3-Sided "Y-Zipper"
MIT CSAIL 연구진이 40년 전 MIT 교수 William Freeman이 고안한 삼면 지퍼 'Y-zipper'를 현대 3D 프린팅 기술과 자동화 설계 도구를 활용해 부활시켰다. Y-zipper는 유연성과 강성을 빠르게 전환할 수 있어 텐트, 로봇, 의료용 착용기기 등 다양한 분야에서 신속한 조립과 변형이 가능하다. 연구진은 PLA와 TPU 소재의 내구성을 검증했으며, 향후 금속 소재 적용과 대형화도 계획 중이다. 이 기술은 재난 구조용 임시 구조물이나 우주 탐사 등 다양한 응용 가능성을 지닌다.

Cardiovascular disease is the leading cause of death worldwide, primarily damaging the heart’s atriums and ventricles.

Despite being the entryway to the heart, the right atrium has been overlooked — until MIT CSAIL & collaborators developed the most detailed map of its cell types and their functions across different disease states:

MIT’s New Robot Brushes Your Hair

Whether you care to admit it or not, hair is important to self-image, and not being able to deal with it yourself feels like a real loss of independence. To help people with limited mobility, researchers at MIT CSAIL have created a hair-brushing robot that combines a camera with force feedback and closed-loop control to adjust to any hair type from straight to curly on the fly. They achieved this by examining hair as double helices of soft fibers and developed a mathematical model to untangle them much like a human would -- by working from the bottom up.

It may look like a hairbrush strapped to a robot arm, but there's more to it than that. Before it ever starts brushing, the robot's camera takes a picture that gets cropped down to a rectangle of pure hair data. This image is converted to grayscale, and then the program analyzes the x/y image gradients. The straighter the hair, the more edges it has in the x-direction, whereas curly hair is more evenly distributed. Finally, the program computes the ratio of straightness to curliness, and uses this number to set the pain threshold.

The brush is equipped with sensors that measure the forces being exerted on the hair and scalp as it's being brushed, and compares this input to a baseline established by a human who used it to brush their own hair. We think it would be awesome if the robot could grasp the section of hair first so the person can't feel the pull against their scalp, and start by brushing out the ends before brushing from the scalp down, but we admit that would be asking a lot. Maybe they could get it to respond to exclamations like 'ow' and 'ouch'. Human trials are still in the works. For now, watch it gently brush out various wigs after the break.

Even though we have wavy hair that tangles quite easily, we would probably let this robot brush our hair. But this haircut robot? We're not that brave.
