CubeMars Empowers the University of Minnesota’s Agricultural Quadruped Robot: Highly Integrated Motors Drive Smart Farming

A New “Farm Tool” in Smart Fields: The Quadruped Robot Dog Makes Its Debut

Across the vast farmlands of the University of Minnesota, a nimble quadruped robot dog weaves its way through the cornfields. Not only can it deftly avoid obstacles, but it also collects precise soil and crop data, performing tasks such as inspection and sampling. All of this is pushing the boundaries of what’s possible in smart agriculture.

Agricultural Quadruped Robots: An Intelligent Choice Beyond Tradition

Compared to traditional wheeled robots and drones, quadruped robot dogs offer unparalleled mobility and stability in complex terrains. Whether it’s muddy ridges, rolling hills, or dense crop rows, these robots navigate with ease, accomplishing tasks that conventional equipment simply can’t handle. Recognizing these advantages, the AG Lab team at the University of Minnesota is dedicated to developing intelligent quadruped robots tailored for a variety of agricultural scenarios.

The Motor Expert’s Choice: CubeMars AK70-10 Highly Integrated Modular Motor

When it came to selecting a power system for the robot dog, the team ultimately chose the CubeMars AK70-10 highly integrated modular motor. A star product among motor experts and quadruped robot enthusiasts alike, the AK70-10 offers several outstanding advantages:

• Highly Integrated Design: The motor, reducer, and driver board are combined into a single unit, greatly simplifying the robot dog’s joint structure and wiring, and enhancing system reliability.  

• High-Precision Control: Supports CAN bus communication for multi-motor synchronization and high-frequency position and torque control, meeting the demands of complex movements.  

• Powerful Torque Output: With a built-in 10:1 reduction ratio, it delivers high torque output, easily handling heavy loads and challenging terrain in the field.  

• Efficient Deployment: The integrated structure makes installation and maintenance more convenient, shortening the development cycle.

Control and Debugging: Rigorous Testing from Lab to Field

During the debugging process, the CubeMars AK70-10 demonstrated exceptional performance and stability. The team completed several key steps:

1. Establishing CAN communication with the STM32 control board to ensure efficient and reliable data transmission; 

2. Testing multi-motor synchronization for coordinated limb movement;  

3. Real-time monitoring and tuning via graphical interface position commands;  

4. High-frequency control after parameter optimization, ensuring smooth operation across complex terrains.

Currently, the AK70-10 motors are fully integrated into the robot dog’s core joints like hips, serving as the powerhouse of the entire motion system. As one team member noted, “The high integration and torque output of the AK70-10 have given our robot dog a tremendous boost in the field, greatly improving both our development efficiency and operational reliability.”

Looking Ahead: The Future of Quadruped Robots and Highly Integrated Motors

As smart agriculture continues to evolve, agricultural quadruped robots will take on more tasks such as data collection and precision operations, raising the bar for power systems. With its high integration and performance, the CubeMars AK70-10 is becoming the ideal choice in the field of intelligent robotics. Looking forward, this technology will also find broad applications in inspection, rescue, logistics, and more, helping the robotics industry reach new heights.

In closing, we sincerely congratulate the AG Lab team at the University of Minnesota on their groundbreaking progress in developing agricultural quadruped robots. We look forward to seeing this intelligent robot dog shine in future agricultural production, driving the vigorous growth of smart farming. We also wish the University of Minnesota team continued success and ever-greater achievements on their path of scientific innovation!
