安装说明在README.txt中。依据Ubuntu系统版本安装x64或x86版本程序包。
$ sudo dpkg -i Leap-2.3.1+31549-x64.deb
不报错即可安装完成,如果出错,例如如下:
$ sudo dpkg -i Leap-2.3.1+31549-x64.deb

这时,需要忽略liggl1-mesa-glx,这和系统已经安装的包冲突了。

2. Leap安装故障排除
配置:
$ sudo apt-get install ros-indigo-leap-motion
$ sudo cp Robotdemo_ws/LeapSDK/lib/x64/libLeap.so /usr/local/lib/
.bashrc
export LEAP_SDK=$LEAP_SDK:/home/relaybot/Robotdemo_ws/LeapSDK
export PYTHONPATH=$PYTHONPATH:/home/relaybot/Robotdemo_ws/LeapSDK/lib:/home/relaybot/Robotdemo_ws/LeapSDK/lib/x64
安装:
https://github.com/juancamilog/leap_client
启动:
$ roslaunch leap_client leap_client.launch
$ rviz
Leap Motion在github上还有一些功能包可供参考,可以进一步理解和掌握ROS和Leap Motion的使用。
---------------------
2. 机械手配置
这里,给出一些机械手的示例供参考,选择一款进行实验,仿真和实物皆可,通常而言仿真更为方便。
机械手可以在如下链接进行查找:http://robots.ros.org/
其中很多都有Gazebo模型可以用于仿真学习,当然也可以选择带有机械手的机器人。
http://wiki.ros.org/shadow_robot/Tutorials
---------------------
3. 综合实验
方案提示:
1. 将Leap各个手指关节位姿与机械手位姿进行映射,使得机械手跟随Leap位姿变化进行随动。(任意位姿)
2. 设定一些特征手势,Leap识别当前手势并发送消息给机械手,机械手响应做出对应手势。(特定位姿)
3. 其他有创意的方案也可以。
具体实现过程稍后再做补充。
