IA e robótica
Definição
AI in robotics covers perception (vision, touch), planning (motion, task), and control (actuation). Reinforcement learning and imitation learning train policies from data; sim-to-real transfer is a key challenge.
A percepção frequentemente usa visão computacional e às vezes modelos multimodais. Políticas de controle são treinadas em simulação (DRL) or from human demonstrations; deploying to real hardware requires dealing with dynamics mismatch (sim-to-real), safety, and latency.
Como funciona
Sensores (câmeras, força/torque, propriocepção) alimentam modelos de percepção que estimam estado (por ex. poses de objetos, layout da cena). Planejadorrs (classical or learned) produce trajectories or high-level actions (por ex. “pick block A”). Controllers (por ex. PID, learned policy) execute low-level commands (joint torques, velocities) to track the plan. End-to-end learning maps raw sensor input to actions in one network; modular pipelines separate perception, planning, and control for interpretability and reuse. Training is often in simulation (DRL); sim-to-real (domain randomization, system identification) and safety constraints are critical for deployment.
Casos de uso
AI robotics applies when perception, planning, or control are learned from data (manipulation, navigation, sim-to-real).
- Manipulation and grasping (por ex. pick-and-place, assembly)
- Navigation and autonomous driving
- Sim-to-real and imitation learning for policy training
