3 Terms and Definitions
3.1
Under-freshwater search and rescue robots
Special robots with underwater mobile operation capabilities that can enter freshwater areas including lakes, ponds, reservoirs, rivers, canals or disaster-formed freshwater spaces to assist or replace personnel in performing underwater target search or rescue missions.
NOTE: Generally composed of mobile platforms and payloads.
3.2
Mobile platform
The carrier that enables changes in overall attitude (heading, pitch, roll) or position of search and rescue robots.
3.3
Payload
Devices mounted on search and rescue robots to assist in completing underwater target search or rescue missions.
NOTE: Includes search payloads and rescue payloads.
3.4
Search payload
Devices mounted on search and rescue robots for underwater target search.
NOTE: Includes acoustic detection payloads (e.g. sonar), optical detection payloads (e.g. underwater cameras), physicochemical detection payloads and other payloads.
3.5
Rescue payload
Devices mounted on search and rescue robots for underwater rescue.
NOTE: Includes payloads for grasping/movement (manipulators), air delivery, cutting/breaking and other payloads.
3.6
Rated payload
The maximum mass of payload that search and rescue robots can carry along all motion directions under specified speed and acceleration conditions.
3.7
Rated speed
The maximum speed achievable in forward, backward, ascending, descending, lateral movement and turning degrees of freedom under rated payload.
3.8
Three-dimensional maneuverability
The capability of search and rescue robots to perform underwater movements including forward, backward, ascending, descending, lateral movement and turning.
3.9
Current resistance capability
The ability of search and rescue robots to maintain relative stillness and perform target search or rescue missions in underwater current environments.
3.10
Operation control unit
Devices realizing operation and control of search and rescue robots through information interaction between operators and robots.
3.11
Umbilical
Cable assemblies and accessories providing data transmission, power supply and environmental loads for underwater robots.
4 Classification
4.1 By mission type
Search and rescue robots can be classified as:
a) Search type: Robots performing underwater target search with search payloads
b) Rescue type: Robots performing underwater rescue missions with rescue payloads
