Electromechanical Solenoids

[Uberpenguin564]

When considering methods to push the soccer ball, I thought of using a solenoid. Solenoids come in push or pull formats, and the idea is to use electrical energy to create linear motion (DC motors would create rotational motion). Current would flow through a coil of wire and create a magnetic field to push or pull a ferrous, usually iron, core. They're used in cars as relays, thermostatic control in refrigeration systems, etc. I thought this would be a relatively efficient method for kicking the ball without using pneumatics, and I want to know if this would be a viable option for the robot.

Thank you in advance for any input.

<R53> Items specifically PROHIBITED from use on the ROBOT include:
A. Electric motors and/or servos different from, or in addition to, those in the KOP, with the exception of those specifically permitted by Rule <R52>.
B. Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic solenoid valves – the latter are permitted, the former are not).

We too were thinking of using this as a method of kicking the balls, however <R53> states:

The bold text highlights the use of electric solenoids.

However, there is one way that might be viable, which is if the solenoid is built in house. I am in no way the GDC so you would have to post an official Q&A question, but based off of a ruling made for 272 in 2008, I know that the electromagnet they made on there robot was legal because it was a custom electronic piece made by them.
