轨迹编程代码用于控制机器人或无人机等移动设备沿着特定路径运动,常见的编程语言包括C++、Python和MATLAB等。以下是几种不同应用场景下的轨迹编程代码示例:
直线轨迹代码(Python示例):
```python
from dronekit import connect, Command, LocationGlobalRelative, VehicleMode
连接到飞行器
vehicle = connect('')
定义起始点和目标点的坐标
start_point = LocationGlobalRelative(39.9, -75.1, 10)
end_point = LocationGlobalRelative(40.0, -75.0, 10)
创建一条直线路径
cmds = [
Command(0, 0, 0, mavutil.mavlink.MAV_FRAME_GLOBAL_RELATIVE_ALT, mavutil.mavlink.MAV_CMD_NAV_WAYPOINT, 0, 0, 0, 0, 0, 0, start_point.lat, start_point.lon, start_point.alt),
Command(0, 0, 0, mavutil.mavlink.MAV_FRAME_GLOBAL_RELATIVE_ALT, mavutil.mavlink.MAV_CMD_NAV_WAYPOINT, 0, 0, 0, 0, 0, end_point.lat, end_point.lon, end_point.alt)
]
执行命令
for cmd in cmds:
vehicle.send_command(cmd)
```
使用偏移函数创建复杂路径(ABB RAPID编程语言示例):
```python
var robtarget p1;
var robtarget p2;
var robtarget p3;
// 定义基础点
p1 = new robtarget(100, 200, 0);
// 使用OFFS创建偏移点
p1_offset = new robtarget(p1.x, p1.y, p1.z);
p2_offset = new robtarget(p1.x + 60, p1.y, p1.z);
p3_offset = new robtarget(p1.x, p1.y, p1.z);
// 编写轨迹
movej(p1_offset, 1000, "fine", "tool0");
movej(p2_offset, 1000, "fine", "tool0");
movej(p3_offset, 1000, "fine", "tool0");
```
绘制3D动态轨迹(Python示例):
```python
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from matplotlib.animation import FuncAnimation
设置随机种子
np.random.seed(42)
生成随机的3D轨迹数据
def generate_trajectory(num_points=100):
t = np.linspace(0, 10, num_points)
x = t * np.sin(t)
y = t * np.cos(t)
z = t
return x, y, z
初始化图形
fig = plt.figure(figsize=(10, 8))
ax = fig.add_subplot(111, projection='3d')
生成轨迹数据
x, y, z = generate_trajectory()
设置图形标题和轴标签
ax.set_title("3D Dynamic Trajectory", fontsize=16)
ax.set_xlabel("X axis", fontsize=14)
ax.set_ylabel("Y axis", fontsize=14)
ax.set_zlabel("Z axis", fontsize=14)
绘制轨迹
line, = ax.plot(x, y, z)
更新函数
def update(frame):
line.set_data(x[:frame+1], y[:frame+1])
line.set_3d_properties(z[:frame+1])
return line,
动画
ani = FuncAnimation(fig, update, frames=range(1, len(x)), interval=50, blit=False)
plt.show()
```
