Offhand, I can think of a few considerations:
- Looks like the side length would be ~37 in. for an equilateral triangle. This could make passing through a 36" door difficult if the bumpers are on (we have a hard time doing this with 28" robots with bumpers as is)
- You have ~23% less total volume available to you with the triangle configuration than the square configuration (with maxed out dimensions and an equilateral triangle).
These two items would dissuade me from pushing it in most cases, but in a game where space constraints are not an issue and you need wide pickups, I could see this configuration being useful.
