Technological Backbone: Enabling Precision and Safety in Confined Spaces
The seamless operation of slim-profile delivery robots in narrow environments relies on cutting-edge navigation, obstacle avoidance, and control technologies. These systems ensure that the robots can navigate complex, dynamic spaces with centimeter-level precision, avoiding collisions and optimizing routes—critical capabilities for confined-area operations.
Navigation technology is a cornerstone of their performance. Most models integrate SLAM (Simultaneous Localization and Mapping) and visual positioning systems to achieve accurate navigation without the need for QR code stickers, preserving the integrity of the operating environment while reducing deployment costs . The T10 robot combines SLAM with Vslam intelligent positioning, using top visual sensors to identify environmental features and realize centimeter-level positioning, significantly improving deployment efficiency . For warehouse robots like KARLSTADT’s VFR series, multi-modal positioning (laser radar 3D camera) ensures stable operation even in environments with frequent changes in stack positions and personnel movement, reducing positioning errors to near zero .
Safety and obstacle avoidance are equally paramount in narrow spaces. A 360° panoramic perception system, integrating laser radar, 3D cameras, and RGB sensors, provides comprehensive environmental awareness. The T10 robot is equipped with 4 stereo vision sensors, 1 laser radar, and 1 RGB camera, covering a 300° dynamic obstacle detection range to accurately distinguish between humans and objects and prevent collisions or foot crushing . The Leopard Slim employs autonomous driving-level visual navigation to adjust speed intelligently and avoid guests proactively, while its automatic smart password lock ensures the privacy and safety of delivered items . For high-altitude warehouse operations, KARLSTADT’s VFR-CS1 uses a "three-eye" recognition system (dual 3D cameras laser radar) to achieve ground picking of field-shaped pallets and trigger emergency stops within 0.3 seconds if high-altitude obstacles are detected .
Intelligent scheduling systems further amplify efficiency in multi-robot operations. Reeman’s proprietary autonomous dispatch system supports multi-point delivery tasks, automatically planning optimal routes and avoiding congestion among multiple robots . KARLSTADT’s VFR series adopts a "large and small vehicle collaboration" solution, where high-lift robots handle upper shelf operations and slim robots manage low-level access, creating a seamless, efficient warehouse workflow .

In the catering and hospitality industry, these robots have become mainstream solutions for indoor delivery. The T10 robot serves in restaurants, hotels, and gyms, delivering meals, beverages, and supplies with stable performance—its shock absorption system ensures drinks remain spill-proof even on rough surfaces . The Leopard Slim excels in hotels, integrating with cloud management platforms for one-click control and supporting takeout order connection, where riders scan a QR code to link room numbers for seamless delivery . Its 15° ergonomic angle design and customizable appearance stickers allow it to blend naturally into hotel environments while enhancing guest interaction.
Warehousing and logistics benefit most from the space-saving capabilities of these robots. KARLSTADT’s VFR series has redefined high-density storage by reducing aisle width from the traditional 2.5m to 1.65m, boosting space utilization from less than 50% to over 70% . The VFR-CC model, nicknamed "Giant Spirit God," achieves a lifting height of 6.8m and maintains a 1-ton load at 5m, perfectly meeting the heavy-load needs of high-rise warehouses . Tarqan’s robot increases picking efficiency by 300% compared to manual labor, handling 400-500 products per hour with 99.99% accuracy, significantly reducing order delays and errors .
Beyond these core sectors, the robots are expanding into community delivery, healthcare, and manufacturing. Yuefan Innovation’s Xiangdi Ultra realizes seamless indoor-outdoor operation, serving as a mobile service node connecting community buildings and meeting multi-point delivery needs . In healthcare settings, their slim profiles allow navigation through crowded hospital corridors to deliver medications and supplies, reducing cross-contamination risks through contactless delivery.
