Joydrive and Self Testshandle find its default centered position before starting to drive. Try exiting (reset) andrestarting joydrive mode if the joystick doesn’t seem to function well.The joystick’s “fire” button (button 1) acts as the joydrive “deadman”—press it to startdriving; release it to stop the robot’s motors. The robot should drive forward and reverse,and turn left or right in response and at speeds relative to the joystick’s position.When not connected with a client control program, releasing the joystick fire buttonstops the robots. However, when connected with a client, the client program resumesautomatic operation of your robot’s drive system. So, for example, your robot may speedup or slow down and turn, depending on the actions of your client program.You may adjust the maximum translational and rotational speeds, even disable joydrivemode, through special P2OS configuration parameters. See Chapter 7, Updating &Reconfiguring P2OS, for details.Engaging Self-TestsTo enable self-test mode, press the white MOTORS button twice after startup or RESET.15ATTENTION!Place your robot on the floor or ground and have everyone stepback before engaging self-tests.A message should appear in the LCD:Press again tobegin tests 13.2*And there should be that rhythmic beeping sound coming from the Console speaker toalert you that you may have engaged joydrive and self-test modes inadvertently. If so,press the red RESET button. If you really intended to run the self-tests, move on...Note that you may interrupt the current self-test and move on to the next one by pressingthe white MOTORS button. Or you may discontinue all testing at any time and return tothe P2OS servers’ wait state by cycling power or, better, by pressing the red RESET buttonon your robot’s Console.Motors TestThe first self-test exercises your ActivMedia robot’s drive motors. During this test, the robotis not at all conscious of bystanders. Please have everyone step back and remove anyobstacles from within a diameter of four to five feet around. When ready, press the whiteMOTORS button.The motors self-test begins by engaging the left drive wheel, first forward, then in reverse,each to complete a partial turn clockwise, then counterclockwise. Similarly, the rightwheel engages, first forward, then reverse to complete partial turns, firstcounterclockwise, then clockwise.The Console LCD, although difficult to read while the robot is in motion, displays amessage for each test. For example:Left forward13.2*15 As described above, the first MOTORS press and release puts the robot into joydrive mode.26
