More details: https://en.m.wikipedia.org/wiki/Flyby_anomaly …

“The flyby anomaly is a discrepancy between current scientific models and the actual increase in speed observed during a planetary flyby by a spacecraft. Spacecraft have greater speed than scientists had predicted, but thus far no convincing explanation has been found.”

CNNs need flat space and work best on 2D and 3D images. A subfield called geometric deep learning attempts to provide convolution operators for non-Euclidean spaces, such as the surface of a sphere: “An Idea From Physics Helps AI See in Higher Dimensions”https://www.quantamagazine.org/an-idea-from-physics-helps-ai-see-in-higher-dimensions-20200109/ …

Really exciting work. Congrats to the Covariant team!

It also sounds like they’ve done true end to end learning of the entire robotics problem, against a single deep net. I wonder how they managed to have such a large network in the RL loop; traditionally deep RL nets are quite simple

They’ve created a single deep net that can actually work with different grippers! “We can condition a single neural network on both what it sees and the end-effector it has available. This makes it possible to hot-swap grippers if you want to.”

It sounds like there is a bit of imitation learning in the mix too: “But you don’t want to just use RL, because RL is notorious for taking a long time, so we bootstrap it off some imitation and then from there, RL can complete everything.”

I’d love to know more details about this: “Our system has few-shot adaptation, meaning that on-the-fly, without us doing anything, when it doesn’t succeed it’ll update its understanding of the scene and try some new things.”

It sounds like they trained on both sim2real and real data as well

The robot is able to perceive pretty challenging situations: “it is able to detect glossy, shiny, and reflective products, including products in plastic bags. The product range is nearly unlimited, and the robotic picking station has the same or better performance than humans.”

The robot is also working in the real world: “the system has been up and running reliably and cost effectively in a real warehouse in Germany for the last four months. “

“It has to be a single network able to handle any kind of [product], any kind of picking station. In terms of being able to understand what’s happening and what’s the right thing to do, that’s all unified.” They call it Covariant Brain.

It sounds like they have one giant neural network that generalized across customers, which is exciting: “What couples the vision system to the suction gripper is one single (and very, very large) neural network, which is what helps Covariant to be cost effective for customers.”

They use a pretty standard robotics hand with a suction gripper, as well as simple standard 2D cameras (no lasers, etc).

They focused on the picking problem: “taking products out of one box and putting them into another box”

Many robotics startups IMHO focus on the tech first and choose sectors that already have rock bottom labor costs or involve commodity products, which makes it very hard for smarter robots to compete. Looks like Covariant did a good job along the product dimension.

One thing about logistics and warehouses is it can’t just be outsourced to other countries, where robots would have trouble competing — by definition most logistics warehouses are near the customer, so robots can be competitive

“logistics especially is just hurting really hard for more automation. And the really hard part of logistics is what Covariant decided to tackle.”
