| Its actually easier than you would expect! you can use a
| process in image processing called "thresholding" where you
| basically filter the RGB or color values. Its very common and
| a little "hack" on compute. Computers "look" at images or
| video by converting the camera data into large matrices. Red
| would be 1 matrix, blue another, green another. Instead of
| this, you typically convert it to black and white but you can
| do any color you want, depending what youre looking for. This
| reduces your compute from 3 matrixes to 1 and makes your
| functions exponentially faster. Someone can help me on O(n)
| notation lol.

| I've been generally curious about the benefits of the humanoid

|
| I'll admit I don't know much about the state of the enterprise
| robotics/automation market but it would seem like the market
| would be limited by the fact that: 1.) The companies able to
| afford such robots would have much higher throughput capacity
| requirements and would want to setup much more customized
| automation. 2.) The companies in the sweet spot in terms of lower
| throughput capacity requirements would not be able to afford the
| upfront cost of such robots.
|
| I think the primary use case would be perhaps if these could
| actually get in the sub $100K-$150K range end cost wise which
| seems a bit far off given the complexity I'm seeing here. Perhaps
| the idea is to go for the long game?
|
| It feels like a version with just the top half of the humanoid
| would be more interesting if it could cut costs particularly
| since this thing likely needs to be tethered for reliable power
| and communications in a factory automation setting.

|
| I'm actually really excited about the current state of
| robotics, and wouldn't be surprised if it ends up being the
| most impactful outcome of the most recent AI developments over
| the next 10-15 years.
|
| I know there's a lot of hate for Elon Musk / Tesla, but at the
| end of the day he's just the money guy for some really great
| researchers out there.

| This reads like they haven't already taken that risk with
| fatal consequences.
|
| Not seeing how a robot, literally marketed as being powered
| by the FSD computer, could actually work unless the
| underlying FSD system actually works. Which it doesn't.
| elfbargpt wrote:
| I'm not sure about their marketing claims, but the robot in

| sensors, but I doubt there's a ton of overlap between the
| underlying system and the directions it gives. AGI doesn't
