How to Adapt Control Barrier Functions? A Learning-Based Approach with Applications to a VTOL Quadplane

arXiv.org Artificial Intelligence

In this paper, we present a novel theoretical framework for online adaptation of Control Barrier Function (CBF) parameters, i.e., of the class K functions included in the CBF condition, under input constraints. We introduce the concept of locally validated CBF parameters, which are adapted online to guarantee finite-horizon safety, based on conditions derived from Nagumo's theorem and tangent cone analysis. To identify these parameters online, we integrate a learning-based approach with an uncertainty-aware verification process that account for both epistemic and aleatoric uncertainties inherent in neural network predictions. Our method is demonstrated on a VTOL quadplane model during challenging transition and landing maneuvers, showcasing enhanced performance while maintaining safety.


City of Tampere: Finland in Co-operation With Japan in Human-Centred Smart Urban Development

#artificialintelligence

TAMPERE, Finland--(BUSINESS WIRE)--Tampere, one of Finland's largest cities, is the first in Europe to introduce the Liveable Well-Being City indicators, which Japan uses to measure well-being factors from the perspective of residents in its 27 cities. The indicators will provide important information to support knowledge management on the state of the urban environment, the quality of services and the well-being of citizens. The co-operation between Tampere and Japan will start with the application of the indicators developed in co-operation between Smart City Institute Japan and several research institutes and universities. The model utilises both objective and subjective data collected from urban residents to improve well-being and streamline everyday life. The data is an important foundation for knowledge management: it enables cities to identify their success points and development needs from the residents' perspective.


Japanese Engineer Builds A 28-Foot Tall Transformer Humanoid Robot

#artificialintelligence

Engineer Masaaki Nagumo always wanted to build his own Mobile Suit Gundam mecha when he was a child. When he grew up, he transformed his childhood dream into reality. Nagumo created a 28-foot tall, 7 tonnes heavy LW Mononofu robot for his employer, Sakakibara Kikai. The project took six years to complete and is probably the world's largest anime-inspired robot in which you can ride in and control as well. The robot can move its arms and fingers, turn its upper body, and can walk forward and backward with a speed of 1km/hour. The mecha robot also has a metal gun which fires sponge balls at a speed of 87-mph.


Japanese Engineer Builds Huge Robot of His Dreams

Japanese engineer Masaaki Nagumo had always dreamed of operating a robot from "Mobile Suit Gundam." That is the name of a popular Japanese animation television series. It was Nagumo's favorite show when he was a child. Now Nagumo has made the show come to life. He has built a large robot inspired by the machines.


Watch: 28-Feet-Tall Japanese Robot Looks Like A Real World Transformer

International Business Times

A Japanese engineer has created a gigantic robot, one that looks like a real-world transformer and works just as well as any other humanoid on the block. The two-legged robot, dubbed Mononofu, weighs around seven tons and stands a whopping 28 feet tall. However, that should not raise any alarms as the whole thing is controlled by a human rather than artificial intelligence. An operator has to get into the robot's cockpit in order to work the levers designed to control its functions. We have seen many manually-controlled robots in the past, but this one draws particular attention due to its striking resemblance to the machines featured in the Transformers movie series.


Japanese designer realizes his dream by creating 28-foot tall robot

#artificialintelligence

SHINTO, Japan, April 13 (Reuters) - Japanese engineer Masaaki Nagumo had always dreamed of suiting up as a robot from "Mobile Suit Gundam," his favorite animation series growing up. Now he has made it a reality by creating a giant humanoid inspired by the science fiction franchise. Developed at Sakakibara Kikai, a maker of farming machinery, LW-Mononofu is an 8.5-meter (28-feet) tall, two-legged robot weighing in at more than 7 tonnes. It contains a cockpit with monitors and levers for the pilot to control the robot's arms and legs. "I think this can be turned into a business opportunity," Nagumo, 44, told Reuters, noting the popularity of the iconic series that has spawned movies, manga, video games and more. Sakakibara Kikai has developed other robots and amusement machines alongside its main agriculture equipment business and rents them out for about 100,000 yen ($930) an hour, for kids' birthday parties and other entertainment, he said.

Now he has made it a reality by creating a giant humanoid inspired by the science fiction franchise. Developed by Sakakibara Kikai, a maker of farming machinery based in Gunma Prefecture, LW-Mononofu is an 8.5-meter (28-feet) tall, two-legged robot weighing in at more than 7 tons. It contains a cockpit with monitors and levers for the pilot to control the robot's arms and legs. "I think this can be turned into a business opportunity," said Nagumo, 44, noting the popularity of the iconic series that has spawned movies, manga, video games and more. Sakakibara Kikai has developed other robots and amusement machines alongside its main agriculture equipment business and rents them out for about ¥100,000 ($930) an hour, for kids' birthday parties and other entertainment, he said. The company has created robots as varied as the 3.4-meter tall Landwalker, the smaller Kid's Walker Cyclops and the MechBoxer boxing machine -- but the mighty Mononofu towers over them all and executes more complex movements.
