It’s great! How did you do it? I printed it out months ago and wondered how to do one myself

Great project! It uses the motion library from the artist quaternius. He has some wonderful free and low-cost models.

After the upgrade (which I even don't remember allowing), I had double UEFI entries. Cost me nearly a day to be able to boot windows (and it works only from the Linux boot menu)

Will it run on the Quest headset? It’d be nice to develop rust extensions for Godot in a real IDE. Price seems fair to me too. Will there be a means to test the software first?

I’m kind of disappointed that the earbuds mentioned in the text aren’t shaped like gummy bears (and the power bank not like a pack thereof)

This should be listed on European-alternatives.eu. I was just looking for something similar with little success. Thanks for sharing.

Does this work for private/closed source project? Where are the servers located and how is it financed?

A motion capture App that uses a probabilistic approach to fully automate the labeling and mapping process. I have this algorithm for quite a while in my head and want to use it to get up to speed with Godot and Rust. Intended to work with

It’s an extrapolation beyond known data that is inaccurate. I wonder why this can’t be detected during inference

Depends entirely on the application I guess, but you'd get further for sure. Either way you are now confronted with more complex cable management and maintenance, and additional weight. You'd at least get around gravity compensati
44.
by stefanka 1y ago
I agree. But even then elasticity had to be taken into account (and maybe even gravity), if the object is very delicate.

Ooooh. For _that_ application you better have either enough elasticity or reliable force/torque sensors and a good control in place.
47.
by stefanka 1y ago
It’s one of best designs I have seen, I admit. But for that price you cannot get absolute encoders outside the motor, reliable force/torque sensors (think picking up a strawberry), tendons (thread below). It might be too limited for re
48.
by stefanka 1y ago
If space permits you should add absolute encoders in the joints. In a finger that’s likely a challenge. In an arm, that’s easy
49.
by stefanka 1y ago
If you can get a feedback loop at the respective joint, then yes, this might be enough. In case of an arm (not this hand), you can often only observe the end of a chain, and then, that’s more complex

Or both …

by stefanka 1y ago
You don't necessarily need neural networks for that, there are more specialized function approximations that learn faster and enable life-long learning for kinematics/dynamics and extrapolate better than NN which are more general

by stefanka 1y ago
Not to mention that they easily break and are annoyingly tedious to be replaced (I had to assist often enough on such "surgeries" in our lab)

Roboy used dyneema tendons if I recall correctly. Fluidic actuators is another option. IMO, additional sensors and sensor fusion are necessary but this will raise the costs and demand to control software significantly. We are researching hu
54.
by stefanka 1y ago
Most tendons materials are elastic. That lead to create calibration problems and require proprioceptive sensors in the hand

Safety in rufst is not only about memory safety. It’s also about avoiding unpredictable behavior.

One mentioned glue traps. What’s that and why is it used? Sounds like a horrible way to catch birds.

by stefanka 1y ago
I like that this looks like a very ethical and "fair" use of the LLM technology

by stefanka 1y ago
We have also a pretty decent amount of experience with (pulse/spiking) artificial neural networks in analog hardware, e.g. [1]. Very Energy efficient but yet hard to scale. [1] https://www.kip.uni-heidelberg.de/Veroeffe

It is not that complicated or time-consuming to do the transformation manually. On the contrary, it's even fun and a good practice (but admittedly, I do have a rather conservative view on the matter)

It is indeed great for creating a prototype. After that, one can gradually migrate to Rust go benefit from faster execution times. The Rust bindings are in a pretty decent shape by now https://godot-rust.github.io/
