Re: pic: FRC488 2007 Robot
Have you considered adding "ramps" to the outside edges of the platform, allowing teams to approach and climb then from angles (also allowing wider robots a chance to get on)?

Re: pic: FRC488 2007 Robot
I'm very interested in your lift mechanisms there under the ramps. What do you use to power them? Looks very intriguing though, one of the more creative designs I have seen thus far. Nice looking model.

Re: pic: FRC488 2007 Robot
The lifts are each comprised of two four bar linkages. Each linkage is driven by a 125 lbf. gas spring that is held closed by a mechanism that's not shown -- it, too, was a fatality of the recent redesign. The gas springs allow the lifting to occur without the need for power or stored air -- so we feel that it should be a reliable mechanism for lifting robots at the last possible moment. Also, we like that the gas springs of the same extension are available in different values of output force, so if we find that 250 lbs. per side is too much or too little force, we can change it quickly and easily.

Re: pic: FRC488 2007 Robot
I like! My team was theorizing of something like that. Only second complete Inventor design/photo I've seen of a robot with no ringer capacity (as far as I can tell). Although, it appears to me like you've got a good, steady lifting design that (correct me if I'm wrong) can lift to 12", giving you a guaranteed 60 points, which is very valuable, IMHO. Very nice overall.
Can you shed some light onto what the two small protrusions at the bottom (picture-wise, top right) of the robot are? They look almost like tower supports, but in the bottom right head-on view, there's no tower. Can you describe what they are? It's interesting to me that for a (I assume) defensive robot you chose the omnis with powered middle wheels. From what I've heard, you could get turned around your axis pretty easily. Did you choose to put two motors to each side to counteract it? Nice design overall. |

Re: pic: FRC488 2007 Robot
Looks sweet, Madison!
I was wondering, what would happen if only one robot could climb up onto your ramps (say, your other partner was broken/disabled during a match)? Do you have the stability to lift one robot while the other side is empty, or is that an impossibility? |

Re: pic: FRC488 2007 Robot
OK, I see the outline of the linkage under the ramps in the one view. Groovy.
