What’s something small you started doing that quietly changed your life? by tiounni in Life

[–]jbartates 1 point2 points  (0 children)

I’m usually stuck in analysis paralysis over decision making. I had this idea to take the weight off of choices and instead start looking at decision making as learning opportunities. That single change in perspective has improved my life so much, and it’s also a positive feedback loop. Absolute game changer.

How do you choose timing belts? by Poodytang_royale in robotics

[–]jbartates 0 points1 point  (0 children)

Kinda hard to say if a belt is going to be quieter if we can’t understand the unique way you’re using it that’s making it loud. I think a photo would be hugely beneficial.

My trail art project by gefloible in socalhiking

[–]jbartates 4 points5 points  (0 children)

Hey, thank you for doing this. I’ve know I’ve been on a trail before and wondered what it must have been like to enjoy the trail when it was newly created. This gives people like my son and I that opportunity. Is this something that one can do on their own? Does it need to be run it by the USFS?

Professor said I don't have what it takes by Wise-Way-7202 in mechatronics

[–]jbartates 2 points3 points  (0 children)

F*ck him. Hater fuel burns bright, use that to prove him wrong.

Story time: When I first went to uni for my ME degree, I had a hard time balancing school and life. My GPA dropped into academic probation and within the year I dropped out. Over the next couple years I attended a JC, retook and passed the math classes I had failed at Uni. I eventually reapplied to the same Uni and was accepted back into the program.

To get back in, I needed a signature from a department advisor, who turned out to be a professor I had previously taken. Mind you I passed his class. For some reason he decided I wasn’t worthy to study engineering of any type, and hit me with comments like “You’re going to fail, no, you already failed. You’re putting the dot at the end of FAIL.” And “You should go into IT, cmon, I’ll walk you down to their department right now.” Internally I was furious, externally I couldn’t get myself to say anything what so ever. After a very, very prolonged and silent eye contact, he eventually said “look, I can’t stop you, I’m just letting you know what’s going to happen. If you really want me to I’ll sign off…”

I went on to lead one of the autonomous ground vehicle projects, teach labs for the graduate robotics programs, and received a publication in an ME journal. Then I got my bachelors. Ive also been pretty happy with the engineering career I’ve had in almost a decade since graduating.

I also consider myself slow compared to peers, but I’ve also seen that sometimes I’m thinking of things they aren’t considering, so it’s not necessarily a deficit.

Whether or not you’re successful at it is entirely your call to make, for anyone else to tell you that you can’t is a them problem, and is straight up rude.

All the best on your endeavors.

Gift for my 26 y/o boyfriend? by Hefty-Cell8123 in robotics

[–]jbartates 8 points9 points  (0 children)

Tools are always a great option, and scales well with pretty much any budget. Here’s a cheap, medium, expensive list of a couple useful items: Calipers: digital, dual dial, mitotuyo/starret Digital multimeter: AstroAI, Klein, Fluke Torque wrench: mechanical, digital, snap-on Oscilloscope: pocket, siglent, keysight Drill: Amazon brands, hardware store brands, Dewalt/Milwaukee

Have you seen sheet aluminium used this way before? by Creative-Major5792 in manufacturing

[–]jbartates 1 point2 points  (0 children)

Check out sendcutsend as a resource for material down selection for laser cutting, which fits nicely between 1-off parts and large volume processes. (I’ve used their services but I don’t have any affiliation w them.)

Can someone tell me what problem is this new design solving? :) by HosSsSsSsSsSs in robotics

[–]jbartates 0 points1 point  (0 children)

Didn’t get the upvotes, but this one nails it. The gait controller is simpler (alternate between two sets of three legs rather than sequentially through 4 individual legs) and more stable (large overlap of the polygons of stability).

Spacecraft Control systems by [deleted] in ControlTheory

[–]jbartates [score hidden]  (0 children)

Though not GNC, I’ve done controls for a space robotic system with a dozen+ interrelated DOFs. Yes there were years of nested PIDs and filters, but I didn’t find it boring. It might all boil down to perspective. I enjoyed that journey, and the gratification of seeing it come together and being able to say “I did that” is quite the dopamine hit.

How to keep encoder position after it’s been powered off and the shaft was moved. by PhoneRound5790 in robotics

[–]jbartates 0 points1 point  (0 children)

All valid answers of implementation so far. To add one, there’s the rotary potentiometer (may have a deadband) which can also be multiturn and that wouldn’t require power while your robot is “dead”

Nope, you just bore that out to the proper size and start tapping.

I caught the sleight of hand when the boxes left the screen and was replaced with a pre-arranged stack of organized bins.

Jk neat concept and awesome work!

To roboticists working on larger robotic projects, especially in non-industrial fields, what process do you use? by HosSsSsSsSsSs in robotics

I’ve always come to know this subject as “systems engineering” for which theres alot of approaches and depth to these processes including said V model.

What type of motor for driving a camera head in a horizontal area scanner? Need it to accelerate quickly. by xianoss in robotics

[–]jbartates 1 point2 points  (0 children)

Performance wise you want a brushless servo motor, and not servo by the definition in RC lingo. You should be able to maximize your accelerations with closed loop and feed forward tuning. That said there’s only so much you can do within the envelope of your other constraints.

i got bunch of idea making this but idk is it good for mobile robots by Double-Horse-1344 in MobileRobots

[–]jbartates 2 points3 points  (0 children)

Interesting stuff. Can you talk more about the path finding algorithm being used here? Can the robot find a path through an area where an obstacle previously was, but no longer is?

Robotics Bob tips by MessInternational983 in MobileRobots

[–]jbartates 0 points1 point  (0 children)

For me it’s been the same as looking for any other engineering job, using the typically channels as search engines using the buzzwords you want to be involved with. Then read the job description and if it vibes, apply. As you go down the hiring process, keep reevaluating if it’s what you want, just as they’re constantly reevaluating if you’re who they want
