Researchers at UC San Diego developed a new technology using WiFi sensors to help robots navigate indoors, even in poor lighting. The system accuracy rivals commercial camera and LiDAR sensors.
A new nanofiber-based biodegradable millirobot called Fibot can move in the intestines and release different drugs at anchored positions. Fibot's degradation capability is pH-responsive, allowing for controlled drug release.
Researchers have developed microrobot collectives that can move in various formations, reconfiguring their behavior quickly and robustly. The systems use a combination of magnetic forces, fluid dynamics, and computation to achieve coordinated patterns of motion.
A team of engineers and scientists has developed a proof-of-concept for a magnetic tentacle robot that can navigate the narrow tubes of the lung, enabling doctors to take tissue samples or deliver cancer therapy. The device measures just 2 millimeters in diameter and uses an autonomous magnetic guidance system to guide it into place.
Researchers at Imperial College London developed a bendy robotic arm that can twist and turn in all directions, allowing for customizable shapes. The team created an augmented reality system to enhance user-friendliness, enabling users to easily configure the robot using motion tracking cameras and smartglasses.
