This is a huge lion animatronic model. It is well known that it is very difficult to make a big cat sculpture. The modeling details of the facial muscles of the sculpted lion model require a lot of time to adjust. The overall animatronic animal model presents a standing and looking back posture. In the motion programming design, we have made head movements, as well as eye and tail movements within a reasonable budget. When the infrared sensor is triggered, the animatronic lion starts to move, as if it roars on its territory declares sovereignty.
