什么是逆运动学，求解它有什么难点？
What is inverse kinematics and why is it hard to solve?
逆运动学是根据期望的末端位置姿态反求各关节角度的问题，与正运动学相反。由于多解、奇异点和非线性，常需迭代数值方法或优化算法才能稳定求解。
Inverse kinematics finds the joint angles needed to place the end effector at a desired position and orientation, the reverse of forward kinematics. Multiple solutions, singularities, and nonlinearity mean iterative numerical or optimization methods are often needed for stable solutions.

什么是强化学习在机器人中的应用？
What is the application of reinforcement learning in robotics?
强化学习让机器人通过试错获得奖励信号来逐步学会复杂动作策略，例如行走和抓取。它在仿真中训练后再迁移到真实机器人，可减少对人工编程的依赖。
Reinforcement learning lets a robot learn complex action policies through trial and error guided by reward signals, such as walking and grasping. Trained in simulation and transferred to real robots, it reduces reliance on hand-coded programs.

什么是SLAM技术？
What is SLAM technology?
SLAM（同步定位与地图构建）让机器人在未知环境中一边确定自身位置，一边绘制周围地图。它结合激光、摄像头和惯性传感器数据，是扫地机和自动驾驶的关键技术。
SLAM (Simultaneous Localization and Mapping) lets a robot determine its own position while building a map of an unknown environment. Fusing laser, camera, and inertial data, it is key to robot vacuums and autonomous driving.

什么是自由度，它对机械臂有何意义？
What is a degree of freedom and why does it matter for a robotic arm?
自由度是机器人可以独立运动的方向或旋转轴的数量。自由度越多，机械臂能到达的姿态越灵活，但控制和编程也越复杂。
A degree of freedom is an independent direction or rotation axis a robot can move along. More degrees of freedom let a robotic arm reach more flexible poses, but control and programming also become more complex.

什么是PID控制器，机器人为什么用它？
What is a PID controller and why do robots use it?
PID控制器根据误差的比例、积分和微分三项来调节输出，使系统快速且稳定地达到目标。机器人用它来控制速度、位置和姿态，是工业控制中最常见的算法。
A PID controller adjusts output from the proportional, integral, and derivative terms of an error, driving a system to its target quickly and steadily. Robots use it to control speed, position, and attitude, making it the most common industrial control algorithm.

什么是执行器？
What is an actuator?
执行器是把控制信号转化为实际运动的部件，例如马达、液压缸和气动元件。它相当于机器人的“肌肉”，负责真正去完成动作。
An actuator converts control signals into actual motion, such as motors, hydraulic cylinders, and pneumatic elements. It acts like a robot's muscles, responsible for actually performing actions.

机器人靠什么“看见”周围？
How do robots 'see' around them?
机器人通过摄像头、超声波、激光雷达等传感器来感知周围环境。这些传感器把光、声、距离等信息传给控制器，机器人据此判断障碍和路线。
Robots perceive their surroundings through sensors such as cameras, ultrasonic, and LiDAR devices. These sensors feed light, sound, and distance information to the controller, which then judges obstacles and paths.
