A humanoid robot is a robot whose body is modeled on the human form — typically with a torso, head, two arms and two legs. The purpose of this design is to operate in environments built for people and to use human tools, controls and pathways without structural modification.
Humanoid robotics is a demanding research field requiring rich sensorimotor capabilities: bipedal balancing and walking, grasping and manipulating with hands (end effectors), and perceiving the environment through cameras and sensors such as LiDAR. Many degrees of freedom and precisely controlled actuators make control especially complex.
Applications range from research and service robotics to manufacturing and logistics, where humanoid robots are intended to take on repetitive or dangerous tasks. Well-known examples include Honda's ASIMO as well as newer systems such as Boston Dynamics' Atlas or Tesla Optimus. However, fully autonomous, general-purpose humanoids remain an open challenge.
