One-stop AMR building solution｜How to choose the most suitable mobile robot motion model？

In the process of #manufacturing mobile #robots, it is particularly critical to select the most appropriate #motion #model according to the actual application scenarios and task requirements, which is also an important link to build efficient mobile robots.

The selection of the most appropriate motion model requires comprehensive consideration of multiple factors, such as terrain, ground conditions, space constraints and other scene environments, as well as robot load requirements and work intensity.

In the partner model library of SEER Robotics, the more common motion models of industrial mobile robots include: Double-wheel-drive differential、Four-wheel-drive differential、Four-differential module、All-wheel-drive Mecanum wheel、Single steering wheel、Double steering wheel、Four steering wheel、Tracks, etc.

Double-wheel-drive differential

The Double-wheel-drive differential motion model is mainly composed of the driving wheel and the following wheel, and the differential between the two makes the robot adjust the rotation speed of the wheel according to the different steering angle when it turns, so as to achieve stable steering.

Double-wheel-drive differential has the characteristics of high flexibility, simple structure, low cost and easy maintenance, which is more advantageous in narrow space and complex terrain, and can be applied to the scenes with high ground flatness, small load, and low requirements on motor and control accuracy.

Four-wheel-drive differential

The four-wheel-drive differential motion model adds two wheels on the basis of the double-wheel-drive differential, and four wheels can be driven independently. When the robot turns, it can control the rotation speed of the wheels to achieve more accurate steering and obstacle avoidance.

Four-wheel-drive differential has stronger power and better stability and carrying capacity, the wheel can be upgraded to a larger size, easily over the ground potholes, and is not afraid of complex terrain, which can be applied to scenes with higher bearing capacity and pass ability requirements.

Four-differential module

The four-differential module consists of four differential wheel groups that support omnidirectional motion. Compared with four-wheel-drive differential, four-differential module can better adjust the speed of each wheel during steering, thus improving the robot's maneuverability, and can be applied to scenes with high maneuverability requirements.

All-wheel-drive Mecanum wheel

The all-wheel-drive #Mecanum wheel motion model is composed of four Mecanum wheels with a number of small wheels on the rim, so that the wheel can still achieve forward, backward, left and right all-direction movement in complex terrain without changing the direction.

All-wheel-drive Mecanum wheel has the characteristics of fast movement, high stability, high flexibility and strong bearing capacity. It can support the load of 10T or more, but the overall cost is higher and the structure is more complex, and it can be applied to the scene that requires high moving speed and flexibility.

Single steering wheel

The single steering wheel sports model is equipped with a steering wheel, which can realize the steering of the robot by changing the steering angle.

The Single steering wheel is based on single wheel drive, so there is no need to consider the coordination of the drive motor, the structure is simpler, the cost is lower, but the overall flexibility is poor, more suitable for fast movement and accurate positioning on flat ground, can be applied to the steering accuracy requirements are not high, the ground requirements are relatively low scene.

Double steering wheel

The Double steering wheel motion model adds a steering wheel on the basis of the single steering wheel, which can achieve more accurate control during steering, improve the robot's mobility and flexibility, and support the front and back left and right omnidirectional movement.

The overall manufacturing cost of the double steering wheel is higher, and the requirements for ground smoothness are more stringent, which can be applied to scenarios with high mobility requirements and large load handling.

Four steering wheel

The four #steering #wheel motion model is composed of four steering wheels for more accurate steering and obstacle avoidance, as well as greater load carrying capacity and power. It also has high machine flexibility and stability, and can still maintain stable operation in complex environments, and can be applied to scenes with high requirements for flexibility and steering accuracy.

Tracks

The #tracks motion?model uses tracks as a moving device and can adapt to a variety of complex terrain. Tracks has high carrying capacity, portability, and stability, and is suitable for outdoor scenarios that require high terrain adaptability and high load.

Fully consider the application scenario, operation requirements and other multi-dimensional factors, select the most appropriate mobile robot motion model, not only to ensure the stable operation and efficient operation of mobile robots, but also to reduce costs and increase efficiency for customers to the greatest extent.
