EE192: Mechatronics Design Lab
Final Race
The races will be carried out using NATCAR rules for timing (best run in 5 minutes, with timeout and second try with max of 2 minutes).
Round 1
Round 1 will be scored out of 10 points as follows:
6 points | Moves under own power |
6.5 points | Makes first turn |
7 points | Completes 1/2 of the track in < 5 minutes |
8 points | Completes whole track in < 5 minutes
about 0.3 m/s |
9 points | Completes whole track in 2 minutes or less
about 0.8 m/s |
>9 points | For cars which are fast and/or well-stabilized
|
The final point, once you score 9 points based on time, will be awarded on a deductions system as follows, floored at zero:
-0.3 points | Twitchy steering |
-0.3 points | Goes wide on curves |
-0.3 points | Oscillatory step response |
-0.3 points | Over 60 sec
about 1.6 m/s |
-0.5 points | Hits cone(s)
|
Round 2
Time is = min(CW) + min(CCW). Total length is about 320 feet.
Assumed coefficent of friction 0.5, min radius 0.4 m.
Round 2 will be scored out of 20 points as follows:
12 points | Moves under own power |
13 points | Makes first turn |
15 points | Completes 1/2 of the track in < 5 minutes |
16 points | Completes whole track in < 5 minutes
about 0.3 m/s |
18 points | Completes whole track in 85 sec or less
about 1.4 m/s |
>18 points | For cars which are fast and/or well-stabilized
|
The final two points, once you score 18 points based on time, will be awarded on a deductions system as follows, floored at zero:
-0.5 points | Twitchy steering |
-0.5 points | Goes wide on curves |
-0.5 points | Oscillatory step response |
-1 point | Over 60 sec
slower than 1.6 m/s |
-1 point | Loose hardware
including car scraping on track |
-1 point | Hits cone(s)
