📰 A company's new robot can change from four wheel drive to bipedal in seconds A company called Swiss-Mile has created an innovative robot that combines legs and wheels to create, what they hope, will be the most versatile last-mile delivery robot on the…
Zürich-based Swiss-Mile has enhanced the ANYmal quadruped robot with powered wheels for speed and efficiency, enabling it to handle curbs and stairs. The robot has been taught to stand up, facilitating more versatile movement and manipulation using its wheel-hand-leg-arms. Researchers at ETH Zurich's Robotic Systems Lab employed curiosity-driven learning, a form of reinforcement learning, to train the robot in tasks like opening doors and placing packages into boxes.
The robot's curiosity about specific elements, such as the door handle or package motion, helps it explore and innovate solutions independently. The use of sparse rewards in training results in diverse and reliable behaviors, allowing the robot to recover from real-world mistakes. While relying on visual code-based systems like AprilTags, Swiss-Mile aims to further develop the robot's capabilities, indicating potential practical applications for the ANYmal.

Tesla has unveiled the Optimus Gen 2 humanoid robot, showcasing improved humanlike dexterity and mobility. The robot features 11 degrees of freedom in its hands with tactile sensors in each finger, a 2-DoF neck, in-house-designed actuators and sensors, and integrated electronics. The enhancements include a 30% increase in walking speed, force/torque sensing, articulated toe sections in its feet, and a 10 kg weight reduction for improved energy efficiency, cost, and safety.
The company plans to initially deploy the robot in its automotive and battery factories. However, amidst the positive news, Tesla is also recalling over 2 million vehicles due to concerns surrounding its Autopilot system. The National Highway Traffic Safety Administration (NHTSA) is investigating safety issues related to Autopilot, and critics argue that Tesla didn't adequately communicate the risks.
Despite the recall, Tesla CEO Elon Musk has released an impressive video of the Gen 2 Optimus robot, emphasizing its capabilities and addressing skepticism. Musk believes the Optimus business could eventually surpass the value of Tesla's car business and full self-driving technology.

Andrej Karpathy, from OpenAI, developed Baby Llama as a weekend project to demonstrate the possibility of running the Llama 2 model on edge devices. The project, inspired by Georgi Gerganov's llama.cpp, involves training the Llama 2 model using PyTorch and then saving the weights in a binary file. Karpathy created a compact C file ('run.c') for loading and running the model with single-precision calculations, ensuring a low-memory footprint and independence from external libraries.
The model runs efficiently even on a single M1 laptop without GPUs, with performance enhancements achieved through various compilation flags for code optimization. A Twitter user successfully demonstrated Baby Llama running on a Samsung Galaxy Watch 4.
Karpathy's repository provides the pre-trained model and code, allowing anyone to experiment with Baby Llama on their devices. It's important to note that this project is experimental and not meant for production use, aiming to showcase the viability of running advanced models on low-powered devices with C, a language typically not associated with machine learning due to its GPU incompatibility.
