  • Added get_angle() which gets the direction of the robot relative to the position of the last reset_odometer().
  • Added full ramp up and down for all robot motions
  • Rewrote mote code to reduce program memory used on the motes ahead of the next feature

5 Apr 2014

  • Socket Comms
    • Added Motion Complete to Socket Broadcast
      Sends DMC to all clients
    • Broadcast Sets
      • Add a Broadcast Set for Vision
        Send 3VS to start vision packets as data is sent. Send char* packets with [0] == length of msg to vision_sock[1]
        Send 3VF to stop vision packets
      • Add a Broadcast Set for Motes
        Send 3MS to start mote packets as data is received from the device.
        Send 3MF to stop mote packets
      • Add Mote Control
        Send 2WS to start the mote connection
        Send 2WF to stop the mote connection
      • Start Vision Processing
        Send <4+>VS<name> to start the <name> vision library processing
        Current library name options: zbar, barcode

4 Apr 2014

  • Vision
    • New CV Processing System is Operational
      Starts CV processing and camera capture on flockbot start, then blocks for vision library selection.
      Supports swapping between vision libraries during program runtime.
      Use shutdown_run() to stop the library before switching or ending your program.
    • Libraries
      • zbar is Fully Functional
        zbarcode_run() starts the processing using future socket command "zbar"
        int**zbarcode_get_barcodes() returns a 2d array. Row is identified barcode id. Col: 0-barcode, 1-x avg, 2-height
        zbarcode_get_cur_x(id) Gets the avg x of the barcode with specified id, only if it is still current
        zbarcode_get_cur_y(id)
        zbarcode_get_last_x(id) Gets the avg x of the barcode with specified id
        zbarcode_get_last_y(id)
        zbarcode_start(RaspiCamCvCapture*) Internal to start the library from the vision processing system.
      • barcode is Functionally Operational (pending API)
        barcode_run() starts the processing using future socket command "barcode"
        barcode_get_barcodes() returns the id of the first barcode on the last scan
        barcode_start(RaspiCamCvCapture *) internal to start the library from the vision processing system.
