### 2023-10-28 更换局部规划器为dwa,同时使cmd_vel输出全向移动机器人的y方向速度而不是使用默认的yaw

### 2023-11-02 smooth the /cmd_vel, the output of the move_base, using ema formula.
### 2023-11-02 使用ema滤波算法平滑move_base的输出/cmd_vel.
由于move_base的输出/cmd_vel经常有速度的突变,且控制频率不高的条件下,会导致机器人运动卡顿,为了平滑机器人的运动,我们使用`velocity_smoother_ema`包(基于ema算法)对于输出的速度进行平滑处理,此处也可以使用`yocs_velocity_smoother`.
```bash
git clone https://github.com/seifEddy/velocity_smoother_ema.git

```
the launch file of velocity_smoother_ema has been added to sentry_movebase.launch file
velocity_smoother_ema的启动已经添加至sentry_movebase.launch file,并且现在串口订阅的是滤波后的速度即`/smooth_cmd_cel`
### 2023-11-02 make a little bit change to sentrial_serial.
- using rosparam for imparting the parameters
- now suscribe to the `/smooth_cmd_cel` topic
- add a launch file
- 使用rosparam传递参数
- 现在串口订阅 `/smooth_cmd_cel` 话题
- 增加了一个launch file并设定了参数
