Shenzhen Alu Rapid Prototype Precision Co., Ltd.

The working principle of a robot chassis depends on its design and the robot’s purpose (e.g., wheeled, legged, or stationary robots). Here’s a breakdown of how it operates, focusing on a typical mobile robot chassis (e.g., a wheeled robot):

Design and Material:

The chassis is designed to be rigid yet lightweight, often made from materials like aluminum, steel, or reinforced plastics (e.g., ABS or carbon fiber). Companies like Shenzhen Alu Rapid Prototype Precision Co., Ltd. use CNC machining or 3D printing to create precision chassis tailored to specific requirements.

The design accounts for the robot’s size, weight, and intended environment (e.g., smooth surfaces, rough terrain, or industrial settings).

Locomotion System Integration:

For wheeled robots, the chassis mounts motors (e.g., DC or servo motors) connected to wheels or tracks. The motors receive power and signals from the control system to drive movement.

For legged robots, the chassis supports articulated joints and actuators (e.g., servos or hydraulics) for walking or climbing.

The chassis ensures proper alignment and weight distribution to prevent tipping or instability during motion.

Power and Control Integration:

The chassis houses the power supply (e.g., lithium-ion batteries) and control electronics (e.g., microcontroller or onboard computer).

Wiring channels or compartments within the chassis route power and data to sensors, actuators, and communication modules, ensuring seamless operation.

The control system processes sensor inputs (e.g., from ultrasonic sensors or cameras mounted on the chassis) to navigate obstacles or follow paths.

Stability and Balance:

The chassis is designed with a low center of gravity to enhance stability, especially for mobile robots. For example, a wider wheelbase or strategically placed weights prevents tipping during high-speed turns or on uneven terrain.

In legged robots, the chassis may include gyroscopes or accelerometers to maintain balance, with the control system adjusting actuator positions dynamically.

Environmental Adaptability:

The chassis may incorporate features like shock absorbers, sealed compartments, or corrosion-resistant coatings to operate in challenging environments (e.g., outdoor, industrial, or underwater settings).

For example, a chassis for a warehouse robot might have reinforced wheels for heavy loads, while a drone chassis prioritizes lightweight materials for flight efficiency.
