About
This tutorial shows you how to install and run AquaShoko in Gazebo via Ach and Ros
Install
Prerequisites
System Install
Download the AquaShoko-Gazebo project
$ git clone https://github.com/thedancomplex/AquaShoko-Gazebo
Switch to the feature/ach branch
# git checkout feature/ach
Build the project using CMake
$ cd AquaShoko-Gazebo $ mkdir build $ cd build $ cmake ../ $ make
Run
- Open Gazebo
- Add the AquaShoko-Gazebo folder to your path via the "insert" tab
- Insert the model ComplexAquaShokoLongLeg
Control Via ROS
In ROS AquaShoko uses the JointState message type to receive commands. The positions are set via modifying the "position" variable for each joint.
To activate the ROS functionality you must run the ROS controller:
# python roboControl.pyTopic
- Topic: aquashoko_chatter
- Type: JointState
Example ROS Controller
Below is an example ROS controller in Python that sets all joints to 5 degrees.
#!/usr/bin/env python import rospy from sensor_msgs.msg import JointState from std_msgs.msg import Header def talker(): val = 5 pub = rospy.Publisher('aquashoko_chatter', JointState, queue_size=10) rospy.init_node('aquashoko_talker') rate = rospy.Rate(10) # 10hz hello_str = JointState() hello_str.header = Header() hello_str.header.stamp = rospy.Time.now() hello_str.name = ['joint00', 'joint01', 'joint02', 'joint10', 'joint11', 'joint12', 'joint20', 'joint21', 'joint22', 'joint30', 'joint31','joint32'] hello_str.position = [val, val, val, val, val, val, val, val, val, val, val, val] hello_str.velocity = [] hello_str.effort = [] pub.publish(hello_str) i = 0 while not rospy.is_shutdown(): hello_str.header.stamp = rospy.Time.now() pub.publish(hello_str) rate.sleep() print i i = i+1 if __name__ == '__main__': try: talker() except rospy.ROSInterruptException: pass
