What is the scale? I am asking because if it is 12 blocks is an inch you can add my robot made in mojang inventor.

Edit
Judging by the sack being 5 blocks I will assume your scale is 1 block is 1 inch so the entire field is 144 X 144 blocks and my robot is 216 X 216. lol I dont think it will fit in the alliance starting tile.
Each block is one inch so i cant add your robot, sorry. If i had made it any larger i would not have been able to render it all at the same time.
If you would make it in Tekkit, you could use micro-blocks and get better resolution in the same space
