Physical AI is converging on two hard problems in 2026: giving robots a sense of touch and teaching them to handle soft, deformable materials reliably.
Three independent developments in April and May 2026 all point to the same gap: robots still lack the sensory and mechanical resolution to handle the physical world reliably.
DAIMON's fingertip sensor packs over 110,000 effective sensing units into a module the size of a fingertip, and their dataset is built to train models on that resolution at scale.
Researchers at Friedrich-Alexander-Universitat Erlangen-Nurnberg are scaling individual molecular machines into 3D structures that contract and expand under light, creating a new class of soft actuator.
Unlike rigid parts, deformable materials like fabric and flexible components change shape unpredictably during handling, requiring force control and real-time sensory feedback that current systems struggle to provide consistently.
Tactile sensing at scale, soft actuation research, and deformable material handling challenges all converge on the same root problem: physical AI systems lack the sensory and mechanical resolution to match human dexterity.
Watch tactile sensor deployment in real manufacturing environments, soft actuator research moving from lab to prototype, and which companies build the data infrastructure to train on high-resolution physical feedback.
According to IEEE Spectrum, Daimon-Infinity is described as the largest omni-modal robotic dataset for physical AI, released in April 2026. It combines high-resolution tactile sensing data with other modalities and covers tasks from home laundry folding to factory assembly line work.
As reported by Interesting Engineering, FAU researchers are scaling molecular machines into 3D structures that respond to light rather than electrical current. This approach could offer intrinsic mechanical compliance without gearboxes, potentially addressing backdrivability and force resolution trade-offs in conventional actuator designs.
According to The Robot Report, deformable materials like fabric change shape unpredictably during handling. Unlike rigid parts with fixed geometry, soft materials require continuous real-time force control and tactile feedback. Current physical AI systems struggle to maintain reliable grip and manipulation across these variable conditions.
That density approaches human-level tactile resolution. Most robot hands today operate with coarser feedback or none at all. Higher sensing resolution enables more precise force control algorithms, which directly affects a robot's ability to handle delicate or deformable objects without damaging them or dropping them.
According to IEEE Spectrum, DAIMON Robotics' Daimon-Infinity project includes collaborative support from Google DeepMind, Northwestern University, and the National University of Singapore, representing a combination of industry AI research and academic robotics expertise.
