A Bimanual Robot for Dynamic Manipulation AthenaZero just made the September cover of Science Robotics. {📌 Worth saving. I linked the full RAI Institute blog further down in the post if you want to dive deeper into AthenaZero’s design and control approach.} Researchers at the @rai_inst built a low-inertia bimanual robot to study one of the hardest problems in robotics: dynamic manipulation. And the first demos are pretty wild. AthenaZero can throw, catch and bat a baseball at speeds approaching human performance. • Throwing: up to 113 km/h • Catching: up to 66 km/h • Batting: around 50 km/h • Catching and batting over just 7.3 meters That short distance puts serious pressure on reaction times. But the interesting part isn't baseball. Most robot arms use high gear ratios that make them strong and precise, but also stiff and difficult to move compliantly during contact. AthenaZero takes a very different approach. Its arms use low gear ratios, as low as 5:1 in most joints, and have an effective mass at the wrist of only 3.97 kg. That's much closer to a human arm than a conventional collaborative robot. The result is a robot that can accelerate quickly, react to changing trajectories and absorb contact instead of simply fighting against it. The researchers demonstrated robot-to-robot and human-to-robot catching and batting, with the robot continuously adapting its motion to the incoming ball. Dynamic manipulation remains one of the hardest open problems in robotics. But systems like AthenaZero show what becomes possible when robots are designed for fast, physical interaction from the beginning. Blog: —— Weekly robotics and AI insights. Subscribe free:

Morgan Stanley with the rare ETF filing, this one for a slew of Eaton Vance state muni ETFs which are curr in CEF or MF form only. These should do well imo esp if fee is at Inst class or lower.

A gripper with two thumbs! 🐨 Handheld data collection is how a lot of manipulation datasets get built now. Someone picks up a gripper-shaped device, does the task by hand, and the recording becomes training data. Voila! 🤌🏼 The catch is that these devices are usually shaped to match whatever robot gripper already exists. The human ends up working around the robot's morphology, which costs both ergonomics and the quality of the demonstration being recorded. The @rai_inst team designed The Koala Gripper. It includes two devices with full parity: a capture device a person holds, and a robotic device that executes the learned policy. Anything you can do with one, the other reproduces. The shared feature set gets updated as the design iterates, so neither side quietly compromises the other. The morphology is where it gets interesting. Two independently controlled underactuated fingers are opposed by a single pivoting "dual thumb", which is where the koala name comes from. → Each finger is a 9-bar linkage with one actuated and one underactuated degree of freedom, with the spring sitting proximal to the phalanges to drive preshaping → Fingernails on the distal link for precise pinches, contoured pads for secure wrap grasps → The handheld trigger traces a natural fingertip arc instead of a straight line, lengthening the stroke and giving the operator better mechanical advantage → On the robot side, a frameless motor with an integrated high-pitch ballscrew keeps reflected inertia low, so the fingers stay backdrivable at an effective mass of tens of grams The dual thumb is what buys tool stabilising, singulating one object out of a pile, and tabletop pinches.

Structural Conclusion On June 13, 2026, the global civilizational system's Resilience Ratio remains below the 0.70警戒线 for the fourth consecutive day. What is most worth recording today is not war – but the first time in human civilization that private wealth approaches the GDP of a中等发达国家. When a single entrepreneur owns a satellite network, rocket system, AI platform, energy network, financial capital, and global data流入口, civilization is entering a new organizational form: Transitioning from nation-state-led civilization to platform-infrastructure-led civilization. If the core question of the 20th century was "How to constrain state power?", then the core question of the latter half of the 21st century may well become "How to govern super-platform power."
