We took it to the local PetsMart scale so its fairly accurate

Are those plates on top solid material? Do they need to be?
Yes solid 1/8 Aluminum, maybe not

Are the vertical support pieces solid? Will lighter extrusion work?
No they are 1x2 Aluminum extrusions, possibly switch to 1x1

What are the red things in the middle?
they are 8in concrete cardboard tubes used to hold the balls once they are captured

Is there any steel on the robot? Can you substitute aluminum of similar dimensions?

nope, all Aluminum, the only steel is the 2 3/8in rods on the shooter
