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 json

yunji_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 = 31001
    command = "/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 None

            str_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_data
                        and "target" in json_data["data"]
                        and json_data["data"]["target"] == target
                    ):
                        print("Task finished successfully!")
                        client.close()  # 关闭 socket
                        return True     # 返回成功

                except json.JSONDecodeError:
                    print("Invalid JSON data, continue waiting...")
                    continue

        except socket.timeout:
            print("Timeout reached, no matching data received.")
            return None
        except Exception as e:
            print(f"Error occurred: {e}")
            client.close()  # 确保异常时关闭 socket
            return None
YunjiGo("huahua")#移动到点位huahua

运行输出：

------------YunjiGo------------

Start to leave charging pile..
Charge status off.
Succeed to leave charging pile.
traffic turn right.
traffic turn right.
The move task is finished.
