The dawn of thought-controlled robotics

Robotics is a discipline that deals with designing, building and programming machines capable of performing tasks autonomously or in collaboration with humans. Robotics has applications in many areas, such as industry, medicine, agriculture, exploration, security and entertainment. However, to interact with robots, humans often have to use physical devices, such as keyboards, mice, joysticks, remote controls or sensors, which can be inconvenient, limiting or unintuitive.

To overcome these obstacles, some researchers are developing brain-robot interface (BRI) systems, which allow users to control robots by thought alone, without the need for any physical device. These systems are based on EEG (electroencephalography) technology, which records and interprets the electrical signals produced by the brain when a person thinks about an action or object.

An example

An example of a BRI system is NOIR (Neural Signal Operated Intelligent Robots), developed by a group of researchers at Stanford University. NOIR is a generic, intelligent system that allows users to command robots to perform everyday tasks through brain signals. Through this interface, users communicate their objects of interest and actions to the robots, using two types of EEG signals: SSVEP (steady-state visually evoked potential) and MI (motor imagery).

SSVEPs are signals generated by the brain when a person looks at a visual stimulus that flashes at a certain frequency. NOIR uses screens showing different objects with different blinking frequencies, and decodes the SSVEPs to understand which object the user wants to manipulate. MIs are signals generated by the brain when a person imagines moving a body part. NOIR uses machine learning algorithms to decode MIs and understand how the user wants to interact with the object. In addition, NOIR uses a safety mechanism that captures jaw muscle tension to confirm or reject decoding results.

NOIR offers various robotic skills, which can be combined to perform complex tasks. The robotic skills are based on 14 parameterised primitive skills, such as picking up, putting down, pushing, cutting, pouring, mixing, switching on, switching off, opening, closing, writing, drawing, playing and singing. These skills can be applied to different objects and contexts, and can be adapted to the preferences and intentions of users.

NOIR demonstrates its success in a wide range of 20 challenging activities typical of everyday life, such as cooking, cleaning, taking care of oneself and having fun. For example, users can control a robot to bake a cake, wash the dishes, sweep the floor, turn on the TV, write a letter, draw a flower, play the piano and sing a song, simply by thinking.

The system’s effectiveness is enhanced by its synergetic integration of robotic learning algorithms, which enable NOIR to adapt to individual users and predict their intentions. The robot learns the user’s object, skill and parameter selections in a few-shot manner, thus reducing the effort and time required for decoding.

The work of Stanford researchers represents a breakthrough in research on thought-controlled robotics, and opens up new possibilities for human-robot interaction based on direct, neural communication. This type of interaction could have benefits for many categories of people, such as the disabled, elderly, sick or isolated, who could use robots to improve their quality of life and autonomy. However, thought-controlled robotics also presents challenges and risks, such as security, privacy, liability, trust and user acceptance, which require further study and regulation.

Finally some initiative in the school

“Video Project on Digital Literacy and Public Debate Presented at Palazzo Cesaroni Event”
Awareness-raising project:
The project aims to raise students’ awareness of the conscious use of the Internet and digital tools, promoting them as useful for the development of public debate.
The students made a video on the themes of humanism, democracy and digital inclusion, which was screened during the closing event at Palazzo Cesaroni.

Digital Humanism’ for a conscious use of the Net Company Name

Summary

School project: It is a project that involved students from a number of Umbrian schools, to educate them in the conscious use of the Internet and digital tools, also as a means for public debate.
Themes addressed: The project covered the topics of humanism, democracy and digital inclusion, with a focus on the rights and duties of online citizens.
Video realised: The students produced a video on the project themes, which was screened during the closing event at Palazzo Cesaroni, seat of the Regional Council of Umbria.
Interview: The news report interviewed Elena Veschi, President of Corecom Umbria, and Marco Squarta, President of the Regional Council, who expressed their appreciation for the project and the students’ work.
