WJZ_Chassis

概述:ROS机器人底盘驱动,PC端包,主要针对差分驱动机器人和阿克曼转向的无人驾驶汽车,如果发现BUG或者需要我更新新的算法,或者需要技术合作,可以联系我修改或者pull request,如果觉得这个项目好请给我颗星星或者branch,这个项目会不断更新,谢谢大家!
Overview: ROS chassis pkg for Differential drive robot and Ackermann steering robot like autocar,If you find a bug,or need me to update the new algorithm,or need technical cooperation, you can contact me to modify or pull the request. If you think this project is good, please give me a star or branch. This project will be constantly updated, thank you!

算法大概介绍见(algorithm introduction):/doc

Dependece

1.ros (based on ros)

contents:

1.Diff Robot

具体可见/doc介绍,代码如下:
now_pose.x += v*dt*cos(now_pose.th);
now_pose.y += v*dt*sin(now_pose.th);
now_pose.th += w*dt;
需要机器人用USB或者通过在机器人上放一个MCU如stm32,通过stm32读取驱动器/编码器的信息传输给PC段/MPU端,而PC端收到后发送odom消息和相应tf,同时如果PC端收到上层算法的消息,则发送给机器人的MCU端,该程序是PC端程序,因为stm32那个很简单就不写了。

2.Ackermann Steering

具体可见/doc介绍,代码如下:
now_pose.x += v*dt*cos(now_pose.th);
now_pose.y += v*dt*sin(now_pose.th);
now_pose.th += v/wheel_base*tan(steer)*dt;
需要无人车支持CAN并通过USBCAN连接到PC端,然后通过其他程序转述,这个只是例子,为了展现其运动学模型。
