Current Robotics has released CurrentWorld-0, an interactive world simulator that integrates cross-embodiment, multi-view, and force-tactile prediction for robot evaluation. The team, previously cited by Physical Intelligence's π0 paper for their TinyVLA work, aims to provide a unified world for robots to rehearse before entering the real world.

Robots come in many shapes, but they face only one world. Current Robotics releases interactive world simulator CurrentWorld-0, unifying cross-embodiment, multi-view, and force-tactile prediction into a single system for the first time, letting robots rehearse in a world that won't correct their mistakes before entering the real one.
A natural starting point for robot world models is video generation models. After large-scale pretraining, these models have learned many visual and motion regularities, such as objects not vanishing when occluded and motion being temporally continuous. But the abundance of successful examples in robot training data has made models familiar with trajectories like 'reach-grasp-lift.' When an untrained policy reaches off-target, the video prior sometimes fills in the subsequent results to lean toward 'success.'
The result: the robotic arm hasn't actually grasped securely, yet the generated image shows the object following the hand. Real execution has failed, but the world model's future still completes the task smoothly. In robot evaluation, such 'correction' directly distorts results. Current Robotics previously studied exactly this in dWorldEval: the action controllability of world models. When the action changes, the subsequent world must also change. If the robot veers slightly left, the object cannot continue along its original trajectory; if the action has failed, the model cannot patch the outcome back to success.

Descriptions of product features and team background are based on that report and have not been independently verified. The claim that 'π0 cites TinyVLA and ScaleDP' is as stated in the report, without direct evidence provided.
