Re: Staying within volume with multiple extensions

Can I do this on either side of the robot as long as I retract on one side before extending on the other side? Does it make a difference if I have only one appendage that is capable of reaching out in either direction but not both, vs two appendages that I assure via software or a hardware linkage that only one will be deployed at a time?

It seems that the 'volume' of the robot for an undersized bot (at least in horizontal dimensions) is ambiguous, so how does it apply to rule G28 regarding affecting fuel outside the volume of the robot ?

I would assume the vertical volume of the bot extends above the bot, not below the wheels, but who is to say, especially while climbing?

hardware or software.
You would have to prove to inspectors that only one side can be deployed at a time.

As for the vertical volume, R03 does not specify being applicable in only one direction, so anything that extends below would be subject to it, and also

R23. BUMPERS must be located entirely within the BUMPER ZONE, which is the volume contained
between the floor and a virtual horizontal plane 7 in. (~17 cm) above the floor in reference to the
ROBOT standing normally on a flat floor. BUMPERS do not have to be parallel to the floor.
