MyController S570 Control X1 program case

Connect the exoskeleton to Mercury via USB and save the following script file. Note: Make sure each serial number corresponds to the correct device

1.Use example

Operation tutorial:

Turn on the side switch before inserting Type-C

Turn on wifi:

Press button A, IP is displayed for use, wifi account number: elephant, wifi password elephant

Turn off wifi: press button C

Turn on Bluetooth:

Press button B, display BT can be used, Bluetooth name BLE

Turn off Bluetooth: press button C

1.1 Serial communication

# example
from pymycobot import Exoskeleton

# Connect the serial port
obj = Exoskeleton(port="COM5")

# Get dual-arm data
all_data = obj.get_all_data()
print(all_data)

# Get left arm data
left_data = obj.get_arm_data(1)
print(left_data)

# Get right arm data
right_data = obj.get_arm_data(2)
print(right_data)

# Obtain single arm and single joint data
joint_data = obj.get_joint_data(1, 1)
print(joint_data)

# Set the current position to zero on right arm J7
obj.set_zero(2, 7)

# Set the left arm atom screen color
obj.set_color(1, 0, 255, 0)

1.2 socket communication

# example
from pymycobot import ExoskeletonSocket

# Connection server
obj = ExoskeletonSocket()

# Get dual-arm data
all_data = obj.get_all_data()
print(all_data)

# Get left arm data
left_data = obj.get_arm_data(1)
print(left_data)

# Get right arm data
right_data = obj.get_arm_data(2)
print(right_data)

# Obtain single arm and single joint data
joint_data = obj.get_joint_data(1, 1)
print(joint_data)

# Set the current position to zero on right arm J7
obj.set_zero(2, 7)

# Set the left arm atom screen color
obj.set_color(1, 0, 255, 0)

Note: Keep the two files in the same path

After successful operation of the program, Mercury X1 can be controlled with the exoskeleton

Case 1: Exoskeleton controls Mercury X1+ three-finger dexterous hand to drill holes with electric drill
