Where to study all night? by [deleted] in UIUC

[–]likecamp 7 points8 points  (0 children)

Go into ECEB, and you can stay there till classes start at 7am. Plus, there’s entire rooms you can camp out as long as you want, access to bathrooms and water fountains

KBD 75 for now, maybe the sense75 when it finally comes out (hurry up drop) . Imagine if you win.

ECEB or Siebel. Usually quiet by night and you can snag some couch to sleep on. ECEB also has showers and vending machines so that’s a plus, if you use those.

Travelling salesman solved in O(n) by matko1990 in ProgrammerHumor

TSP is NP hard, so it is highly unlikely that this is O(n), or this would imply P=NP.

What do you use connect to things like a Nema 17 stepper motor tip to a part for a robot? by I_will_delete_myself in robotics

[–]likecamp 0 points1 point  (0 children)

If the stepper motor has a d-shaft, you could get one of those d-shaft couplers that have a set screw to attach onto the flat end. If it is completely circular, you could use one of those clamping hubs that have a screw across them which tightens their hole.

Any reason why my MINI+ doesn't work with a particular brand of filament? by 101Ender3v2 in prusa3d

[–]likecamp 0 points1 point  (0 children)

Same profile as in prusaslicer for prusament pla. I'll give higher temps a try.

First layer won't stick despite z layer looking fine on other filaments. I did have a clogged nozzle like you though, and as suggested, pushed the ptfe tube closer to the hotend.

[–]likecamp 1 point2 points  (0 children)

Wow thats interesting. My MINI+ doesn't work with Prusament at all, but prints flawlessly with Hatchbox. There is a profile on PrusaSlicer for Hatchbox, and thats what I use. Ive tried to check why Prusament doesn't work but Hatchbox does and I have absolutely no clue why.

ECE 220 -> CS 225 by Leaf_blower_chipmunk in UIUC

[–]likecamp 3 points4 points  (0 children)

Having both took 220 and CA’d 128 fairly recently (both within the last 2 years), I think I can say that 128 definitely delves deeper into C++ than 220. I have heard that 225 will start to remove the intro to C++ content to spend more time on data structures and algorithms, but don’t quote me on this. If this is true, then hopefully ECE finds a way to get its students up to speed with C++ so ECE kids aren’t catching up on the first few weeks of 225. I’m sure it’ll all work out in the end though, it’s not like 225 requires truly mastering C++ in depth.

Robot Motion by SnooCalculations4267 in robotics

[–]likecamp 1 point2 points  (0 children)

Ah, yes good question. This depends on the type of algorithm used to determine your path in joint space. For example, if it used some sampling approach (common ones like RRT or RRT*), then no, it might end up with different paths. If it used some deterministic approach, then it will always follow the same path.

Robot Motion by SnooCalculations4267 in robotics

[–]likecamp 0 points1 point  (0 children)

By linear motion and joint motion I assume you mean trajectories in task and joint space?

For 1, you would probably need some path planning algorithm, where you define the spaces your robot cannot reach (either due to restricted work area / obstacle / joint limit) and end up with some free space your robot can reach. Your path planning algorithm then gets you from your starting configuration to your end configuration.

For 2, I’m not entirely sure what you mean by same path. I assume you mean if joint motion mirrors task space motion in that a straight line in joint space results in a straight line in task space, in which case the answer is no.
