Detailed Description

This tests checks the a position PID response, sending a step reference signal with a positionDirect command.

This test currently does not return any error report. It simply moves a joint, and saves data to a different file for each joint. The data acquired can be analyzed with a Matlab script to evaluate the position PID properties. Be aware that a step greater than 5 degrees at the maximum speed can be dangerous for both the robot and the human operator!

example: testRunner -v -t PositionControlAccuracy.dll -p "--robot icubSim --part head --joints ""(0 1 2)"" --zeros ""(0 0 0)"" --step 5 --cycles 10 --sampleTime 0.010" example: testRunner -v -t PositionControlAccuracy.dll -p "--robot icubSim --part head --joints ""(2)"" --zeros ""(0)"" --step 5 --cycles 10 --sampleTime 0.010"

Accepts the following parameters:

Parameter name Type Units Default Value Required Description Notes
robot string - - Yes The name of the robot. e.g. icub
part string - - Yes The name of the robot part. e.g. left_arm
joints vector of ints - - Yes List of joints to be tested
zeros double deg - Yes The home position for each joint
cycles int - - Yes Each joint will be tested multiple times
step double deg - Yes The amplitude of the step reference signal Recommended max: 5 deg!
sampleTime double s - Yes The sample time of the control thread
home_tolerance double deg 0.5 No The max acceptable position error during the homing phase.
filename string No The output filename. If not specified, the name will be generated using 'part' parameter and joint number
step_duration double s No The duration of the step. After this time, a new test cycle starts.
