Lite3
The Lite3 is a quadruped robot dog manufactured by Deep Robotics, designed for research, education, and entertainment applications. Introduced at ICRA 2023, it is available in four variants with prices ranging from approximately $2,890 to $5,400 USD, featuring modular design, ROS/ROS 2 support, and optional autonomous navigation capabilities.
Overview and Use Cases
The Lite3 is a quadruped robotic platform developed by Deep Robotics as an educational and research-oriented alternative to the manufacturer's industrial inspection systems. The robot was publicly debuted at the International Conference on Robotics and Automation (ICRA) 2023 in London. It is intended for use in research institutions, educational settings, and hobbyist applications requiring a mobile robotic platform with modular expansion capabilities.
Key Capabilities
The Lite3 supports multiple control and autonomy modes depending on variant selection:
- Robot Operating System (ROS/ROS 2) compatibility for integration with standard robotic development environments
- Software Development Kit (SDK) and API access for custom application development
- Modular expansion framework allowing attachment of sensors and payloads
- Teleoperated control available on all variants
- Autonomous navigation and obstacle avoidance on higher-end variants equipped with LiDAR sensors
- Payload capacity of up to 7.5 kg depending on configuration, with the Basic variant supporting 5 kg
Specifications
Physical Dimensions:
- Standing height (Basic/lower variants): 610 × 370 × 406 mm
- Standing height (higher variants with sensor mast): 610 × 370 × 496 mm
- Weight: 12 kg (Basic variant) to 13.7 kg (Pro LiDAR 2 variant), including battery
- Stair/step climbing capability: 15–18 cm step height
Performance:
- Battery life: 1.5–2 hours per charge
- Operating range: 2.7–5 km depending on variant (Basic: 5 km; Venture: 4 km; Pro: 3.4 km; Pro LiDAR 2: 2.7 km)
Pricing:
- Price range: Approximately $2,890–$5,400 USD depending on variant and retailer
Product Variants
The Lite3 is offered in four configurations:
- Basic: Entry-level variant with teleoperated control, 5 kg payload capacity
- Venture: Mid-range variant with enhanced capabilities
- Pro: Advanced variant with improved sensors and performance
- Pro LiDAR 2: Highest-specification variant including LiDAR-based autonomous navigation and obstacle avoidance
Each variant maintains the same general quadruped form factor while differing in sensor packages, autonomy features, and operational range.

RobotRelay 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.

RobotSpot
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.

RobotRealSense 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.
