Beijing E-Town Half Marathon Kicks Off: Traffic Police Robot Makes Command Debut, Multiple Humanoid Robots Compete on the Same Track

Brief:

On April 19, Beijing’s first traffic police robot made its official debut on the course of the 2026 Beijing E-Town Half Marathon, directing traffic. It can already perform functions such as traffic gesture commands and travel guidance, and will later be piloted for duty at intersections.
Unitree Robotics’ H1 robot, the 2023 revised version, took part in the Beijing Humanoid Robot Marathon qualifying race. It autonomously completed a 1.9-kilometer course with multiple turns in 4 minutes and 13 seconds. Converted proportionally, the result would break the human 1,500-meter world record.
A “short-legged robot” holding a baby bottle appeared at the race and sparked online discussion. The robot is Mini Pi Plus, produced by High Torque Robotics. It uses a modular design and supports high-precision motion control. 🍼
A netizen-made “Bean Foot” robot also appeared at the marathon. Inspired by a Douyin creator, it uses High Torque Robotics’ Xiao Pai body with a virtual character headpiece, giving it a distinctive look. 🤖

谷歌开源40亿参数医疗AI模型MedGemma 1.5，全面支持3D影像分析

简报：

谷歌近日开源医疗AI模型MedGemma 1.5，突破传统2D图像局限，原生支持CT和MRI三维扫描数据分析及病理学全视野数字切片分析。
在保持40亿参数量不变的前提下，新版本较上一代在3D MRI病情分类准确率提升11%，胸部X光解剖定位交并比增加35%，电子病历问答准确率提升22%。
团队为模型注入了大量医学图文配对数据并引入专家模型进行知识蒸馏，但该模型目前仍定位为供开发者微调的基础资源，非开箱即用的临床决策工具。

Google Open-Sources 4-Billion-Parameter Medical AI Model MedGemma 1.5, with Full Support for 3D Imaging Analysis 🩺

Brief:

Google has recently open-sourced the medical AI model MedGemma 1.5, breaking beyond the limitations of traditional 2D images with native support for analyzing 3D CT and MRI scan data, as well as whole-slide digital pathology images.
While maintaining the same 4 billion parameter size, the new version improves upon the previous generation with an 11% increase in accuracy for 3D MRI disease classification, a 35% boost in intersection-over-union for chest X-ray anatomical localization, and a 22% gain in electronic health record question-answering accuracy.
The team infused the model with a large volume of paired medical image-text data and introduced expert models for knowledge distillation. However, the model is still positioned as a foundational resource for developers to fine-tune, rather than an out-of-the-box clinical decision-making tool. 🔬📊
