A simple HTML slider that sends trajectory_msgs/JointTrajectory messages with Robot Web Tools' roslibjs: https://github.com/RobotWebTools/roslibjs
Written completely in HTML and JavaScript, so there is no need for a back end republisher.
Requires the roslib.js library, which can be found at: https://github.com/RobotWebTools/roslibjs/blob/develop/build/roslib.js
The range of the slider should be adjusted based on the range of the joint being controlled.
Usage:
- roslaunch rosbridge_server rosbridge_websocket.launch port:=<port_number>
- Open joint_trajectory_slider.html in your browser
