Basic Robot Layout

[KenWittlief]

Generally speaking the primary consideration for physical layout is center of gravity and stability. You want the robot to be as stable as possible, which means:

1. having the most massive components twords the center and the bottom (battery, motors drivetrain...) and

2. having your wheel base as wide as your design limitations allow.

The electrical control system is usually in one location with power and control signals running where they need to go. Some people put the motor controllers right next to the motors, and others put them all in one spot and run the motor wires out from there.

The actuators (arms, grippers...) are designed according to the functions they are required to perform, but the same general rule applies: try to keep the heavy parts low and towards the center of the robot.
