Analysis on the integration of cattle and sheep breeding robots and wireless charging technology

Against the backdrop of the increasing scale and intelligence of modern animal husbandry, cattle and sheep farms are gradually introducing automated and intelligent equipment to reduce labor costs and improve operational efficiency. As one of the representative equipment, cattle and sheep breeding robots usually perform key tasks such as feeding management, health monitoring, behavior recognition, manure cleaning, and environmental data collection. However, how to ensure the continuous energy supply of robots during long-term, high-frequency operations is a core issue that affects system reliability and efficiency. Wireless charging technology is becoming a key infrastructure to achieve "unmanned operation and maintenance".

1. Core functions of cattle and sheep breeding robots

Cattle and sheep breeding robots generally have the following capabilities:

1. Smart feeding: According to the set feed formula, quantitative, fixed-point, and timed feeding can be achieved to reduce feed waste.
2. health monitoring: Use cameras, infrared sensors, body surface temperature detection and other means to monitor the health status of cattle and sheep.
3. behavioral analysis: Identify eating duration, exercise status, abnormal lying down and other behaviors to support disease early warning.
4. Manure removal and ground maintenance: Keep the cowshed clean and reduce the risk of germs.
5. Environmental monitoring: Collect data such as temperature, humidity, and ammonia concentration to provide a basis for precise breeding.

These functions require the robot to have the ability to operate continuously and stably for a long time, so the flexibility and reliability of the power supply mode are crucial.

2. Advantages of wireless charging in animal husbandry application scenarios

The application of wireless charging in environments such as cattle and sheep farms has significant advantages:

1. No need for manual plugging and unplugging, reducing labor maintenance costs
   Traditional charging methods rely on manual operation and are susceptible to impacts from cattle and sheep, humid environments, dust, etc. Wireless charging is fully automated and more suitable for unmanned farms.
2. Dust-proof, moisture-proof, corrosion-proof, adaptable to animal husbandry environment
   The charging device adopts a sealed structure without exposing the metal contact surface, which can effectively avoid the influence of feces, water vapor and corrosive substances.
3. Support 7×24 hours autonomous return charging
   The robot can automatically return to the wireless charging area between tasks or when the battery is too low to achieve uninterrupted operation.
4. Adapt to typical power requirements of mobile robots
   Current wireless charging technology can cover the range of 200 W to tens of kW to meet the power requirements of cattle and sheep breeding robots of different specifications (ground inspection type or large-scale feeding type).

3. Wireless charging system composition and technical characteristics

A complete wireless charging system for farming robots usually includes:

• Ground charging transmitter (TX side)
  Integrated power supply, coil and control module, installed at the robot docking point.
• Robot receiving end (RX side)
  Installed on the bottom or side of the car body, it is automatically aligned with the transmitter coil.
• Navigation and alignment system
  QR codes, UWB, visual guidance and other methods are used to ensure that the robot docks accurately.
• Communication module
  Realize charging status monitoring, power adjustment, abnormal protection and other functions.

Technical features include:

• More than 90% efficient wireless energy transmission
• Supports alignment tolerance ±20~50 mm, suitable for rough ground
• Support IP65 / IP67 protection level
• The charging current can be automatically adjusted according to the robot power

4. Application model examples

1. Cowshed inspection robot
   Complete tasks such as infrared temperature measurement, lying down identification, and feces detection, and automatically recharge between tasks.
2. automatic feeding cart
   Stop at the wireless charging area to replenish energy between daily feedings to improve feeding frequency and accuracy.
3. cleaning robot
   The floor cleaning and disinfection work is continuously carried out in the cattle and sheep sheds, and full-day operation is achieved through multiple short-term power supply.

5. Future development direction

1. Higher power density wireless charging, to meet the needs of large-scale feeding equipment.
2. Fully automatic docking intelligent dispatching system, enabling multiple robots to share multiple charging points.
3. Deep integration with digital ranching system, build a visual, data-driven breeding model.
4. Cross-category livestock application promotion, such as a unified energy supply system for intelligent equipment in pig houses and chicken houses.
