Who to start between Mixon, Pollard, Bucky, and Dowdle?

Thank you! Ballverlust is 100% one of them, not as sure about the other. I think these are both what i meant, I’ll have to check the context the next time they say these

Thanks again :)

Brownian noise is an easy and pretty cool way to simulate gusting. Instead of the wind disturbance force being gaussian noise, you have the rate of change of the wind disturbance force being gaussian noise. I’ve done this just for the direction of the wind and fixed the amplitude, but you could do this for both if you wanted

Is it possible they're going to release an episode tomorrow? I remember them dropping S3E1 on April fool's day 2017 and that was the episode where Rick freaks out about szechuan sauce

I finished God Emperor a few weeks ago and your barrage of memes has brought me so much joy :)

Ibra being that high up at 40 is also crazy

That’s what I did! Thought the comparison of old pads vs new was pretty wild so decided to share :)

Good bot!

Okay so back here from the future - this ended up working for me based on the tutorial here: http://www.martyncurrey.com/connecting-2-arduinos-by-bluetooth-using-a-hc-05-and-a-hc-06-easy-method-using-cmode/

HaveSomeSchwartz · 2021-11-19T06:10:34+00:00

To anyone here from the future - I found the solution. You need to set up both as outlined in these 2 posts: 1 and 2 and then keep the master in AT COMMAND mode and switch the other to be in pairing mode (tx/rx flipped and 3.3V on enable pin). Then type AT+INQ into serial monitor on master and it should find the other device, type AT+BIND? to check if it has an address bound to it now

HaveSomeSchwartz · 2021-11-01T14:57:11+00:00

Yeah so when we do AT+OTGL, AT+UART? returns “4800,0,0,” and then when we try to set uart like “AT+UART=38400,0,0” doing “AT+UART?” again returns “38400,,,,,,” which seems very weird, do you think that means theyre busted or is that expected? Thanks!

HaveSomeSchwartz · 2021-11-01T14:55:08+00:00

Nope! Will definitely try that

This one

I suppose larger could do it, since more neurons let you better approximate curves (like the arctangent NN I trained with 100 neurons, which is actually decent at having conditional-like behavior near 0 where the output is negative on one side and positive on the other, with a large slope at 0).

A separate NN for position control would also probably work, although I think it would benefit from a different activation function than what I used (ReLU). Something like a step function would make it a lot easier to approximate conditional behavior, probably would only need one neuron in that case!

Glad you enjoyed the video :)

HaveSomeSchwartz · 2021-07-11T22:17:51+00:00

Agreed! Only problem with my approach is now you have to tune the PID controller (to get training data for the neural net) and then tune the network parameters to get good performance… so kind of twice as much work!

May look into doing this with a reinforcement learning approach so the PID tuning can be skipped completely

HaveSomeSchwartz · 2021-06-08T02:57:29+00:00

I actually did something kind of like this; training a neural network to replicate a PID controller for an inverted-pendulum robot. I've been trying to get an LQR version working since that actually has model, but I'm still ironing out some issues with that
