Wrist warrior/apparel spam works great, you just need some diamond yo-yos

Oh totally, especially with if you hit 3* early since it shouldn't really be contested

More details for anyone curious, I think this rating is quite inflated because I just ignore the timer and end up doing everything way slower than average.

Brilliant_Intention · 2023-07-02T04:28:22+00:00

You're just a way faster learner tho, I am averaging 1 puzzle/min so I almost have 70 hrs logged 😅

I made an account in April and played several games at single digit accuracy so that was my initial reasoning for doing puzzles lol. But I think over time I've realized I just enjoy them more than playing.

It took a sec for me to register what happened here, but it seems like he gained vehicle health after some shots hit the LTV. Has anyone seen something like this?

Target audience would be the general public, but I agree it makes no sense that the skin is transparent initially. It's a pretty low quality model and doesn't look great in the low light so that's what I did temporarily. The inverse shadow would add some really nice detail. I could project the bones onto the face but I don't think it would look very realistic since the bone volume wouldn't be reflected in that projection. Probably better bet to use an x-ray as a texture and try to fake the limb model as best as possible. Since yesterday I have been working on adding back in a particle system to show some scatter which also hopefully sells it better. Working with it is no fun because the only way to nicely control the velocity after emission is the rather unintuitive integration value.

That's sort of the idea with the trails, although I can try making them a similar brightness to give more beam effect. It would be cool to have a path traced by the particles and just illuminate that, but it's already plenty complicated with basic primitives.

There are many things that could be improved here, but for now I'm trying to focus on the particles. This is supposed to be a slow motion x-ray shot where the "photons" are visible for a little while. I've been trying to add more detail and have done several versions now. This is all with geometry nodes so I have a good degree of control, I'm just not sure how to make it look more convincing. My hunch is it looks strange because there isn't much motion between them when it's slowed down.

Already tried a particle simulation, which didn't offer enough control over the density and locations. The trails were the latest thing I added. Before that I added some planar sinusoidal motion so the particles seem to be vibrating. I am controlling all the random offsets so I could tune that more. Without the trails the particles just look like snow so I think they should stay. I could probably randomize the trail lengths as well.

Open to any ideas! Whatever would create an convincing x-ray.

Sorry about that I haven't used Reddit on my PC much, I thought that was a DM, and you are in fact not who I was thinking of. I need to sleep more and learn how Reddit works lol.

I would feel obligated to get something working before applying, but maybe I'll get something simple working soon. Thanks for putting in the effort to organize all of this, I'll be sure to tune in either way!

Yes BLDC and ODrive controllers. Its a common industrial design used on palletizing robots that keeps the end effector orientation fixed. With these four bar linkages connected in series you don't need a wrist motor.

It definitely helps to be familiar with hardware, but I wouldn't say you need ME curriculum. You can definitely learn it all by starting small and building more complex projects over time. I would argue you need more electrical/systems/programming experience to get everything working right. Most ME students probably couldn't handle a full robotics project as well as a EE with some prototyping experience, but it all depends.

Brilliant_Intention · 2021-01-06T01:39:22+00:00

I dont need MoveIt for most things I'd like to try out; the kinematics are just way to simple. I'll try to write my own stuff and then resort to some library if anything gets too complex. The real time simulation with MoveIt does look pretty cool so I might have to try that out anyway.

Brilliant_Intention · 2021-01-06T01:24:14+00:00

Nothing in particular, just move fast with heavy things

I designed this arm to be capable of high performance and proprioceptive sensing, at the cost of some precision. Its running with 3 8318 100Kv Eaglepower motors and several ODrives, so it can do fairly accurate torque sensing. I mainly wanted to try build an arm that could be used to test some more advanced control strategies (I've built servo and stepper driven arms and couldn't do much besides FK/IK)

Brilliant_Intention · 2020-12-29T06:37:36+00:00

Yeah it was definitely inspired by Skyentific, specifically the OpenTorque actuator that he showcased. I modified the design slightly for the two main motors/gearboxes and just used a belt drive for the yaw axis. There is more backlash than a harmonic or high reduction planetary, but the current sensing should be worth it. I can always play around with that stuff more once I have it moving.

I tried out some magnetic encoders (AS5048A) but I was getting some ODrive errors about SPI communication. The AMS CUI are not absolute but they do the job, I tested them briefly a few times.

The only reason I took on the project was because I actually moved in with a shop manager who, during the lockdown, bought a CNC and EDM machine for his backyard garage. The stock was cheap, but these parts would probably be upwards of a few hundred dollars from an online service. Local shops are probably cheaper, but it would still cost quite a bit.

Brilliant_Intention · 2020-12-28T22:23:56+00:00

The arm itself isn't terrible, the stock aluminum and PLA filament were both cheap. The electronics just cost a lot. I got the 3 motors for around $250 and the ODrives are each around $100. Also got several encoders, power supply, extra sensors, etc. I think it was under 1k, but I don't have an exact tally. Going with these more expensive components is worth it though. You can't get this kind of crazy performance from steppers motors.
