it to perform various manipulation tasks with precision and delicacy in real-world scenarios.

“And soon, we’ll create highly specialized AI agents that can seamlessly perform bilateral tasks within hours, tailored to specific client needs.”
