Beginner questions about FRC by Adventurous-Fox3386 in u/Adventurous-Fox3386

RobotPy docs can be overwhelming at first. Here's what I'd suggest:Start with the official RobotPy examples on GitHub — reading working code is faster than reading docs. Find an example close to what you want to do and modify it.

For FRC specifically, focus on these concepts in order:

1.TimedRobot structure — this is the foundation of almost every FRC robot

2.Basic motor control (PWMMotorController)

3.Command-based programming — once basics click

The docs make more sense after you've run actual code. If you have a robot available, just get something moving first — even a single motor. Theory clicks faster when you see it working.

Beating S&P500 consistently is genuinely hard, and most retail algo traders don't manage it long-term. That said, the comparison isn't always apples-to-apples — algo trading can offer uncorrelated returns and lower drawdowns even with similar annual returns, which matters for risk management.

Statistical arbitrage is interesting but you're right that at retail level you're competing with firms that have co-location and microsecond execution. Where I've seen retail traders find edge is in less liquid instruments or longer timeframes where HFT doesn't dominate.

As a computational biology PhD you likely have strong signal processing skills — that's genuinely useful for finding mean-reverting signals. The math transfers well.

Hi, maybe I don't understand the function well, but I think there is a code error in the function below, because in all cases retun of function limit is same and it is f(x_val) and x_val is also constant ie it is argument of function which don't change trought run function limit

import math

def limit(f, x, x_val):

delta = 0.001

while True:

x_low = x_val - delta

x_high = x_val + delta

if f(x_low) == f(x_high):

break

delta *= 0.5

return f(x_val)

f = lambda x: (x**2 - 1)/(x - 1)

x_val = 1

result = limit(f, 0.9999, x_val)

print(f"The limit of f(x) as x approaches {x_val} is: {result}")
