🔑 增強重點摘要
- •The fourth-generation Stretch robot, available for $29,950, features a 'sensor-rich' architecture, including two hemispherical 3D lidars, three high-resolution cameras, and six laser line sensors, to enhance safety and perception in dynamic environments.
- •Stretch 4's mobile manipulation capabilities have been significantly upgraded, with its arm, lift, and base operating at twice the speed of its predecessor, Stretch 3, and a 10% increase in total reach.
- •The robot is designed with an emphasis on safe human-robot interaction, prioritizing a lightweight, compact, and low-potential-energy design over complex humanoid forms, making it suitable for close collaboration with people in homes and workplaces.
- •Hello Robot has integrated an NVIDIA Jetson Orin NX into Stretch 4, providing robust compute power for running advanced AI models and supporting the development of Physical AI applications.
- •The Stretch platform has been piloted to support individuals with severe mobility impairments, demonstrating its practical utility in tasks such as fetching drinks, closing blinds, and assisting with feeding, controllable via a mobile phone app.
🛠️ 技術深入
