This Python library was written to facilitate closed-loop experimental protocol for biomechanics and motor-control related research.
Clone this repository, cd into the directory using either your virtual environment or your local environment, and run:
python setup.py install
from pywoodway.treadmill import SplitBelt, find_treadmills
import time
a_sn = 'FTHCUWVAA'
b_sn = 'FTHCUQ9IA'
a_port, b_port = find_treadmills(a_sn=a_sn, b_sn=b_sn)
if a_port is not None and b_port is not None:
print("Split belt treadmill found on ports", a_port, "and", b_port)
sb = SplitBelt(a_port.name, b_port.name)
sb.start_belts(True, False, True, False)
print("Belt A set to 2 MPH and belt B set to -2 MPH.")
sb.set_speed(2.0, -2.0)
print("Set incline to 20%")
sb.set_elevations(20.0)
time.sleep(10)
print("Split belt speed:", sb.get_speeds())
print("Split belt incline:", sb.get_elevations())
print("Belt A set to -2 MPH and belt B set to 2 MPH.")
# sb.set_speed(-2.0, 2.0)
time.sleep(10)
print("Split belt speed:", sb.get_speeds())
sb.stop_belts()
print("Split belt is stopped.")
sb.close()
else:
print("Split belt treadmill was not found.")
To find your Woodway treadmill with the script, plug in your treadmill to your computer and execute the following script,
from serial.tools import list_ports
ports = list_ports.comports()
for port in ports:
print(port.serial_number)
Write down the serial number for each treadmill (if using a split belt these are marked A and B) and pass those as arguments to the find_treadmills() function.
