RP6 ROBOT SYSTEM - APPENDIX
10. The robot is either not moving or moving slowly and/or starts blinking
four red LEDs immediately or shortly after a program's start!
●
The 4 LEDs will also start blinking on low battery voltage! Just connect the
robot to the PC and see if a low voltage warning appears if you click “Con-
nect” in the RobotLoader! If you press the robot's reset button and the Boot-
loader begins to wait for a start signal, low battery voltage will also cause
the four LEDs to start blinking! In this situation, the program may still be
started, but the robot will soon stop again and start flashing the LEDs...
●
If you are sure that batteries are fully charged and the status field of the Ro-
botLoader reports a battery voltage well over 6V, check for other error-mes-
sages in the terminal. One of the gearing systems or both may be blocked,
e.g. by over-tightened adjusting collars, by a gearwheel catching a cable, or
gearwheels interfering with other parts. Remove obstacles and carefully
loosen over-tightened adjusting collars should fix this.
●
Worst case, the motors or even the electronic control circuits may have been
damaged, which requires an exchange of damaged components... Please
start the selftest program #8 (Do NOT allow the robot to touch the floor
while the test is in progress – both caterpillars must be moving freely! Do
not block or brake the caterpillars manually! Blocking will immediately result
in a test failure!). The selftest program will check the motors and the elec-
tronic control circuits including the motor current sensors. Does the selftest
report any error messages? (We advise you to copy the complete terminal's
contents to a text-file e.g. by Menu “Options-->Save Terminal”).
●
Replacement of parts has been simplified for RP6v2. The two Motors and En-
coders now have connectors and can be disconnected from the Mainboard.
●
Replacement parts can be
ordered through Globalspecial-
ties. In case of a defect within
the warranty period you should
contact Globalspecialties via E-
Mail or Phone.
●
On the picture on this page you
can also see the new Poten-
tiometers (blue on this picture,
exact color and shape may
vary) that are used for fine ad-
justment of the new Encoders
on the RP6v2. These are now
way easier to access and to ad-
just.
