Trottoirrobots

Trottoirrobots are autonomous or semi-autonomous robots designed to operate on urban sidewalks. The term, blending trottoir (French for sidewalk) with robots, is used in international discussions of urban automation to describe a class of small, pedestrian-area machines tasked with service-oriented functions in public spaces, particularly on or near pedestrian corridors.

Design and capabilities usually emphasize safety and coexistence with people. Common form factors are compact wheeled or tracked units capable of low-speed travel, with audible and visual indicators to signal their presence. Core technologies include sensors such as cameras, lidar or radar, inertial measurement units, and sometimes GPS-denied localization, along with obstacle avoidance, mapping and path-planning software. Energy typically comes from rechargeable batteries, and many trottoirrobots rely on edge computing or cloud services to process tasks.

Operations and use cases vary by jurisdiction but commonly include last-mile delivery of small parcels or meals, mobile information or wayfinding kiosks, street-cleaning and sanitation, and public-service demonstrations. Some models are designed to operate within defined sidewalks, crosswalks, or dedicated pedestrian lanes, while others are permitted to share wider pedestrian zones under specific safety rules and supervision.

Regulation and social aspects are central to their deployment. Questions of pedestrian safety, privacy, accessibility, and the impact on work in local services drive pilot programs and policy discussions. Compliance often involves permits, insurance, geofencing, speed limits, and interaction protocols with pedestrians.

Status and outlook are developmental: trottoirrobots are increasingly demonstrated in pilot projects, but standards, governance, and broad-scale adoption remain evolving as cities balance innovation with public safety and urban livability.
