My own human-shaped robot
It has 2 color variants - orange and blue. It is fully rigged with inverse kinematics, unimportant bones are hidden. It is modeled in real size and nicely orderly in collections so you can easily append them into your own Blender projects in just 1 click via collections. It is ready-to-use.
The textures are packed right into the .blend file so there shouldn´t be any problem with them. However, if there are any problems, write them down in comments, I will try to fix them :)
