The invention discloses an ostrich-like
robot walking mechanism. The mechanism comprises a
torso, a
thigh bone, a shin bone, an accessory metatarsal bone, a middle connecting rod and toes; a first camis fixed to the
torso, the
thigh bone is connected onto the
torso in a hinged mode, a
thigh bone push-pull and swinging mechanism is connected between the thigh bone and the torso, a second
cam is fixed to the thigh bone, one end of the shin bone and one end of the middle connecting rod are connected with the thigh bone in a hinged mode, and the other end of the shin bone and the other end of themiddle connecting rod are connected with the accessory metatarsal bone in a hinged mode; a shin bone push-pull and swinging mechanism is connected between the thigh bone and the shin bone; the firsttoe is connected with the
tail end of the accessory metatarsal bone in a hinged mode, the first
toe, the
second toe and the third
toe are connected in a hinged mode in sequence, and a
second toe push-pull and swinging mechanism is connected between the first
toe and the
second toe; a third toe push-pull and swinging mechanism is connected between the second toe and the third toe; a tension springis connected between the accessory metatarsal bone and the first toe, and a drawstring wound around the second
cam and the first
cam is connected between the torso and the third toe. According to themechanism, the walking and running gaits of an ostrich are fully imitated, and hitting the ground by legs, leg
recovery in the air,
leg extension in the air and landing of the toes can be achieved.
