云迹机器人底盘调用还是比较友好的，就是纯socket收发指令就能实现，今天实现一个底盘移动到指定点位功能。底盘的默认IP是192.168.10.10通讯端口是31001，测试机与底盘接入统一网络后直接发指令即可。本文给出两种语言调用源码，选择一种使用即可。

python调用源码：

import socket
import jsonyunji_ip = "192.168.10.10"#设定地盘ip地址，需要根据机器人实际ip地址修改#底盘-移动到指定为止
def YunjiGo(target):print(f"---------------------YunjiGo:{target}---------------------")port = 31001command = "/api/move?marker=" + target + "&distance_tolerance=0&theta_tolerance=0"client = socket.socket()client.connect((yunji_ip, port))print(f"command:{command}")client.send(command.encode())while True:try:data = client.recv(1024)if not data:print("Socket closed by peer.")return Nonestr_data = data.decode('utf-8')split_data = [s for s in str_data.split('\n') if s]for s in split_data:try:json_data = json.loads(s)print(json_data.get("description"))# 检查条件：任务完成且目标匹配if (json_data.get("description") == "The move task is finished."and "data" in json_dataand "target" in json_data["data"]and json_data["data"]["target"] == target):print("Task finished successfully!")client.close()  # 关闭 socketreturn True     # 返回成功except json.JSONDecodeError:print("Invalid JSON data, continue waiting...")continueexcept socket.timeout:print("Timeout reached, no matching data received.")return Noneexcept Exception as e:print(f"Error occurred: {e}")client.close()  # 确保异常时关闭 socketreturn None
YunjiGo("huahua")#移动到点位huahua

JAVA调用源码：（需要下载org.json-20161124.jar）

}

运行输出：

------------YunjiGo------------The move task is started.
Start to leave charging pile..
Charge status off.
Succeed to leave charging pile.
traffic turn right.
traffic turn right.
The move task is finished.
Task finished successfully!
