ADInstruments PowerLab (for measuring EMG/EEG etc.)

The equipment has been borrowed from MedicoLab next door. It uses the PowerLab 16/35 which is an AD converter with 16 input channels (BNC connectors). It can be coupled with the Octal Bio Amp which uses another kind of connector (e.g. those used for EEG).

Recording process with LabView:

• Follow the instructions from the LabView tutorials.

Recording process with ROS bag:

• Connect the neccessary input channels into either the PowerLab 16/35 or Octal Bio Amp (ROS may only be configured for recording on channels 1-4).
  • If the Octal Bio Amp is used:
    • Connect the PowerLab and Octal Bio Amp with the i2c connector on the back (usually a grey cable)
    • Connect the BNC connectors on the backside to the PowerLab input connectors on the front.
• Connect the USB connection to a Windows PC with LabView and the custom-made Python script for streaming to ROS.
• Start LabView and then the Python script with the wanted settings. This makes it ready to be connected to a ROS-master.
• Start the white touch screen in the lab, that has been setup with Ubuntu and ROS.
• Start a ROS-master and run the package "powerlab_interface" with either launch file (e.g. emg_acc_cam.launch).
