help with Operator Interface and FRC robot Controller
Hello
I have make a submarine and I will use Operator Interface and FRC robot Controller to control my 4 motors (thrusters) on submarine. Sow I need some help with my Operator Interface and FRC robot Controller. The Operator Interface and FRC robot Controller is new,sow i dont no what I shall do.however I have connect all cables,2 Analog joystick and the 4 Motor Controls to FRC robot Controller and the Operator Interface,I use two RS232 converter to RS485 instead of Radio Modem, because the Radio Modem don`t work under the water, sow I have a long cabel. When I power up Operator Interface and the FRC robot Controller with RS232 converter to RS485, the LEDs indicator on Operator Interface and FRC robot Controller indicate this: FRC robot Controller Battery Power : GREEN Blink Program State : GREEN Blink Radio Modem : RED Solid RC Hardware : GREEN blink RC Mode : OFF/ no LED Operator Interface Operator Interface POWER ON : GREED Solid DATA TX : GREED Solid VALID RX : GREED Solid NO DATA/Radio : NO LED MAIN Fault : NO LED AUX Fault : NO LED RADIO Fault : NO LED INTERNAL Fault : NO LED Robot controller VALID RX : GREEN Blink NO MAIN BATT : RED Solid LOW MAIN BATT : Orange Solid CODE ERROR : RED Solid BACKUP BATT : NO LED I will take a photo off Operator Interface and the FRC robot Controller to morrow. |
Re: help with Operator Interface and FRC robot Controller
read the manual, at innovation first...
you have no radio connection, use a red "teather"(a serial cable with 2 male ends), then/or plug in the radios... |
Re: help with Operator Interface and FRC robot Controller
I think u got 3 problems. 1 its not reconizing a main battery, or its seeing it as very low. 2 it doesent like your code. 3 it doesent like what your doing with the radios. That's all I got.

Re: help with Operator Interface and FRC robot Controller
If the tether isn't plugged into the "Tether" port on either the Robot Controller or the Operator Interface, it won't work. You'll need a red tether as noted (or an equivalent M-M or F-F (I forget just which)) due to the fact that the ports are the same on both the Operator Interface and the Robot Controller.

You need RS-422 not 458, but you can use the tether cable. Also if you modify the Antenna on the radios, they will work under water. |
Re: help with Operator Interface and FRC robot Controller
Use the tether ports. But you want a longer cable. We cut the tether cable in two and inserted used some old multi line phone cord. We used some of the extra wires for camera and other sensors. More info at:
http://www.phxhs.k12.az.us/education...detailid=44216 Watch the waterproofing. The water pressure will force water through the tiniest opening, even a nick in a cable. |
Re: help with Operator Interface and FRC robot Controller
ok, I have remove the RS485 converters from Tether,and hook up a Female-Female cable, all LEDs on Operator Interface and Robot controller is GREEN.
You can see this on image. ![]() ![]() Sow I can not use a RS485 converters into the Tether port. I need a longer cable about 100 Meter,how can I do that. I have talk to http://www.ifirobotics.com they say I can use a RS485 converters, with RS 485 can you use 1000Meter cabel with only 2 Wire TX- TX+ What shall I do no,to run the 4 speed controllers and the 4 motor, forward,reverse? you can see on the image I have hook up 2 Analog joystick to control the 4 motor. I have never do this before. |
Re: help with Operator Interface and FRC robot Controller
With the setup you have, the default code should work. (I'm not sure exactly how to set it up, but I think you've got it set right.) Try moving one stick forwards and backwards or side-to-side. Make sure that the robot won't move first! Hopefully, one of the motors will turn on. If nothing happens, the programmers should be able to help.
But, make sure the "Disable" light on the Operator Interface is off first. (I can't tell from the picture--the light reflects at the wrong color. It looks like it's off.) |
Re: help with Operator Interface and FRC robot Controller
You will also need to connect your motors to Victor 884 Speed Controllers (or similar) which are connected by PWM cable (3 wire, 0.100" spaced pins) to the RC. I forget the outputs to which the default code outputs, I'm sure someone else here will chime in.

Re: help with Operator Interface and FRC robot Controller
Well then if you want to use the RS485 Convertors, you have to connec them to the RADIO porst instead of tether. the tether port is not a standard serial cable, it provides power to the OI as well as the data.

Re: help with Operator Interface and FRC robot Controller
ok.
I have moving one stick forwards and backwards,but nothing happens. I have connect they 4 Speed Controllers to PWM1 PWM2 PWM3 PWM4 I have not use Victor,I have use Speed Controllers from parallax.com I will try to connect the RS485 Convertors to the RADIO porst,and se whats happen. What do you mean about that But, make sure the "Disable" light on the Operator Interface is off first |

Your joysticks should be wired per the analog inputs in the OI manual. For each axis - one side of 100k linear pot to an analog input pin , center to +5vdc aux pin, other side not connected. It looks like your joysticks are not centered. The OI LEDs for pwm1 and pwm2 should be on green and red to indicate neutral. Last, check the compatibility of the paralax speed controllers to the output from the RC pwm signals. Good luck, p |

If it is on, I'm not sure how to take it out of disabled mode without a dongle (fancy switch). The schematic for one is available on IFI's site. It might be a good idea to make one anyway, just to help the robot run only when you want it to. |
Re: help with Operator Interface and FRC robot Controller
now I have try to connect the RS485 converters to the RADIO porst,but dont work, after I have remove RS485 converters from RADIO porst,and hook up the Female-Female cable into the Tether port again,come only 1 GREEN LED and 1 Yellow LED on FRC robot Controller.same on the Operator Interface ,but is have 2 Green Led and 1 Red Led
FRC robot Controller Battery Power : GREEN Program State : YELLOW Radio Modem : no LED RC Hardware : no LED RC Mode : OFF/ no LED Operator Interface POWER ON : GREED DATA TX : GREED NO DATA/Radio : RED LED sow what happen? Is the FRC robot Controller or Operator Interface broken |
