xArm 850
The xArm 850 is a 6-axis collaborative robot arm manufactured by UFACTORY with an 850 mm reach and 5 kg payload capacity. Designed for educational, research, and light manufacturing applications, it features ±0.02 mm repeatability and supports multiple programming interfaces including Python, C++, ROS, and UFACTORY Studio.
Overview and Use Cases
The xArm 850 is a six-degree-of-freedom collaborative manipulator developed by UFACTORY for educational institutions, research and development laboratories, and light manufacturing environments. The robot is positioned as a cost-competitive alternative to industrial-grade collaborative arms, with retail pricing in the $9,849–$10,499 USD range.
Key Capabilities
- Reach: 850 mm workspace radius
- Payload: 5 kg maximum lifting capacity
- Repeatability: ±0.02 mm positional accuracy
- Maximum Speed: 1 m/s
- Degrees of Freedom: 6 axes
- Weight: 17 kg (37.5 lb)
- Construction: Aluminium and carbon fiber materials
Specifications
The xArm 850 is a compact, lightweight manipulator designed for tabletop and bench-mounted deployment. Its relatively low weight and modest payload capacity position it for precision tasks requiring fine control rather than heavy-load applications.
Programming and Control
The arm supports multiple control and programming interfaces:
- UFACTORY Studio graphical user interface
- Python scripting
- C++ development
- ROS (Robot Operating System) and ROS2 integration
Users can program the arm to execute autonomous tasks without requiring on-site technical support. Task autonomy depends entirely on user-defined programming; the system does not perform autonomous operations out-of-box.
Applications
The xArm 850 is applicable to:
- Educational robotics instruction and training
- Research and development projects
- Laboratory automation tasks
- Precision assembly operations
- Light manufacturing processes
The combination of programmability, compact form factor, and moderate cost makes it suitable for institutional and small-scale commercial settings where flexibility and accessibility are prioritized over high payload capacity or speed.

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.
