Re: pic: Team 1504 minibot final
How does this latch onto the tower? It appears as if the wheel shafts/positions are fixed...

Ah. It appears to be magnet based. It kind of resembles one of our prototypes.

Re: pic: Team 1504 minibot final
What kind of switch is that little red/blue one on the left end? Is that a Tetrix switch or a common household light switch?

How big are the magnets and where did you get them?

Re: pic: Team 1504 minibot final
Not sure if he used the ones I got from Harbor Freight. There is a section around the watch tools in Harbor Freight that has ceramic magnets and 100-250# magnets. They may have used these or purchased neodymium mags somewhere else. I have a note into the mentor for he minibot to come over here and give us an answer.

I found some magnets that we are going to try from McMaster-Carr.
Ultra-High-Pull Neodymium Ring Magnet 1" OD, 1/2" ID, 1/2" Thick, 21.4 Pull lbs. Part # 3360K79My thought is to add a small bearing in the center and mount it so that it allows the minibot to travel in the vertical plane without falling away from the pole. |
