Utility Robots

These are robots that Do specific tasks,

These are built by the 3D Robots and do special tasks from transport to other repetitive tasks

They could also be used for a host of other things outside as well.

Transportation bots
These are robots that move around raw materials so that other robots can use them.

They can be of any shape and size but they can also be omniwheel based and operate with 3D Robot.

Z-axis bots
This robot enables the 3D Robot to reach any height by having a moving platform that can go as high as needed. this robot can have a omniwheel base platform and a large z-axis platform that would allow the robot to reach very high. To move to different floors a elevator would be needed (or some other mechanism).
