Re: Electromagnets - McMaster

Be very careful on how to use your electromagnet.

Quote:
<R46> Items specifically PROHIBITED from use on the ROBOT include:
A. Electric motors and/or servos different from, or in addition to, those listed in the 2011 KOP Checklist, with the exception of those specifically permitted by Rule <R45>.
Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic solenoid valves – the latter are permitted, the former are not).
In the past*, we've seen the GDC rule that an electromagnet could be considered a solenoid and thus be prohibited depending on its use. Specifically, if you used the electromagnet to create any motion (for example, turn it on and it pulls a lever from one location to another), it would be illegal. An electromagnet that was utilized specifically for the purposes of attachment would be permitted (using the same example, a motor moves the lever into the desired position, then the electromagnet activates to hold it in position).


I would highly recommend asking the GDC about electromagnet applications with regards to the above rule.


*Please note that past year GDC rulings don't necessarily apply to this year... but they can give a very good indication as to how the GDC will rule with regards to certain applications and similar rules.
