First fare 2010 field connectivity First fare 2010 field connectivity Presentation Transcript

  • Field Radio
  • Game Adapter WRT600 WET610N
  • cRIO
  • Driver Station
  • Camera
  • Driver Station ‘Router’ WRT610N WRT160N
  • Basic Networking TCP/IP connected devices  Wireless  Wired Parts of an IP config  IP address (  Subnet mask (  Default gateway (  In this example, 10 is network and 15.40.1 is host  If you change the mask to, then 10.15.40 is network and 1 is host  For FIRST, you are basically talking within your own subnet
  • More Basic Networking Wireless/Radio terminology  Band 5Ghz  Channel 36  SSID 1540  Vlan 1540  Association Basic Tools  Ping is your friend  There are others (ipconfig, tracert, arp, netstat)
  • Field RadioSSID 1540
  • Game Adapter10.15.40.1 WRT600
  • cRIO10.15.40.2
  • Driver Station10.15.40.5

  • FIELD Connectivity FMS tells the router and field radio to set up the field for team 1540  Field Radio broadcasts SSID 1540  Vlan 1540 is ready to talk to devices with 10.15.40.x addresses  Ditto for the other 5 teams on the field Traffic from the DS goes to the field networking equipment via ethernet connection, out field radio to GA on robot, through ethernet to cRio Traffic from the cRio goes through ethernet to GA, over wireless SSID to field radio, back to field network gear and DS through ethernet Ditto for the other 5 teams on the field….
  • Avoiding “No Comms” Devise pre and post match checks for your robots and then DO them consistently ;-) Don’t monkey with the network settings on your devices – set them up as instructed in the FIRST documentation OR at the advice of FTA Keep your DS Operating System clean. Malware can impact your ability to effectively talk on a network
  • Avoiding “No Comms” Make sure you have good, solid power to GA and cRio (as in, no loose cables) Make sure you have nice, solid ethernet to cRio and DS  No loose cables (robot gets banged around…)  No bad spring pins  No junk in the interface ports  Be friendly to the classmate ethernet jack
  • Avoiding “No Comms” Location, location, location ;-) Mount the GA someplace happy.  Pay attention to that cute little reset button  Bumps!  “damped, non oscillary mount”  You need quick access to GA and cRio on the field
  • Avoiding “No Comms” Location, location, location ;-) Wireless communication is inherently moody – there are boatloads of things that affect it, and we can’t SEE any of them with our eyes...  No conductive surfaces  Static!  Orientation of internal antenna…  Don’t bury the GA deep in the robot  Don’t encase in metal or other things that interfere with radio waves  Avoid polycarb ;-)  Avoid high EM fields (translate: Motors, power lines)  Avoid faraday cages (steel frames ;-))
  • Avoiding “No Comms” Boot sequence on the field  Come to the field with your DS and Robot off  Wait for your team # on the display  Boot up DS, login as driver and wait for happy green lights on DS  Power up robot  Smile, and have a good match The FTA is your friend ;-)
