Stepper motors are widely used in the field of robots, mainly due to their precise position control and simple drive mechanism. The following are its main applications and advantages:
Main applications
1. Joint drive
Robotic arm: used to accurately control the joint angle of the robot arm to ensure the accurate positioning of the end effector.
Humanoid robot: drive the joints of the legs, arms, etc. to achieve complex movements.
2. Mobile robot
- Wheeled robot: by controlling the speed and direction of the wheels, accurate linear and rotational motion can be achieved.
- Tracked robot: used to drive the tracks to adapt to complex terrain.
3. End effector
- Gripper: control the opening and closing of the gripper to achieve precise grasping.
- Tool operation: such as welding, spraying, etc., to ensure the precise positioning and operation of the tool.
4. Camera and sensor positioning
- Camera gimbal: control the camera angle to achieve all-round monitoring.
- Sensor scanning: used for rotational scanning of sensors such as lidar.
Advantages
1. Precise control
- Stepper motors are controlled by pulse signals, and the angle of each step is fixed, which is suitable for high-precision positioning.
2. Open-loop control
- Position control can be achieved without feedback devices, simplifying system design.
3. High torque
- High torque is provided at low speed, suitable for applications requiring great force.
4. Fast response
- Quick start, stop and reverse, suitable for frequent start and stop scenarios.
5. Simple structure
- Sturdy structure, easy maintenance, suitable for complex environments.
Challenges
1. Step loss problem
- Step loss may occur when the load is too large or the speed is too fast, and the drive circuit and mechanical structure need to be reasonably designed.
2. Heat generation
- Heat generation may occur during long-term operation, and heat dissipation needs to be considered.
3. Noise
- Noise may be generated during high-speed operation, which needs to be solved by optimizing the drive method or using silent technology.
Summary
Stepper motors are widely used in robots, especially in situations where precise position control is required. Despite challenges such as step loss, heat generation and noise, its high precision, high torque and fast response make it an ideal choice for robotic drives.
