Robots.txt

Robots.txt, the file behind the Robots Exclusion Protocol, is a plain-text file at a website's root telling web crawlers which parts of the site they may fetch.

RobotShop

RobotShop is a Canadian online retailer and marketplace specializing in robotics technology, founded in 2003 by Mario Tremblay and based in Mirabel, Quebec, shipping to more than 200 countries.

RobotStudio is an ABB Robotics PC application for modeling, offline programming, and simulation of industrial robot cells, first released in 1998 and built on the ABB Virtual Controller.

Robotti

Robotti is a driverless agricultural field robot developed by the Danish company AgroIntelli, sold from 2018, that pulls conventional implements such as seeders, hoes, and sprayers.

RoboTuna

RoboTuna is a robotic fish built at MIT in the early 1990s, led by Michael Triantafyllou, to imitate a bluefin tuna and test fish-like propulsion for underwater vehicles.

RoboTwin is a simulated dual-arm robot manipulation benchmark and synthetic-data generator for vision-language-action models, introduced at CVPR 2025 and expanded into RoboTwin 2.0 in June 2025 with 50 tasks, domain randomization, and an official leaderboard.

Robson Conceicao

Robson Donato Conceicao, 'Nino' or 'O Brabo', Brazilian boxer born 1988 in Salvador; first Brazilian Olympic boxing gold (Rio 2016, lightweight 60 kg, beat Sofiane Oumiha) and WBC super featherweight world champion 2024.

Robson Green

Robson Green (Robson Golightly Green) is an English actor, singer, and presenter born 1964 in Hexham, Northumberland. Known for Soldier Soldier, Reckless, Wire in the Blood, and as DI Geordie Keating in ITV's Grantchester; half of Robson & Jerome, whose 1995 "Unchained Melody" topped the UK chart for seven weeks; runs the production companies Coastal Productions and Rivers Meet in north-east England.

Robust control

Robust control is a design approach in control theory that guarantees stability and performance for all plants within a predefined uncertainty class, arising in the early 1970s.

Robust decision making

Robust decision making (RDM) is an iterative stress-testing method developed at RAND by Robert Lempert, Steven Popper, and Steven Bankes that seeks strategies performing well across many plausible futures.

Robust Intelligence

Robust Intelligence was an AI security startup founded in 2019 by Yaron Singer and Kojin Oshiba, best known for its AI Firewall and its 2024 acquisition by Cisco.

Robust optimization

Robust optimization is a mathematical approach to decision-making under uncertainty in which a solution is chosen to perform well against worst-case parameter values inside a prescribed uncertainty set, rather than against expected values.

Robust PCA

Robust PCA (RPCA, robust principal component analysis) is a family of PCA methods reliable under gross corruption, splitting a matrix into a low-rank part plus sparse outliers.

Robust principal component analysis

Robust principal component analysis (RPCA) decomposes a data matrix into a low-rank component and a sparse component of grossly corrupted entries, keeping principal components intact despite outliers.

Robust regression

Robust regression, also known as robust linear regression, is a family of methods for fitting regression models that stay reliable when data contain outliers or violate the assumptions behind ordinary least squares.

Robust statistics

Robust statistics is the branch of statistics that designs estimators and tests that resist outliers and small deviations from model assumptions, pioneered by Tukey and Huber in the 1960s.

Robust tube model predictive control

Robust tube model predictive control, or tube MPC, is a robust control method in which a nominal trajectory is planned online while feedback confines the uncertain state to a tube around it.

Robust.ai

Robust.ai is an American robotics company founded in 2019 in Palo Alto, California, by Gary Marcus and Rodney Brooks, best known for its Carter warehouse robot and Grace software suite.

Robustness (analytical chemistry)

Robustness, also called ruggedness, in analytical chemistry is an analytical method's ability to maintain acceptable performance when operating parameters like temperature, pH, and flow rate are deliberately varied within small, realistic limits.

Robustness analysis

Robustness analysis is a strategy in model-based science where a result is tested across varied model assumptions; a surviving result is called robust, and its invariance suggests the model's core assumptions drive the outcome.

Robustness testing

Robustness testing is a black-box software testing method that checks how a system behaves under invalid inputs and stressful conditions, using a weak oracle that only requires the software not to crash or hang.

Robux

Robux is the virtual currency of Roblox, bought with real money or earned by creators, who can exchange qualifying earnings for cash through the Developer Exchange program.

Robyn

Robyn (Robin Miriam Carlsson, born 1979, Stockholm) is a Swedish pop singer, songwriter, producer, and DJ; founder of Konichiwa Records, creator of Body Talk and "Dancing on My Own", and maker of the 2026 album Sexistential about IVF and single motherhood.

Robyn Bernard

Robyn Bernard (1959–2024) was an American actress, sister of Crystal Bernard of Wings, who played singer Terry Brock on General Hospital in 145 episodes from 1984 to 1990, and appeared in Diva and Betty Blue.

Robyn Cara

Robyn Cara is an English actress born in 1995, known for Emmy Sizergh in Netflix's Bodkin (2024), Jen in Apple TV+'s Trying, Kayla Afzal in Ackley Bridge, and Kelly Riker in USA Network's The Rainmaker (2025), after training at the Birmingham School of Acting.
