1X Robotics 将电机移至前臂，通过肌腱驱动穿过手腕，使 Neo 机器人的手更轻、手指运动与力更强。手部拥有 22 个主动自由度（手指与手掌）及 3 个手腕自由度，总计 25 自由度。触觉传感器可读取抓取过程中的压力、接触位置和侧滑，使 Neo 能在硬币、葡萄或工具掉落前调整抓握。手部达 IP68 防护等级，可用于水槽、食物和潮湿表面。不过 Neo 仍非完全自主，困难任务中需依赖远程人工引导的 Expert Mode。引用称该肌腱驱动手在灵巧度、力量、速度和可靠性上接近或超越人类水平。
Robotics is limited by hand, but it looks like 1X just pushed past that bottleneck.
They moved the motors into the forearm, then routed tendon drives through the wrist. That keeps the hand lighter while giving each finger more useful motion and force.
The hand has 22 powered freedoms across fingers and palm, plus 3 at the wrist.
Its tactile sensors read pressure, contact location, and sideways slip during a grasp.
This means Neo can adjust before a coin, grape, or tool falls away.
The IP68 rating also makes the hand usable around sinks, food, and wet surfaces. The catch is that Neo is not purely autonomous for every chore yet.
1X still uses Expert Mode, where a remote human can guide difficult tasks.
A human hand uses the same broad trick, with muscles pulling tendons across joints.
1X is applying that idea to humanoid robotics, where compact hands must handle real objects.
Introducing NEO’s 25 Degrees of Freedom, tendon-driven hands — nearing or surpassing human-level dexterity, strength, speed, and reliability. For seventy years, robotics worked around the hand problem. The humanoid bet is the reverse: it lives or dies at the fingertips.在 X 查看被引用的帖子
