Robot intentionally tipping over

Rule G25 states:

A ROBOT may not attempt to stop or impede the flow of the MATCH in any of the following ways:
A. intentionally tipping over
B. coordinating a blockade of the FIELD with ALLIANCE members
C. blocking GOAL(S) while in contact with its own BATTER using anything outside its FRAME PERIMETER

So could you intentionally tip the robot over without trying to impede the flow of the match?

Re: Robot intentionally tipping over

Why would you want to tip over? If you mean tipping over to block a goal or a defense, I would consider those to be impeding the flow of the match.

I was thinking about a way for a tall but thin robot to go under the low bar. I was just curious about this method.

Re: Robot intentionally tipping over

I would THINK you would then have to then look at the 120 inch frame rule because there have been instances (last year I believe) where it was then considered to be changing configuration and then the height would be considered the "frame perimeter."

Re: Robot intentionally tipping over

Notice "stop or impede the flow of the MATCH". If it is intentional, and part of your strategy, then the judges may consider it ok. It may vary judge to judge, however. After tipping over, it may be difficult to get back up, which may limit it's functionality. You may want to look into G18, which limits the robot from extending 15in past its perimeter.

Re: Robot intentionally tipping over

I was thinking the same thing. Using this method, you could theoretically get a robot taller than 1' 4" through under the low bar. I was thinking an "L" design with wheels on both sides. I could see perimeter stuff causing an issue though.

This has little to do with the rule, but please note the difference between judges and referees. It's an important distinction.

Re: Robot intentionally tipping over

You would also probably need bumpers running the height of your robot, so it would still meet the bumper rules when tipped over.

Teams like 1114 and 1241 had transportation configurations that were not the same orientation on the field, yet were not penalized for size violations, because they could still fit into the box. However, sizing rules were very different last year. In 2013 and 2014, where the same frame perimeter rule was imposed, I don't recall there ever being an instance of the issue you describe, although there probably wasn't an instance where that issue could have occurred.

Re: Robot intentionally tipping over

I believe the rule that may stop this is the "can't extend 15 inches past frame perimeter" rule.

You cannot change perimeter mid match so if you went from a skinny drive train to a long one you would exceed the 15 inch reach.

Thats how I would see it anyways. I may be wrong.

G7 When placed on the FIELD for a MATCH, each ROBOT must be:
D. confined to its STARTING CONFIGURATION,

Quote:

STARTING CONFIGURATION
the physical configuration and orientation of the ROBOT when the MATCH is started.This is the state of the ROBOT immediately before being Enabled by the FieldManagement System, before the ROBOT takes any actions, deploys any mechanisms,or moves away from the starting location. This configuration is static, and does not change during a single MATCH (although it may change from MATCH to MATCH). In the STARTING CONFIGURATION, no part of the ROBOT may extend outside the vertical projection of the FRAME PERIMETER, with the exception of minor protrusions such as bolt heads, fastener ends, rivets, etc.

Quote:

R3 The ROBOT must satisfy the following size constraints:
A. total length of the FRAME PERIMETER sides must not exceed 120 in. (see Figure 4-1 for examples),
B. must not extend greater than 15 in. beyond the FRAME PERIMETER (see Figure 4-2 for examples) (see G18), and
C. ROBOT STARTING CONFIGURATION height must not exceed 54 in. (note that ROBOT height may exceed this limit in-MATCH as allowed by G17).

Quote:

R22 BUMPERS must be located entirely within the BUMPER ZONE, which is the volume contained between two virtual horizontal planes, 4 in. above the floor and 12 in. above the floor, in reference to the ROBOT standing normally on a flat floor. BUMPERS do not have to be parallel to the floor.

In my opinion the combination of these rules prevents any "flop bots".

I find it hard to believe that a referee will allow a robot to have sideways bumpers in a match. I believe bumpers were intended to protect the world from the robot and the robot from the world. Having the bumpers sideways like that would be unsafe imo. You may not even pass inspection if you intend to do this as part of the robot design.
But if you have a way to move your bumpers down... that looks so complicated, it's probably not worth it though imo.
