6.2 Playing Field

Robot part on the Spider Foot

Posted by FRC619 at 01/12/2007 10:58:51 am
Can a robot part lie on top of or touch the Spider Foot/Stinger, but not be held? There is no mention of the foot or the top of the leg in the below answer.

The Spider Legs are considered part of the field structure, and are covered under Rule <G33>. The Spider Legs may be pushed to one side, from the front, or from the bottom, to stabilize them during the process of hanging a game piece. However, they may not be grasped, held, or
severely restrained without violating this rule.

The Spider Foot and Stinger are considered sub-parts of the Spider Leg. As such, all rules and rulings regarding the Spider Leg also apply to the Spider Foot and Stinger.

Our arm pushes down on the top of the spider foot while pulling back. We'll be careful when it comes to game play. Check out this video: http://youtube.com/watch?v=2o2etWefu...elated&search= for a different view.

Thank you for your comment, you really got us thinking.

Looks kewl.

You may want to keep this rule in mind though:
<R03> Protrusions from the ROBOT must not pose hazards to team members or event staff. If, in the judgment of the inspectors or referees, a device on the ROBOT poses a hazard (particularly puncture or impalement hazards), the team will be required to remedy the situation before the ROBOT will be allowed to play. If the ROBOT includes protrusions that form the “leading edge” of the ROBOT as it drives, and are less than one square inch in
surface area, it will invite detailed inspection. For example, forklifts, lifting arms, grapplers. etc. may be carefully inspected for these hazards.

We haven't popped any tubes so far and the arm passed inspection at our local scrimmage event.

We drive with the arm in the upright position for a better center of gravity. Thank you for pointing out this rule, we do not want to impale anyone or damage any robots.

The bent barstock is less than 1". Just in case, we're going to prepare bigger pieces for our first regional. Thank you again for finding the rule.

0.005" lexan film is actually great for this application, and is available from McMaster for a very reasonable price (less than $4)

Thank you for the advice. I'm going to have my team order it ASAP.
