Overview :

ReKep is a system for spatiotemporal constraint inference on robotic manipulation, encoding desired robotic behavior by representing manipulation tasks as constraints between the robot and its environment. Leveraging large visual models and vision-language models, ReKep generates keypoint-based constraints that can be optimized for multi-stage, field, dual-hand, and reactive behaviors without requiring specific task training or environmental modeling. Key advantages of ReKep include its versatility, lack of manual annotation, and the capability for real-time optimization by off-the-shelf solvers to produce robot actions.

Target Users :

The target audience for ReKep includes researchers and engineers in the fields of robotics, automation, and artificial intelligence. It is designed for professionals who need to develop robotic systems capable of understanding and executing complex manipulation tasks.
