Types of tank tracks for robots

Robotic tank tracks are designed to help robots traverse uneven terrain and surfaces smoothly. The following types of tank tracks for robots are used in various industries, including military, surveillance, search and rescue, remote exploration, and industrial inspection.

• Rubber Tracks

  Rubber tracks for tanks are track systems made of elastic materials, usually rubber. Over the past few years, they have become one of the most popular tank track systems for robots. They are comfortable and gentle to use, and they behave well in various conditions. Robots outfitted with rubber tracks may easily navigate rugged terrain, steep slopes, and obstacles. They provide robots with excellent stability and a uniform movement pattern. This ensures that fragile control systems and sensitive instruments are not disrupted. There are two ways to produce rubber tracks for tank robots; they can be made of solid rubber or comprise a flexible material reinforced with metal or fiber threads.

• Modular Plastic Links

  Modular plastic blogs are made up of many detachable sections that are often made of plastic. They are also manufactured using lightweight materials or composites. This makes them a good option for robots whose weight has to be kept down to improve battery life. Modular plastic links offer robust and adaptable movement patterns. This enables them to travel through rough terrain rapidly and with ease. Plastic links assembled together offer remarkable versatility. They permit custom design and rapid replacement of damaged components.

• Metal Tracks

  Metal tracks are tank track systems made of solid metal or metal plates. They are a common feature of large tanks and armored vehicles. Metal tracks for robots offer strength, robustness, and longevity. They enable robots to cope easily with heavy loads and tough environmental conditions.

Specification and Maintenance

Robot tank track typically consists of six parts, as shown in the following table.

• Chassis

  The chassis is the main body of the robot, which supports the other components and provides a space for installation and connection. The chassis also helps form the overall structure and shape of the robot.

• Drive Motor

  The drive motor (usually a DC motor or stepper motor) provides the driving force for the movement of the robot. The motor converts electrical energy into mechanical energy, driving the tank track to rotate.

• Rotary Encoder

  The rotary encoder is a sensor attached to the drive motor. It is responsible for measuring the rotation speed and direction of the motor, thus feeding back the moving speed and posture of the robot to the controller. This information allows the controller to make precise control decisions to ensure the robot moves as desired.

• Controller

  The controller (usually a single-chip microcomputer or a single-board computer) acts as the brain of the robot. It is responsible for issuing instructions to control the rotation direction and speed of the drive motor based on the inputs from various sensors. Additionally, the controller processes data from the rotary encoder to adjust the robot's movement in real-time.

• Power Supply

  The power supply (such as a battery pack) provides the necessary electrical energy for the robot's operation. It powers the drive motor, controller, sensors, and other components, ensuring the robot can move and function properly.

• Sensor (Optional)

  Sensors can include distance sensors, gyroscopes, accelerometers, and more. These sensors are responsible for gathering information about the robot's surroundings and its own status, such as obstacle distances, orientation changes, and acceleration. This information can be sent to the controller for more intelligent control of the robot's movement.

To ensure their longevity and proper functioning, it is vital to maintain tank tracks for robots. The following are some maintenance suggestions:

• Frequent cleaning:

  It is crucial to maintain the cleanliness of the tank track after each usage. Remove any dirt, dust, or debris with clean water and mild detergent, and let them dry naturally. This can prevent dirt from accumulating and compromising performance.

• Lubrication:

  Regular lubrication is critical for maintaining the smooth movement and optimal functioning of tank tracks. Apply appropriate lubricants to the moving parts, such as the track's rollers and gears, ensuring uniform and smooth lubrication. This can reduce friction and wear, prolonging the tank track's lifespan.

• Avoid overload operation:

  Operating beyond the load capacity can expedite the wear and tear of tank tracks. Adhere to the manufacturer's prescribed load capacities to prevent overloading, thereby preserving the longevity of the tracks.

Scenarios

Tank tracks for robots are used in different scenarios. Here are some of them:

• Industrial automation: Tank tracked robots are used in an industry setup with different floor types. The tracks allow the robot to move easily, even if the terrain is irregular or abrasive. This helps the robot carry out its tasks of material movement, assembly, or inspection.
• Construction and demolition: Tank tracked robots are useful in construction and demolition tasks. They can easily navigate rough terrain and obstacles found in outdoor and worksite environments. This allows them to do heavy-duty tasks like material transportation, site mapping, and remote monitoring.
• Search and rescue: In search and rescue situations, tank tracked robots are sent into hazardous terrains. They are able to go through difficult landscapes (like debris, mud, and rough terrain) to access areas that are hard to reach by humans. They can be used for monitoring, delivering supplies, or locating victims.

How to choose tank tracks for robots

There are multiple types of tank tracks available in the market. When considering buying them for their robots, buyers should carefully analyze the factors that will affect their robot's performance.

• Robot's Weight and Payload

  Heavy robots will need larger and softer tank tracks. They will need to have a wide surface area and low ground pressure to ensure that the robot moves smoothly without damaging the tracked system.

• Terrain

  The terrain where the robot will move should also be considered. For rugged terrain with obstacles like sand, gravel, and mud, rough terrain tracks for robots with larger and deeper treads should be picked. Smooth tracks with less tread can be used for robots that will move on smooth and even surfaces.

• Speed and Agility

  Buyers should consider the kind of robot movement they want to achieve. If a robot needs to have fast speed and agility, then purchasing rubber tank treads for robots with softer materials should be considered. However, if the robot needs to have high acceleration and top speed, then a tracked system with less tread and lighter than normal can be used.

• Environmental Considerations

  Environmental factors such as temperature, humidity, and exposure to chemicals should also be considered. Buyers operating robots in extreme temperature environments should consider tracks made of materials resistant to temperature extremes, like silicone tracks for robots.

• Motor and Gearbox Compatibility

  When choosing tank tracks, buyers should consider if the gearbox and motor that are driving the track system are well compatible with it. This will ensure smooth movement and sufficient power transmission.

Tank tracks for robots Q&A

Q1: What material is commonly used for tank tracks?

A1: Modern tank tracks are made with polymer (rubber) or metal. Polymer tracks are quieter and more comfortable on rough terrain, while metal tracks are tougher and better for handling heavy weights.

Q2: What size of tank track is suitable for a robot?

A2: The size of the tank track depends on the weight and dimensions of the robot. A small robot weighing 10 kg or less can use a tank track with a wheel diameter of 5 to 10 cm. For bigger robots, the diameter of the tank wheel should be 20 cm or more.

Q3: How do tank tracks get power?

A3: Each drive wheel has an electric motor fixed directly to it. In some robot designs, the motors driving the tank tracks are connected to the chassis through a transmission system, which allows the transmission of power from different types of engines.

Q4: How does the robot with tank tracks move?

A4: The robot moves by rolling the tank drives and by applying force on the ground from the chassis connected to the tank drives. The friction between the tank track and the ground enables the robot to move.
