+**robotiq_2f Repository** 
+
+***Overview***
+
+This repository provides a ROS2 integration for controlling the Robotiq 2F-85 and 2F-140 grippers. It combines elements from:
+
+* **ros2_robotiq_gripper:** [https://github.com/PickNikRobotics/ros2_robotiq_gripper/tree/main](https://github.com/PickNikRobotics/ros2_robotiq_gripper/tree/main)
+* **robotiq_2f_urcap_adapter:** [https://github.com/fzi-forschungszentrum-informatik/robotiq_2f_urcap_adapter/tree/main](https://github.com/fzi-forschungszentrum-informatik/robotiq_2f_urcap_adapter/tree/main)
+
+It leverages the low-level socket communication provided by the robotiq_2f_urcap_adapter to create a new ROS2-compatible hardware interface.
+
+***Features***
+
+* **robotiq_2f_controllers:**
+    * ForwardController
+    * GripperCommand
+    * RobotiqActivationController (inherited by ros2_robotiq_gripper) 
+* **robotiq_2f_description:**
+    * Configuration files for 85mm and 140mm grippers
+    * Controller configuration files
+    * Launch files for RViz visualization and controller activation
+    * Meshes for visualization and collision detection
+    * Modified URDF files
+* **robotiq_2f_interface:**
+    * ROS2 hardware interface 
+    * Robotiq2fSocketAdapter 
+    * MockRobotiq2fSocketAdapter
+* **robotiq_2f_msgs:**
+    * GripperCommand.action
+    * ForwardCommand.msg
+
+***Socket Communication***
+
+Socket communication details: [https://dof.robotiq.com/discussion/2420/control-robotiq-gripper-mounted-on-ur-robot-via-socket-communication-python](https://dof.robotiq.com/discussion/2420/control-robotiq-gripper-mounted-on-ur-robot-via-socket-communication-python)
+
+***Robotiq Resources***
+
+* **Robotiq UR Cap:** [https://robotiq.com/products/2f85-140-adaptive-robot-gripper?ref=nav_product_new_button](https://robotiq.com/products/2f85-140-adaptive-robot-gripper?ref=nav_product_new_button)
+* **Quick Start Guide:** [https://blog.robotiq.com/hubfs/Support%20Documents/QSG/Quick_start_2Finger_e-Series_nocropmarks_EN.pdf](https://blog.robotiq.com/hubfs/Support%20Documents/QSG/Quick_start_2Finger_e-Series_nocropmarks_EN.pdf)
+
+***Parameters***
+
+* `robot_ip`: IP address of the robot controller
+* `robot_port`: Port for robot controller communication
+* `use_fake_hardware`: Start gripper with fake hardware mirroring command to its states.
+* `use_forward_controller`: Use forward controller instead of gripper command controller(action controller).
+* `prefix`: In case multiple grippers are used on the same UR Cap.
+* `description_file`: The type of the Gripper (85/140) is decided here.
+
+**robotiq_2f_gripper (config file)**
+
+* `min_position`: 0.0 (fully closed)
+* `max_position`: 0.14 (fully open)
+* `max_angle`: 0.695 (radians, closed)
+* `min_speed`: 0.02 
+* `max_speed`: 0.15 
+* `min_force`: 20.0 
+* `max_force`: 235.0

-    # faster control cycles, and hence could improve stability in
