Hello,
I have been trying to connect this gripper to the Sawyer however it doesn't seem to properly work.
Basically, if I run the example code
$ rosrun intera_examples gripper_cuff_control.py
everything works perfectly.
However, if I run this simple code:
# Sawyer Packages
import os
import rospy
import intera_interface
from intera_interface import Gripper
# Initialize ROS node, registering it with the Master
rospy.init_node('Sawyer_AssistiveGym')
# Create an instance of intera_interface's Limb class
limb = intera_interface.Limb('right')
# Enable the robot in case the emergency button was pressed
os.system('rosrun intera_interface enable_robot.py -e')
limb.move_to_neutral(timeout=15.0, speed=0.6)
# Use Gripper
arm = 'right_gripper'
_gripper = Gripper('right')
then I get the following error:
[INFO] [1635963926.594737]: Robot Enabled
[WARN] [1635963927.249393]: Specifying gripper by 'side' is deprecated, please use full name (ex: 'right_gripper').
Traceback (most recent call last):
File "/home/gabrigoo/assistive-gym/SawyrExp.py", line 17, in <module>
_gripper = Gripper('right')

raise OSError(errno.ETIMEDOUT, timeout_msg)
TimeoutError: [Errno 110] Failed to get gripper. No gripper attached on the robot.
Why is this happening?
Thanks in advance!
