Minibot Tetrix Modification?

[Bmarquez]

while this thread might not be the best place for this question,

ive combed through the minibot rules back and forth and up and down, and i cant find a direct answer of yes or no.

Does the minibot frame itself have to be made with tetrix parts?
because i'd much sooner make it out of an ultralight aluminum and drill/mount the parts myself then deal with the shoddy tetrix parts any longer then i already have today in class.

What is allowed for use by <R92>?

If it's on the allowed list, then it is allowed. If it is not on the allowed list, then it is not allowed.

Per the rules, you could make the MINIBOT out of nothing but cable ties and wire nuts.

looks like me and my power drill are going to get very friendly tomorrow.... making a working frame out of sheet metal should be pretty quick to bolt together, and grind/polish/finish. According to the materials in part R92, sheet metal is allowed so i guess it was a silly question x.x.

i figure the extra zerospace allowed in a fully sheet metaled part will also keep the weight down and give me freedom in mounting/angling the pieces where i want them.

Thank you for clearing that up!

can i melt down the tetrix aluminum in a forge and pour sand castings to use on my pole-bot?

[aldaeron]

The following items are very vague with regard to modification (I expect more clarification as the season goes on but am curious to see your thoughts):

F. Polycarbonate
H. Aluminum sheet, 90° angle, u-channel, tube, bar
Q. PVC or CPVC pipe

In particular I am interested in manufacturing my own wheel with a "U" cross section (think of a pulley) where the radius of the "U" in the wheel is 1.74 inches/2 = 0.87". This would keep the minibot on the pole very nicely.

Can I machine or form this type of wheel out of polycarbonate stock?

Can I take a piece of U channel aluminum and carefully heat and bend it backwards using a steel guide to create this type of wheel?

Can I get four PVC 90 degree elbows, cut them in half along the radial center and glue them together to create this type of wheel?

Also - can the aluminum pieces be welded?

Specifically sheet aluminum.

Don't forget the battery.

And the motor(s), assuming of course that you want to go upwards.

And every thing else you need to actually play the end game ....

The allowed lists is just that. You are allowed to use anything on the list. Per Update #1 you must use one battery and one or two motors.
Tytus, I think the air in your suit is getting a little thin, open the door and let some fresh air in.
