+IMU orientation test
+====================
+
+## Prerequisites
+
+If you want to test multiple IMUs at once, the robot must expose in its `yarprobotinterface` configuration file a `multipleanalogsensorsserver` that publishes the orientation measurements for all of available sensors, with a `prefix` that matches exactly the `port` parameter of the test (the default one is `${portprefix}/alljoints/inertials`). 
+
+An example of `alljoints-inertials_wrapper.xml` for iCubV2_* models:
+
+```sh
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE devices PUBLIC "-//YARP//DTD yarprobotinterface 3.0//EN" "http://www.yarp.it/DTD/yarprobotinterfaceV3.0.dtd">

+<device xmlns:xi="http://www.w3.org/2001/XInclude" name="alljoints-inertials_wrapper" type="multipleanalogsensorsserver">
+    <param name="period">      10                           </param>
+    <param name="name"> ${portprefix}/alljoints/inertials   </param>
+
+    <action phase="startup" level="10" type="attach">

+        </paramlist>
+       </action>
+
+    <action phase="shutdown" level="15" type="detach" />
+</device>
+```
+
+and `alljoints-inertials_remapper.xml`:
+
+```sh
+<?xml version="1.0" encoding="UTF-8" ?>
+<!DOCTYPE devices PUBLIC "-//YARP//DTD yarprobotinterface 3.0//EN" "http://www.yarp.it/DTD/yarprobotinterfaceV3.0.dtd">

+            (l_arm_ft r_arm_ft head_imu_0)
+        </param>
+        <action phase="startup" level="5" type="attach">
+            <paramlist name="networks">
+                <elem name="head_imu">  head_inertial_hardware_device </elem>
+                <elem name="left_arm_imu">  left_arm_inertial_hardware_device </elem>
+                <elem name="right_arm_imu">  right_arm_inertial_hardware_device </elem>
+            </paramlist>
+        </action>
+
+        <action phase="shutdown" level="20" type="detach" />
+    </device>
+
+```
+
+## Usage
+
+There are essentially two methods to install and run the IMU orientation test, which are going to be described in the following sections. In both cases, after launching the test, a .mat file containing the relevant measurements involved in the test will be generated.
+
+### robotology-superbuild
+
+If you have installed `icub-tests` as a part of the `robotology superbuild` framework with the [Robot Testing profile](https://github.com/robotology/robotology-superbuild/blob/master/doc/cmake-options.md#robot-testing) activation, i.e. by enabling the `ROBOTOLOGY_ENABLE_ROBOT_TESTING` CMake option of the superbuild, this test, like the others, is already available.
+
+In this case, after compiling and being sure that `yarpserver` is up, you can run:
+
+```sh
+cd robotology-superbuild/src/icub-tests
+robottestingframework-testrunner --suite suites/imu.xml
+```
+
+Otherwise, if you want to launch the test in a simulation environment, in a shell open a `gazebo` environment and import, for example, your iCub model. After that, open a separated shell, and:
+
+```sh
+#set YARP_ROBOT_NAME env variable with the name of the model you imported in gazebo
+#example:
+export YARP_ROBOT_NAME=iCubGazeboV2_7
+cd robotology-superbuild/src/icub-tests
+robottestingframework-testrunner --suite suites/imu-icubGazeboSim.xml
+```
+
+### pixi
+
+If you want to run the test without depending on the whole robotology-superbuild, you can use `pixi`. First of all, be sure to have [`pixi`](https://pixi.sh/#installation) installed. Then, clone `icub-tests` and run the test as a pixi task:
+
+```sh
+git clone https://github.com/robotology/icub-tests
+cd icub-tests
+pixi run imu_test
+```
+
+In simulation, instead, import your model in `gazebo` and then run:
+
+```sh
+#set YARP_ROBOT_NAME env variable with the name of the model you imported in gazebo
+#example:
+export YARP_ROBOT_NAME=iCubGazeboV2_7
+cd icub-tests
+pixi run imu_sim_test
+```
