A analysis venture led by USC pc science pupil Sumedh A. Sontakke desires to open the door for robots to be caregivers for growing old populations. The workforce claims the RoboCLIP algorithm, developed with assist from Professor Erdem Biyik and Professor Laurent Itti, permits robots to carry out new duties after only one demonstration.
RoboCLIP solely must see one video or textual demonstration of a activity for it to carry out the duty two or thrice higher than different imitation studying (IL) fashions, the workforce claimed.
“To me, probably the most spectacular factor about RoboCLIP is with the ability to make our robots do one thing primarily based on just one video demonstration or one language description,” mentioned Biyik, a roboticist who joined USC Viterbi’s Thomas Lord Division of Laptop Science in August 2023 and leads the Studying and Interactive Robotic Autonomy Lab (Lira Lab).
The venture began two years in the past when Sontakke realized how a lot knowledge is required to have robots carry out primary family duties.
“I began fascinated with family duties like opening doorways and cupboards,” Sontakke mentioned. “I didn’t like how a lot knowledge I wanted to gather earlier than I might get the robotic to efficiently do the duty I cared about. I needed to keep away from that, and that’s the place this venture got here from.”
How does RoboCLIP work?
Most IL fashions learn to full duties by trial and error. The robotic performs the duty time and again to get a reward when it lastly completes the duty. Whereas this may be efficient, it requires huge quantities of time, knowledge, and human supervision to get the robotic to efficiently carry out a brand new activity.
“The massive quantity of knowledge at the moment required to get a robotic to efficiently do the duty you need it to do will not be possible in the actual world, the place you need robots that may be taught rapidly with few demonstrations,” Sontakke mentioned in a launch.
RoboCLIP works in a different way than typical IL fashions, because it incorporates the newest advances in generative AI and video-language fashions (VLMs). These techniques are pre-trained on giant quantities of video and textual demonstrations, in response to Biyik.
The researchers claimed RoboCLIP performs nicely out of the field to carry out family duties, like opening and shutting drawers or cupboards.
“The important thing innovation right here is utilizing the VLM to critically ‘observe’ simulations of the digital robotic babbling round whereas attempting to carry out the duty, till sooner or later it begins getting it proper – at that time, the VLM will acknowledge that progress and reward the digital robotic to maintain attempting on this route,” Itti mentioned.
In keeping with Itti, the VLM can inform it’s getting nearer to success when the textual description it creates observing the robotic comes nearer to what the person desires.
“This new type of closed-loop interplay could be very thrilling to me and can possible have many extra future functions in different domains,” Itti mentioned.

What’s subsequent?
Sontakke hopes that this system might sometime assist robots take care of growing old populations, or result in different functions that would assist anybody. The workforce says that future analysis will probably be vital earlier than the system is able to tackle the actual world.
The paper, titled RoboCLIP: One Demonstration is Sufficient to Study Robotic Insurance policies, was offered by Sontakke on the thirty seventh Convention on Neural Data Processing Methods (NeurIPS), Dec. 10-16 in New Orleans.
Collaborating with Sontakke, Biyik and Itti on the RoboCLIP paper have been two USC Viterbi graduates, Sebastien M.R. Arnold, now at Google Analysis, and Karl Pertsch, now at UC Berkeley and Stanford College. Jesse Zhang, a fourth-year Ph.D. candidate in pc sciences at USC Viterbi, additionally labored on the RoboCLIP venture.
