FRC 2859's Kicker Prototype 2
http://www.youtube.com/watch?v=Lf66SvvE7ks
Now it's not going to be as extreme as it is in the video. It's being toned downed for the actual robot downsized. The mech1 team just wanted to settle a bet with a mentor. They won cookies. ![]() |

Boom, nice...........
That's a bunch of spinning metal under a lot of stress for you guys to not be wearing safety glasses. |

Re: FRC 2859's Kicker Prototype 2
That was pretty sick spin you put on that ball. That was as close to a real human kick I've seen, yet.

Sweet kicker, how do you plan on cocking it back? |

Re: FRC 2859's Kicker Prototype 2
Very impressive... if you can control it and get it repeatable.
Also, as an inspector for the Denver Regional, I would ask you to come prepared for many questions about that device. As I watch I could easily see a long discussion involving the safety inspector about all conditions of failure on that thing. |

It can be adjusted, depending on much it's ratched back, so the amount of energy can be varied. And yes, they are aware of it, one of the mentors was betting them that they couldn't make it go 60 ft. because prototype 1 was only able to do 30 ft., thus prototype 2. He lost and bought the Mech1 team cookies. Quote:
At least they tested it outside, at the beginning the kept testing the kicker in the hallway and their two toed metal foot made the ball go vertical and hit the ceiling instead, fortunately no damage to the tile and there was no light in the way. Quote:

It's repeatable, the results were consistent, the question is mounting their motor parts, currently they're making prototype 2A(motor mount & shorter leg).

Re: FRC 2859's Kicker Prototype 2
Using humans as sandbags does not seem like a thoughtful undertaking when such a forceful arm is swinging within inches of the "sandbags". Especially when there is nothing keeping humans from swaying into the path of the kicker. I think one of the attached photos shows a gouged and bloodied forearm.
Was that due to a human playing the role of a sandbag? Any fast moving pendulum should typically have safety cages to help prevent accidents. Think safety first, especially when adolescents and cookie rewards are involved. Maybe cookie bets on beating power/distance records are counterproductive to rational safety assessments. Just imagine if the were no safety issues and we could all just enjoy the demonstration of engineering acheivement... There is always next time. |

* safety glasses * safety cages * filing sharp cut metal as soon as its cut before of letting team members lean on it * trying to reducing the number of people within inches of 60 FPS metal objects are suggestions of smothering- then you and I have totally different ideas of what smothering is. I am truly glad no students were hurt- I would think the goal would be for all team members to be unbloodied and gouge-free, not just the students. Maybe liability lawyers in Colorado are totally different than lawyers on the East Coast. I would appreciate if let us know the outcome of your next conversation with your legal department and whether you would volunteer to show them the videos and pictures that were shown here and these posting and your responses. After you show them the video and pictures, would you be willing to ask the legal department if they would consider ANY or ALL of the suggestions offered in this thread as amounting to be "so smothering all the time"? |

You're suggestions have been noted and I've shared it with the other mentors and students,although what they think and feel about it is up to them. |
