The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices.
Encoding matrices as graphs is a cheat code, making complex behavior simple to study.
Let me show you how!

We trained a transformer called VIMA that ingests *multimodal* prompt and outputs controls for a robot arm. A single agent is able to solve visual goal, one-shot imitation from video, novel concept grounding, visual constraint, etc. Strong scaling with model capacity and data!🧵

For the robotics nerds, our robot aims to be fully autonomous and uses with MPC/RRT* for planning and control, behavior trees using behaviortree.dev (thank you🙏! ), apriltag localization, and kalman filtering #ros

What would you do if robotic hands with touch sensors can be designed in a manner of minutes? It's actually possible now: robohands.csail.mit.edu
Our framework furthers the possibility of co-design of control and hardware by expressing hand designs as grammars and deformations!

Copilot needs to learn to convert python code to numpy/torch or atleast hint at parts of the code that can be simplified through numpy ops.
People in robotics startups. I ask for your help with a question.
Do you make a simulation model of your custom robot for active development? Or build directly on hardware?
If yes, how many days/months did you take to develop it? And was it worth it? (Note: Startups)

Real-to-sim for deformables brings a challenge of estimating the state & its evolution in time🪢We represent noisy state estimates (from videos) as distributional embeddings, and show how to construct these automatically, without feature selection/tuning: arxiv.org/abs/2112.05068

Our algorithms should be doing this more often when they are uncertain of what action to take, not just when they get stuck.

Modern times in Estonia. A robot which had become stuck in the snow, saw me coming, and asked with a synthesised voice whether I could help out. So I did, and both of us carried on with our day.

RoboStack is great! Our robotics club has been using RoboStack for the past semester and found it easy for new members to get ROS on their system. Congrats!

Incredibly happy that our @RoboStack paper has been accepted to the @ieeeras Robotics & Automation Magazine 
. @RoboStack brings together #ROS @rosorg with @condaforge and @ProjectJupyter. Preprint: arxiv.org/abs/2104.12910. Find out some key benefits in this
