Hypothesized mechanism: lipo charge ICs stop charging below a certain cutoff voltage for safety reasons. Sitting in a discharged state for too long will cause them to gradually self-discharge below the cutoff voltage. Heating them up increases the voltage which might be …
Wondering what’s the deal with robot art? Definitely give this 5min video a watch!
Peter gives an amazing review on the evolution of robot painting, highlighting some past robots, future ideas, and why you should care. Robots advancing art AND art advancing robotics.
Our ICRA@40 video shows some of the history of robot painting projects, the challenges these roboticists faced, and how they made core contributions to the field of Robotics. It doesn't have to be Robotics for Arts, it can be Arts for Robotics!

Obviously, major thanks to my advisors & collaborators!
If your robot motion is jerky, there’s a good chance you just need to feed it better-timed trajectories. Try retiming using our code! arxiv.org/abs/2309.10176

.@gtcomputing ❤️ getting up close action shots with the artist & roboticist team of Tristan Al-Haddad and Ph.D. candidate in robotics and friend Gerry Chen at the GT Library of their work on the Polycentric Truthes mural! Read more here library.gatech.edu/news/poly… @gchenfc
Thanks so much @ChristaErnst1 !
We'll be finishing up the painting at Price Gilbert library tomorrow and Thursday - DM me for deets if you're interested in watching it paint!
No sweat if you can't make it on short notice: mural & robot will be on display for a little while :)

Huge thanks @MissManci organizing @GTLibrary Artist-in-Residence program for Tristan Al-Haddad & me :)
Excited to share that our work on trajectory retiming was accepted to #ICRA2024!
Traditional "time-optimal" trajectory retiming saturates control limits to minimize time (bang-bang), but this has negative consequences on closed-loop control stability and premature robot/tool wear
We replace the time-optimal objective with quadratic terms to balance multiple objectives such as control margin and speed. We leverage the special structure of the resulting QP to solve it in O(n) using factor graphs!

[4/5] Style & character consistency among pages was lacking. I didn't try very hard on this, and I know there's several recent works addressing this (especially re: video gen), but out-of-box, trying to get *multiple* characters accurate with consistent styling is hard.
ALT Side-by-side images depicting the same character as 3-4 years old on page 11 but then younger than 1 year old on page 15
Overall, a fun experience that is leaps and bounds better & faster than I could do myself, but still took ~7hrs for 20 pages, with most of the time being editing-out characters. Could probably re-do in ~3hrs knowing what I know now.
