Heavy Duty Tracked Robot Chassis

A large tracked robot chassis is a mobile robot platform centered on tracks (also known as a tracked walking mechanism), primarily used in industrial or specialized robots. It provides a large support area and traction through continuous contact with the ground via tracks, making it suitable for movement in complex terrain.

High all-terrain adaptability: The heavy duty tracked robot chassis has a larger ground contact area, effectively distributing weight and reducing ground pressure. This enables it to travel smoothly on soft or uneven terrain such as sand, mud, snow, and gravel, without slipping or getting stuck.

Outstanding obstacle-crossing capability: Tracks can traverse steps, gullies, and obstacles, providing higher mobility in harsh environments.

Stable heavy-load capability: The large contact area between the tracks and the ground provides better friction, lowering the robot's center of gravity. This allows the robot to maintain good stability even when carrying heavy loads or moving over rugged terrain, reducing the risk of overturning. Therefore, it is commonly used in applications requiring high load-bearing capacity, such as bomb disposal, firefighting, reconnaissance, and transportation.

On-the-spot turning capability: The large tracked chassis can achieve 360-degree turning on the spot by controlling the speed and direction of the tracks on both sides. This small turning radius allows the robot to adjust its direction flexibly in confined spaces, enhancing its maneuverability.

In the field of firefighting, it is used for reconnaissance and rescue in dangerous areas such as fire scenes and earthquake rubble. Equipped with a remote-controlled water cannon and foam mixture spray device, it is suitable for firefighting operations in petrochemical plants and underground structures. The post-disaster rescue model is equipped with a foldable track platform and mechanical arm, enabling it to traverse rubble to perform life detection.

Exploration and scientific research: Used for geological exploration, polar scientific research, deep-sea exploration, and other applications, capable of operating in remote environments.

In chemical scenarios, explosion-proof models are equipped with gas modules and thermal imaging cameras to monitor combustible gas leaks and high-temperature hazards in real time.

During tunnel collapse rescues, robots transmit real-time imagery from reconnaissance cameras to guide the development of rescue plans.

The choice between a heavy duty tracked chassis and a wheeled chassis primarily depends on the robot's specific application environment and task requirements. If the robot needs to operate in complex, rugged terrain and speed and turning flexibility are not critical, a large tracked chassis is the better choice.

1. Where will the robot primarily operate?  

(1) Over 90% on flat, hard surfaces (indoor/urban roads)?  

Prefer wheeled.  

(2) Frequently in complex terrains such as mud, sand, snow, large rocks, thick grass, or rubble?  

Prefer tracked.

2. What are the most critical requirements?

(1) Speed, range, low cost, low maintenance, quiet operation?

Prefer wheeled (consider large wheel diameter/good tires/suspension).

(2) Absolute reliability in terrain traversal, no getting stuck, strong climbing ability, high load capacity?

Prefer tracked.

(3) Turning on the spot in narrow spaces?

Tracked has an advantage, but wheeled omnidirectional wheels have a greater advantage on flat surfaces.
