We are looking at using a suction cup on our robot this year. We still have the vacuum generator from last year and we are looking at using that for the suction. We were checking the rules for the pneumatic systems in the robot section of the user guide and it says, in section R87:
“Prior year FIRST Kit Of Parts solenoid valves, and pneumatic tubing may be used in addition to those provided in the 2008 Kit Of Parts. Their costs must be accounted for as explained in Section 8.3.3 Budget Constraints.”
It also says:
“For the purposes of the FIRST competition, a device that creates a vacuum is not considered to be a pneumatic device and is allowed. This includes, but is not limited to, venturi-type vacuum generators and off-the-shelf vacuum devices (as long as they are powered by provided or permitted motors).”
This says that we are clear to use it, but the next rule causes a problem.
“Additional 0.160” inch inside diameter pneumatic tubing functionally quivalent to that provided in the Kit Of Parts, with the pressure rating clearly factory-printed on the exterior of the tubing (note: alternate tubing colors are acceptable).”
We are wondering if we are allowed to use the small blue pneumatic tubing that is required for the valve. On one hand, it says we can, and on another, it says we can’t. Please help.
