    A large motivation behind this line of home-robot work for me is thinking about the elderly, people with disabilities, or busy parents who simply don't have enough time to do it al…

    In fact, Hello Robot already shared a teleoperated demo of folding shirts! https://www.youtube.com/watch?v=QtG8nJ78x2M&t=180s But yes, a second arm is needed.

    It's always a trade-off! You could have more accurate sensors and motors that are more expensive, or you can have cheaper motors with no sensors and higher accumulated errors. Sinc…

    The title has multiple meanings, some credits definitely should go to OK computer/radiohead, but also "OK Google" for controlling a home assistant, open-knowledge (OK) models, etc.…

    No, although it has some of the same people on the team (aka I'm the first author there, and my advisor is advising both projects :) ) The primary difference is that this is zero-s…

    The mapping process can be done with any RGB-D cameras, we use an iPhone pro but any apple devide with AR-Kit should work. Once we have a sequence of RGB-D images with associated c…

    Thanks! We collect all the data and analyze it post-facto to see what may have caused the failure. For example, on the 5 trials you mentioned, the Realsense gave wrong depth on tra…

    Second that. Something I put out recently had an (admittedly video heavy) webpage that had 1TB of traffic over the past month. Cloudflare handled it for free for me, but at ArXiv’s…

    I'm sorry, should have been clearer. The Spot robot with a manipulator arm (which has been used in some home projects before, see [0]) I believe totals up to about $200K. The base …

    Smaller robots are unfortunately limited in how much force/torque they can apply and how high they can reach, two factors that we found can severely limit the applicability of a ho…

    Tool usage is one of the next ideas we would like to explore; because, if you think about it, the reacher-grabber that is currently used as an end-effector is just another tool. If…

    Great observation! Right now we rely on the out-of-the-box Hello Robots controller [0] implementing position control. Since our policy only predicts a single position into the futu…
