Bite Acquisition

In robot-assisted feeding, the stage in which a robot uses a utensil to pick up a piece of food from a plate or bowl. Bite acquisition is a core technical challenge in assistive feeding robotics because foods vary enormously in compliance, friction, and geometry (e.g., spearing…

Bite Transfer

In robot-assisted feeding, the stage of the feeding cycle in which a robot arm moves food already on a utensil from a pickup location into the user's mouth. Bite transfer is distinct from bite acquisition (picking food up from a plate) and is the most physically intimate and…

Delegation (Human-Robot Interaction)(also: Delegation, Task delegation to robot)

In human-robot interaction, the explicit transfer of a task or decision from a human to a robot. Delegation is a form of shared control in which authority for a specific subtask — for example, asking bystanders to step aside, announcing an obstacle, or choosing a path around a…

Mutual Support(also: Mutual support in HRI, Mutual assistance)

In accessibility and human-robot interaction research, a framing that moves beyond one-way robot-supports-user or user-supervises-robot models toward a bidirectional relationship in which each party compensates for the other's limitations. For a blind user travelling with an…

Omakase(also: Omakase mode, I leave it to you)

A Japanese word — literally 'I leave it to you' — adopted in human-robot interaction and assistive-AI research to describe a mode of user involvement in which the person defers all decisions to the system. In autonomous navigation robots for blind travellers, omakase denotes the…

Robotic Guide Dog(also: Robot Guide Dog, Quadruped Guide Robot)

A mobile robot — typically a quadruped platform — designed to provide navigation and obstacle-avoidance support for blind and low-vision users, filling a role analogous to that of a trained guide dog. Research prototypes have explored handler interaction, leash-based coupling,…

Robotic Social Attributes Scale(also: RoSAS, RoSAS-SF, Robotic Social Attributes Scale Short Form)

A validated psychometric instrument developed by Carpinella et al. (2017) that measures how people perceive the social attributes of a robot along three subscales: Warmth (how likable, friendly, and companionable the robot feels), Competence (how capable, knowledgeable, and…

Social Navigation(also: Socially-aware navigation, Socially compliant robot navigation)

In robotics, the problem of moving through an environment that contains people, in a way that respects social norms, comfort, and safety. Social navigation goes beyond obstacle avoidance: it requires predicting pedestrian intentions, respecting personal space, interpreting…

Social Robot Navigation(also: Socially-aware robot navigation, Social navigation)

A subfield of robotics concerned with how a mobile robot should move through environments shared with humans — choosing paths, speeds, and timings that respect social norms as well as physical obstacle avoidance. Classic robot-navigation algorithms optimise for shortest-path…

Socially Assistive Robot(also: SAR, Social Robot)

A robot designed to assist people through social interaction rather than physical manipulation. Socially assistive robots use embodied presence, movement, and social behaviors such as gaze, gestures, and expressions to provide support in contexts including therapy, education,…

Trouble-Indicating Behavior(also: TIB, Trouble Source-Repair)

Verbal or nonverbal behaviors that signal confusion, misunderstanding, or difficulty in communication. In research on dementia and human-robot interaction, TIBs are categorized into types including: requests for repetition, requests for clarification, metalinguistic comments ("I…
