Is having a microcontroller for each specific task a good idea? A controller for movement, one for arm, one for ect. Or, should I use one microcontroller for all controlls?

Which chip is better? BASIC 2p BASIC 2sx BASIC 2e BASIC 2i BASIC 2

Hello, my name is Will Clark. I am a young hobbyist trying to build a robot. I am not sure of the materials required. I plan to use a starter engine I found in an old car. I want to build a 4-wheeled robot with a plexiglass shell. The major problem i have is with the speed controll and the battery hookups. Any help would be greatly appreciated. Thank you.
