In Roberto Calandra's "Fall 2022 GRASP SFI Roberto Calandra, Meta AI" video, he discusses the design and use of a fast simulator for vision-based tactile sensors. The video also discusses the open source Pi Dutch machine learning library dedicated to touch processing, and how it can be used to train and compare models without having to write boilerplate code.

00:00:00 Roberto Calandra, a researcher at the Meta AI Institute, discusses the need for robots to be able to interact with and understand their surroundings in a more natural way in order to be more effective in tasks such as disaster relief and exploration.
00:05:00 Roberto Calandra, a meta AI researcher, discusses the importance of touch in robotics and the challenges of developing reusuable touch components.
00:10:00 Roberto Calandra, Meta AI's CEO, discusses the company's work developing a tactile sensing ecosystem, which he believes will be as successful as computer vision and natural language processing. He also discusses the company's plans for Touch Processing, which he believes will be focused on making sense of touch in other sensor modalities.
00:15:00 In his talk, Roberto Calandra discusses the history of touch sensing, overviews touch sensing hardware and how it can be used in various applications, and introduces a vision-based tactile sensor.
00:20:00 The video demonstrates how a USB 2 interface can be used to connect a webcam sensor to a computer, allowing anyone to start using tactile sensing. The sensor has a very high resolution (15-20 microns), is compact, and is open source. In the last two years, over 20 universities have replicated the design of the sensor and adopted it into their research. In partnership with jets, we are gifting the rights to jazza to reduce the cost of the sensor for the general public.
00:25:00 Roberto Calandra's "Fall 2022 GRASP SFI Roberto Calandra, Meta AI" video discusses the design and use of a fast simulator for vision-based tactile sensors, which allows for research into tactile processing. The video also discusses the open source Pi Dutch machine learning library dedicated to touch processing, and how it can be used to train and compare models without having to write boilerplate code.
00:30:00 The talk provided a overview of Roberto Calandra's work on meta-AI, which focuses on building frameworks and training models that can be used to benchmark and improve performance across different sensors and tasks. This is important in order to enable standardized research and collaboration within the touch sensing community.
00:35:00 Roberto Calandra discusses applications for touch sensing, including prostheses, the metaverse, and agricultural robotics. He also discusses challenges and potential future applications for touch sensing.
00:40:00 Roberto Calandra, a researcher in the field of machine learning, presents a paper on the use of touch in learning how to play piano. The paper discusses various tasks involving touch, including active tactile exploration and 3D reconstruction from vision and touch. The paper also discusses the importance of human perception in manipulation, and how robots currently lack the ability to achieve this level of dexterity.
00:45:00 Roberto Calandra, a professor at the University of SFI, discusses how his team's work on learning to manipulate objects with only private information (position and velocity) using a simulator and real robots has been very successful. He also discusses the importance of touch in human physiology and how his team's work is intended to make touch sensing more practical and useful in the real world.
00:50:00 Roberto Calandra discusses the potential of touch sensing in 2021 and 2022, focusing on the Revolutions in audio, and how Meta AI's simulation capabilities make the technology more accurate. He also mentions that the low-pass filter dynamics of the gel is easily simulated, and that vibrational detection is an important factor in early detection of sleep.
00:55:00 Roberto Calandra, a professor of computer Science at the University of Toronto, discusses the importance of having a touch-based interface in manipulation tasks, and how it is important to ground tactile perception in what humans feel like when experiencing playback and touch. He also discusses the difference between having a finger touching something and not.

01:00:00 - 01:00:00

In the video, Roberto Calandra discusses the value of touch sensing for reducing uncertainty. He argues that touch is more effective than other senses in this regard, and that this hypothesis is likely to be true.
