#Actions server download code#
We can configure the effort controller transmission of a joint named joint1 rapidly by the block of code below. Gazebo controllers need the corresponding transmission interface in URDF file. Transmission-specific code (not robot-specific) implementing bidirectional effort and flow maps under a uniform interface shared across transmission types. A transmission is an element in a control pipeline that transforms efforts/flow variables. There is a big difference between RViz visualisation and Gazebo simulation, the former one is used to display relative position of links, but the later one can be regarded as a experimental copy of real robot in virtual world. Controlled experimental setups can easily be created in which subjects can interact with manipulators in a realistic manner. Numerous researchers have also used Gazebo to develop and run experiments solely in a simulated environment. By realistically simulating robots and environments code designed to operate a physical robot can be executed on an artificial version.

It generates both realistic sensor feedback and physically plausible interactions between objects (it includes an accurate simulation of rigid- body physics). Like Stage (part of the Player project), it is capable of simulating a population of robots, sensors and objects, but does so in a three-dimensional world.

Here are some brief introduction about main active nodes and topics transported between each other(i.e.

Launching RViz node and other essential nodes to establish a ROS network which can control the position of each joint provides a simple method to check the joint connection between links. RViz has a Graphical User Interface (GUI) to allow users to configure and modify robots. visualization tool of ROS which can be used to display the topics communicated between nodes.
