Are we allowed to use basic electronic components like diodes and resistors on the minibot?
From the rules, no.
<R92> The following items are the only permitted materials for use on the MINIBOTS:
A. TETRIX components that are not in violation of any other rules, (Tetrix components are listed in Approved Tetrix Parts at www.usfirst.org/frc/competitionmanual),
B. no more than two motors (PN W739083/W739023) and an unlimited number of Tetrix servos),
C. no more than one 12V rechargeable NiMH battery pack identical to those supplied in the FTC kit of parts (PN W739057) except the 20A fuse may be replaced with an equivalent type of lower amperage,
D. No more than one HiTechnic DC motor controllers,
E. No more than one NXT controller with the Bluetooth functionality disabled,
F. Polycarbonate,
G. Polycarbonate glue,
H. Raw welding rod, aluminum sheet, 90° angle, u-channel, tube, bar, that is not sold in pre-perforated or pre-punched form.
I. rivets,
J. non-metallic rope or cord,
K. wire nuts, solder, and crimps,
L. cable ties,
M. limit switches,
N. no more than two common household light switches,
O. electrical hookup wire,
P. non-slip pad,
Q. PVC or CPVC pipe and fittings,
R. PVC cement or cleaner,
S. Mechanical fasteners (e.g. screws, bolts, etc),
T. Loctite or similar thread-locking product,
U. Rubber bands,
V. Surgical tubing,
W. Electrical tape and shrink tubing,
X. PWM extension cables,
Y. Universal security clips to hold the PWM connectors together,
Z. Hook and loop fastener (may not be used as tape),
AA. Magnets,
BB. NXT compatible sensors and related connectors/cables,
CC. Grease, and
DD. Non-functional decorations.
[quote]Please note that the Rule only allows specific Tetrix components. While Tetrix components are a subset of FTC components, it is essential to realize that not all FTC parts are Tetrix parts. As such, not all FTC parts are permitted on the MINIBOT. Please be sure to vet your components against the above list before constructing your MINIBOT.
Use of glues/cements may not be allowed in the pits at tournaments based on site-specific rules.
Please note that the FTC Samantha module is not considered a TETRIX component and is not permitted on the MINIBOT.

Nadiv,
Do you have any applications for diodes and resistors in mind?
We did. If I’m thinking correctly, a shunt diode on the back end of the motors would make a great e-brake for the mini-bots.
But yea… just another idea that we cannot use.
