Robotics engineers develop mechanical structures, electronic circuits, actuators, sensing systems, and AI-driven control algorithms for robots. They work on manipulation, mobility, autonomy, and human–robot interaction. Applications span manufacturing, logistics, healthcare robotics, defence systems, consumer robotics, space robotics, and service automation. They use CAD, embedded programming, ROS, simulation tools, and machine learning techniques. Robotics engineering is rapidly expanding as industries adopt automation, collaborative robots, and intelligent autonomous systems.
