Over the last few decades, quadruped robots have experienced significant growth, stimulated by an increasing demand for mobile robots capable of exploring environments deemed too risky for humans. Compared with other mobile robots, robot dogs stand out for their adaptability, stability, and manoeuvrability. Quadruped robots are particularly well-suited to an urban environment designed for humans:
- They can go up and down stairs
- Equipped with an arm, they can open doors fitted with door closers
- These robots can easily manoeuvre in tight spaces where the ground is neither flat nor smooth (water supply or drainage pipes) underground galleries, etc)
Currently, two major brands share a significant portion of the dog robot market: Boston Dynamics and Deep Robotics. In this article, we present the different models available, their advantages and their varied applications.

Spot, the robot that cuts your costs
- Reduce time spent by operators on manual data collection
- Detect faults before they cause on-site operations to grind to a halt
- Compensate for lack of manpower
- Prevent operators from finding themselves in risky situations
- Reallocate teams to high value-added activities: analysis, decision-making
- Carry out investigations remotely and securely
Price
Cost may vary according to specific configurations and additional services. The Spot robot is generally considered a high-end solution and its price can be significant. However, its performance, versatility, and long term benefits justify the investment. In time, users find that the return on investment and the operational benefits far outweigh the initial purchase price.
Ready to use business packs
Spot Academia & Education
Designed for research, education, and the development of new applications, the “package” features ready-to-use functions, opening up vast possibilities in the field of robotics.
Developers can exploit its autonomous capabilities, while the Spot Arm enables advanced interaction with the environment.
Spot is fully customizable and is an advanced tool for preparing students for the future of robotics
Spot Public Safety
The Spot State & Public Safety pack offers a robust solution for reducing risks in potentially hazardous environments.
Indeed, Spot can investigate suspicious packages, assist in hostage situations by providing crucial remote information, and detect various hazardous materials such as toxic substances and explosives.
Equipped with cameras, X-ray devices, and a robotic arm, Spot enables secure intervention by first responders while maintaining a safe distance.
Spot Inspection
The Spot Enterprise Asset Management Kit automates inspection tasks, providing accurate real-time data to fuel predictive maintenance.
Equipped with multiple payloads, Spot can perform thermal inspections to detect anomalies in equipment, read and analyse analogue gauges, and even conduct acoustic inspections to identify leaks in ducts.
This kit enables the proactive collection of essential data to optimise industrial asset management.
The latest news
Boston Dynamics has just launched Orbit, a robot fleet management software offering real-time control and data analysis to improve operational efficiency. Orbit lets you plan and track missions, receive personalised alerts, and operate robots remotely.
X30 from Deep Robotics: a robust robot for Research and Development
Specifications
Key benefits
- IP67: can be fully immersed in water, even with the PC
- Autonomous navigation and mapping + video feedback from joystick
- PC with RTK antenna and 5G module: can be remotely operated over very long distances
- Emergency stop function
- Interchangeable battery, essential for emergency interventions
- Compatible with Kinova arms
Applications
X30 can be used for inspection, search and rescue missions.
Price
The X30 robot dog is also considered a high-end option. Its price is more affordable than that of Spot, making it potentially more accessible for certain markets. However, it is essential to note that the Spot performs better when it comes to obstacle avoidance.
Lite 3 from Deep Robotics: an affordable robot for research and development
Technical specifications
Key benefits
- Use of intelligent algorithms, such as reinforcement learning
- Can be developed into a real solution (not limited to research and development)
- With BOW license, all programming languages can be used
- Joystick with integrated video feedback
- Autonomous navigation and people tracking possible from the joystick

5 Reasons to choose a robot dog over a mobile robot on wheels
1) Obstacle-clearing capability
Thanks to their four-legged configuration, quadruped robots can, for example, climb stairs, which can be essential in inspection or rescue situations.
2) Indoor & Outdoor
Unlike mobile robots, which generally operate indoors or outdoors, quadruped robots have the advantage of combining both, making them multitask and, above all, multi-terrain.
3) Integrated sensors
Quadruped robots have built-in cameras and sometimes even a 4D LiDAR, as in the Go2 robot from Unitree Robotics.
4) Manoeuvrability in confined spaces
Their agility and ability to move in confined spaces make quadruped robots a wise choice for applications where space is limited. For example, SNCF called Generation Robots in March 2022 for inspection missions on a 2-level Transilien train. Read our blog article on this subject.
5) Adaptability to varied terrain
Thanks to their ability to climb and jump, quadruped robots are often more versatile than wheeled robots. They can navigate efficiently over rough, uneven, or cluttered terrain that might be difficult for wheeled robots to access.
