frame perimeter
does the frame perimeter have to be a complete rectangle? or could we make a U shaped robot?

Re: frame perimeter
You can make whatever shape robot you want. As long as it follows the bumper rules set out in 4.3.2 of the game manual.
Take note of the definition of FRAME PERIMETER Quote:

Re: frame perimeter
Be aware that MOST, but not all, 'U' shaped robots will violate the bumper rules.

Re: frame perimeter
The frame perimeter is the *convex* polygon that is formed by the external vertices of the robot. So, you can have a u-shaped robot, in so far as it meets the bumper requirements, but its frame perimeter will still be a that polygon formed by the external vertices.
There are rules in the glossary in section 1.6! Frame perimeter and Bumper Zone are two important examples... The blue box explanation for the Frame Perimeter has a good way of understanding it. |

Re: frame perimeter
By definition, a U shaped robot violates the bumper rules because it is concave.

Re: frame perimeter
Is it OK to reminisce about the years before bumpers?
![]() This year you can have an indentation, but it's limited in size and depth. (in the frame perimeter not the bumper itself) |

Re: frame perimeter
At which point having a U-shaped robot is pretty silly since you have that big bumper in the way.

The important item here is to understand how the FRAME PERIMETER interacts with the bumper rules. The FRAME PERIMETER is convex - there are no concave (or U shaped) openings - If you built a U shaped robot, the FRAME PERIMETER would include the outside edge of the U, and a straight line across the top of the U, turning it into a sideways D. That means that you need a bumper going straight across the top of the U, and it needs to be supported every 8 inches. |
