ARI

ARI is a social humanoid robot developed by PAL Robotics (Barcelona, Spain) standing 165 cm tall and weighing 50–60 kg. Designed for human-robot interaction in healthcare, retail, and research environments, it features dual arms, face recognition, multilingual voice support, and semi-autonomous navigation capabilities.

Overview and Use Cases

ARI is a social humanoid robot developed by PAL Robotics for deployment in human-centric environments. The robot is intended for roles including hospital assistance, retail service, information kiosks, and research applications. It has been commercially available since approximately 2018–2019 and received upgrades showcased at CES 2026.

Key Capabilities

  • Human-Robot Interaction: Face recognition and 3D skeleton tracking for social engagement
  • Voice and Language: Voice activity detection with support for 30+ languages
  • Navigation: RFID-capable autonomous navigation on wheeled differential-drive base; semi-autonomous operation within supervised or configured contexts
  • Manipulation: Dual arms capable of light manipulation and expressive gesturing
  • Perception: Integrated sensors for environment awareness and human detection

Specifications

  • Height: 165 cm
  • Weight: 50–60 kg
  • Degrees of Freedom: 20 DOF total; 5 DOF per arm
  • Arm Payload Capacity: 0.5 kg per arm
  • Mobility: Differential-drive wheeled base; maximum speed 1.5 m/s on flat surfaces
  • Battery Runtime: 8–12 hours

Applications

ARI has been deployed across multiple domains:

  • Healthcare Settings: Hospital assistance and patient interaction roles
  • Retail Environments: Customer-facing service and information provision
  • Research Platforms: Used as a foundation for research frameworks and autonomous systems studies
  • Agricultural Monitoring: Integration into monitoring and data collection systems
  • Academic Research: Deployed by multiple research groups for human-robot interaction studies

The robot serves as both a commercial service platform and a research-accessible platform for developers and institutions exploring social robotics and autonomous systems.

Relay Delivery RobotRobot

Relay Delivery Robot

The Relay Delivery Robot is an autonomous indoor delivery robot developed by Relay Robotics (formerly known as Savioke), designed primarily for hospitality and healthcare environments. It navigates hotel corridors and hospital hallways independently, rides elevators without human assistance, and delivers guest amenities, medications, linens, and other supplies directly to rooms or designated drop-off points. Relay is one of the most widely deployed service robots in its category, reportedly completing over one million lifetime deliveries with a publicly cited success rate of approximately 99.8%. With a cargo capacity of around 10 gallons, the robot is compact enough to operate in busy public spaces while carrying a meaningful payload of everyday supplies.

Spot

Spot is a four-legged autonomous robot developed by Boston Dynamics, a robotics company headquartered in Waltham, Massachusetts. Designed for inspection, security, and data collection in complex or hazardous environments, Spot can navigate stairs, rough terrain, and confined spaces that are inaccessible to wheeled robots. It is commercially available and has been deployed across industries including utilities, oil and gas, construction, and public safety. Spot supports a modular payload system that accommodates thermal cameras, pan-tilt-zoom (PTZ) cameras, lidar units, methane sensors, and other mission-specific hardware. Boston Dynamics also offers the Orbit fleet-management software platform, enabling operators to schedule autonomous inspection routes, aggregate sensor data, and manage multiple Spot units from a central interface. The robot is widely regarded as one of the most capable and commercially mature legged robots on the market.

RealSense Depth Camera D455Robot

RealSense Depth Camera D455

The RealSense Depth Camera D455 is a stereoscopic active-infrared depth camera belonging to Intel's D400 series, designed to capture high-fidelity depth data for robotics, autonomous mobile robots (AMRs), drones, and computer-vision applications. It features a 95 mm stereo baseline — the widest in the D400 lineup at the time of its introduction — which reportedly enables depth error of under 2% at ranges up to approximately 4 metres. Originally developed under the Intel RealSense brand, the D455 and related products were later spun off as part of an independent RealSense business unit following Intel's restructuring of the division around 2021–2022. The camera is widely adopted in research, industrial automation, and humanoid-robot development owing to its compact USB-powered form factor, open SDK support, and relatively accessible price point.
