New Gaussian splatting representation based on polyline primitives! The primitives are optimized directly from images and can form long, connected chains. Perfect for reconstructing strand structures (spaghetti, hair, etc.) and it matches 3DGS performance on general scenes.

📢📢📢 Introducing Spaghetti Splatting

3DGS is a convolution of a Dirac with a Gaussian Kernel. We provide a strict generalization of 3DGS, extending its Dirac mass to lines and curvilinear structures

Pretty cool that this works with only 15 min of data!

You can take a robot policy that doesn't do mobility and turn it into one that can move around (mobility + manipulation) with a very limited robot data.

Rhoda AI @RhodaAI Nov 3

We taught a robot how to move around in only 15 minutes.

That’s all the mobility data our Direct Video-Action-powered robot needed to accomplish a task that requires mobility and manipulation.

It's amazing how much you can scale up the output resolution and speed of image generation models without any re-training.

The trick here is to leverage the more local behavior of attention in later diffusion steps to accelerate attention within diffusion transformers.

We gave our robots a sense of touch!

Excited to finally share this work with @AndrewEJXie, @leooeld, and the @rhoda_ai team!

Some technical details on the tactile sensor and robot policy: 🧵

Rhoda AI @RhodaAI Oct 14

What can a robot do without vision?

We gave our robot a sense of touch and showed it can recognize and retrieve objects with its cameras blindfolded.

Introducing Rhoda’s new tactile sensor—it feels pressure, texture, vibration, slip, and temperature, just like your fingertips.

There is a lot to appreciate in these demos—recovery from errors, the length and complexity of the demonstrations, and targeting actual, real-world tasks.

Rhoda AI @RhodaAI Oct 6

Continuing our RhodaAtWork series with another look at Direct Video-Action (DVA) in action.

This time, a single model handles multiple tasks across two home appliances: refrigerator EPS foam installation and washing machine drain hose routing.
