Why All Companies Need An AI Strategy

This Is Why All Companies Need An AI Strategy Today Rita Waite (@ritacwaite) is a Growth Strategy & Investments Manager at Juniper Networks, where she focuses on emerging networking technologies. She is Juniper’s representative and observer to the Board of Directors of several portfolio companies. Rita is also a VP of West-to-West, an organization that promotes and supports Portuguese entrepreneurship in Silicon Valley. Rita graduated from the University of San Diego with a B.A. in Economics. The following is a guest post by Rita C. Waite, a Growth Strategy & Investments Manager at Juniper Networks. Any AI effort will rely on three main building blocks: data, infrastructure, and talent. Artificial Intelligence (AI) is fundamentally changing how businesses operate across all sectors, including manufacturing, healthcare, IT, and transportation. Advancements in AI over the last decade are presenting opportunities for companies to automate business processes, transform customer experiences, and differentiate products offerings. AI pioneers like Google and Amazon, who […]

Slippage applications with snake robots

Studying slippage on pushing applications with snake robots  (뱀 로봇을 이용한 밀기 공부시 미끄러짐 연구) Abstract In this paper, a framework for analyzing the motion resulting from the interaction between a snake robot and an object is shown. Metrics are derived to study the motion of the object and robot, showing that the addition of passive wheels to the snake robot helps to minimize slippage. However, the passive wheels do not have a significant impact on the force exerted onto the object. This puts snake robots in a similar framework as robotic arms, while considering special properties exclusive to snake robots (e.g., lack of a fixed-base, interaction with the environment through friction). It is also shown that the configuration (shape) of the snake robot, parameterized with the polar coordinates of the robot’s COM, plays an important role in the interaction with the object. Two examples, a snake robot with two […]

multiple robot path planning algorithm

A new multiple robot path planning algorithm: dynamic distributed particle swarm optimization Asma Ayari* and Sadok Bouamama Abstract Multiple robot systems have become a major study concern in the feild of robotic research. Their control becomes unreliable and even infeasible if the number of robots increases. In this paper, a new dynamic distributed particle swarm optimization (D2 PSO) algorithm is proposed for trajectory path planning of multiple robots in order to find collision-free optimal path for each robot in the environment. The proposed approach consists in calculating two local optima detectors, LODpBest and LODgBest. Particles which are unable to improve their personal best and global best for predefined number of successive iterations would be replaced with restructured ones. Stagnation and local optima problems would be avoided by adding diversity to the population, without losing the fast convergence characteristic of PSO. Experiments with multiple robots are provided and proved effectiveness of […]

Soft pneumatic actuator, Soft gripper

Comparison of different soft grippers for lunch box packaging Zhongkui Wang†Email authorView ORCID ID profile, Mingzhu Zhu†, Sadao Kawamura and Shinichi Hirai           †Contributed equally    Robotics and Biomimetics    2017 4:10                   https://doi.org/10.1186/s40638-017-0067-1    ©  The Author(s) 2017           Abstract Automating the lunch box packaging is a challenging task due to the high deformability and large individual differences in shape and physical property of food materials. Soft robotic grippers showed potentials to perform such tasks. In this paper, we presented four pneumatic soft actuators made of different materials and different fabrication methods and compared their performances through a series of tests. We found that the actuators fabricated by 3D printing showed better linearity and less individual differences, but showed low durability compared to actuators fabricated by traditional casting process. Robotic grippers were assembled using the soft actuators, and grasping tests were performed on soft paper […]
