Topsky RXR-M2GD (RXR-M2GD)

Topsky RXR-M2GD (RXR-M2GD)

The platform is positioned for fast response—able to “quickly reach the rescue site”—and is intended to begin work immediately after deployment.

In practical emergency-response contexts, robots in this size class are commonly used to reduce human exposure during the earliest phases of an incident by enabling remote observation, basic scene access, and light-to-medium logistics assistance (such as handling equipment and dragging charged hoses), especially when smoke, heat, debris, or uncertain atmospheres may limit safe entry.

Design and Features

Compact, portable chassis for rapid deployment

A defining characteristic of the RXR-M2GD is its portable form factor. The manufacturer listing describes it as “small” and “light,” emphasizing that a single person can carry it.
This design goal typically aligns with scenarios where response teams need robotics support without the delays, transport constraints, or setup time associated with heavier tracked or wheeled firefighting robots.

The published dimensions and weight reinforce its compact positioning:

• Dimensions: 700 mm × 400 mm × 450 mm

• Weight: ≤150 kg

Remote control and video transmission

The RXR-M2GD is marketed with remote control operation and video transmission, supporting stand-off use when direct access is unsafe or visibility is limited.
In modern firefighting robotics, video feedback is central to enabling operators to steer through narrow passages, assess hazards, and coordinate actions with teams operating elsewhere on the incident ground.

Fast approach speed and mobility over obstacles

The RXR-M2GD is described as fast, with the intent of reaching the rescue site quickly. Its published mobility metrics include:

• Maximum linear speed: ≥1.5 m/s

• Climbing ability: ≥70% (or 35°)

• Obstacle crossing height: ≥220 mm

• Wading depth: ≥500 mm

• Straight deviation: ≤0.5%

Collectively, these specifications indicate a design that prioritizes stable driving, slope capability, and practical movement across debris, thresholds, uneven ground, and shallow standing water—conditions that can occur around industrial facilities, construction zones, or damaged structures.

Hose dragging and traction-oriented support

Beyond reconnaissance and access, the RXR-M2GD is listed with substantial pulling capability:

• Traction force: ≥1500 N

• Dragging distance: ≥80 m while dragging 2 DN80 full water hoses

DN80 hoses (especially when charged) can be difficult and time-consuming to advance manually, particularly over rough terrain or around obstacles. A compact robot capable of dragging charged lines can support hose positioning while limiting fatigue and exposure for responders.

Quick “open and leave” operation concept

The RXR-M2GD listing notes that “the cart can be opened and left immediately after operation,” suggesting a workflow built around rapid staging and retrieval, rather than extended setup.
For emergency teams, this kind of operational simplicity is often a key requirement: equipment needs to be deployable under stress, in low visibility, and with minimal steps.

Technology and Specifications

Core published specifications

The primary published specifications for the Topsky RXR-M2GD include:

• Dimensions: 700 × 400 × 450 mm

• Weight: ≤150 kg

• Traction force: ≥1500 N

• Dragging distance: ≥80 m (2 × DN80 full water hoses)

• Maximum linear speed: ≥1.5 m/s

• Straight deviation: ≤0.5%

• Climbing ability: ≥70% or 35°

• Obstacle crossing height: ≥220 mm

• Wading depth: ≥500 mm

• Brand: TOPSKY; Part #: RXR-M2GD; Origin: China

Because publicly listed specifications may differ by configuration, buyers typically confirm the final version (battery type, control range, camera setup, environmental rating, etc.) as part of procurement.

Applications and Use Cases

Rapid reconnaissance in early incident phases

The RXR-M2GD’s portability and remote video operation make it suitable for early-phase scene assessment, where responders need quick visual confirmation of conditions without committing personnel into a potentially unsafe zone.
This can include checking access paths, identifying obstructions, and verifying whether hose advancement routes are viable.

Hose advancement support and logistics assistance

With a stated ability to drag two DN80 full water hoses for ≥80 meters, RXR-M2GD is positioned as a practical tool for hose handling support, particularly when lines must be moved over rough terrain or toward a hot zone.
This role is especially valuable when manpower is limited, when exposure time must be minimized, or when the working surface is slippery or unstable.

Operation in wet, debris-heavy, or uneven environments

The combination of obstacle-crossing height (≥220 mm), climbing ability (35°), and wading depth (≥500 mm) supports deployments where water runoff, broken terrain, thresholds, and debris are present.
These constraints are common in industrial yards, ports, tunnels, and damaged structures—places where rapid robotic access may help establish safer operational footing.

Advantages / Benefits

Improved responder safety through stand-off operation

Remote control and video transmission allow teams to operate the robot at a distance, reducing exposure when conditions are uncertain or deteriorating.

High mobility in a compact package

Despite its small footprint, RXR-M2GD lists meaningful mobility figures (≥1.5 m/s speed, 35° climbing, and 500 mm wading depth), supporting real-world maneuvering where conventional equipment may be slowed.

Practical hose logistics capability

DN80 hose dragging for ≥80 meters is a direct operational benefit, addressing a common bottleneck during incident escalation—advancing lines quickly while limiting fatigue and time in hazard zones.

Deployability and simplified field workflow

The “one person can carry” positioning and the immediate-use deployment concept are advantages for response teams that need equipment to be staged quickly and moved between locations without heavy transport.
