Abstract: A leg structure includes: a pair of first-stage leg servos connected to the waist structure, each of the first-stage leg servos including a first output shaft; second-stage leg servos corresponding to and arranged opposite to the first-stage leg servos, the second-stage leg servos including second output shafts perpendicular to the first output shaft; a pair of connecting assemblies each used for mounting one of the first-stage leg servos and one of the second-stage leg servos, the connecting assemblies each including a connecting member for mounting one end of the first output shaft and one end of the second output shaft, a first end cover fixed to the connecting member and used for mounting the other end of the first output shaft, and a second end cover fixed to the connecting member and used for mounting the other end of the second output shaft.

Abstract: A foot structure for contacting the ground and connecting to a leg structure of a humanoid robot, includes: a foot assembly for contacting the ground; a first servo mounted on the foot assembly and including a first output shaft; a connecting assembly rotatably connected to the foot assembly and to constitute an ankle portion; and a second servo mounted on the connecting assembly and connected with the leg structure, the second servo including a second output shaft perpendicular to the first output shaft; the connecting assembly being arranged perpendicularly to the foot assembly and including a first connecting structure used to mount the first output shaft and rotatably connected to the foot assembly, and a second connecting structure connected to the first connecting structure and used to mount the second output shaft.

Abstract: A toy assembling apparatus is disclosed. The toy assembling apparatus includes at least one connector, and each connector having at least one of a first connecting portion and a second connecting portion. The first connecting portion includes a connection plate and a connection pillar disposed on the connection plate. The second connecting portion includes a left side board, a right side board, a back side board, a bottom board, and a top board, which jointly form a containing slot for inserting the first connecting portion. The containing slot includes a plate slot for containing the connection plate and a pillar slot for containing the connection pillar. Limit grooves or limit protrudes are formed on the connection pillar. The pillar slot has protrudes or grooves formed thereon correspondingly. The limit grooves match the limit protrudes, such that the first connecting portion matches the second connecting portion of another connector tightly.
