On October 10, a team from Yale University published results in Nature: Machine Intelligence showcasing Tribar, a rolling robot that autonomously moved after falling 5.7 meters onto asphalt. This height marks the highest recorded fall for tensegrity robots.
Tribar's design, inspired by architect Buckminster Fuller, utilizes continuous tensile elements and discrete compressive elements to maintain stability. This allows it to absorb impact energy without a rigid shell, making it capable of withstanding high external loads without heavy armor.
The research team validated Tribar's performance across various terrains, including grass and ice, and demonstrated its ability to climb slopes and navigate complex paths. The robot's impact resistance and sensor capabilities suggest potential applications in environments where traditional robots struggle. No further timeline was disclosed at the time of publication.
Editor's Note
The development of Tribar highlights a significant advancement in robotic design, particularly in environments that pose extreme challenges. Its ability to absorb impacts rather than resist them could reshape how robots are deployed in disaster recovery and planetary exploration, reducing costs and risks associated with traditional landing systems.
