The simple_robot_control library provides a simple interface to move the PR2s arms, grippers, base, head and torso. C++ and Python API available. Arm, Gripper, Head, Base and Torso objects can be instantiated and calling their functions will move the robot. For moving the arms in cartesian space the arm planners need to be launched by calling:

launch/simple_robot_control_without_collision_checking.launch

or to enable planning with obstacle avoidance

launch/simple_robot_control.launch

C++ interface:

#include <ros/ros.h>

#include <simple_robot_control/robot_control.h>


int main(int argc, char** argv){



        ros::init(argc, argv, "robot_control_test_app");
        ros::NodeHandle nh;

        //Create robot controller interface
        simple_robot_control::Robot robot;

        //look straight
        robot.head.lookat("torso_lift_link", tf::Vector3(0.1, 0.0, 0.0));

        //do stuff with arms
        robot.left_arm.tuck();
        robot.right_arm.stretch();

        //specify joint angles for two waypoints
        double tuck_pos_right[] 
           = { -0.4,0.0,0.0,-2.25,0.0,0.0,0.0,
               -0.01, 1.35, -1.92, -1.68, 1.35, -0.18,0.31};
        std::vector<double> tuck_pos_vec(tuck_pos_right, tuck_pos_right+14);
        robot.right_arm.goToJointPos(tuck_pos_vec);

        robot.right_arm.stretch();

        //grab position from above
        robot.right_arm.moveGripperToPosition(tf::Vector3(0.6,-0.1, 0.0),    
                 "torso_lift_link", simple_robot_control::Arm::FROM_ABOVE);
        
        //grab position frontal
        robot.right_arm.moveGripperToPosition(tf::Vector3(0.8,-0.1, 0.1), 
                    "torso_lift_link", simple_robot_control::Arm::FRONTAL);

        //specify grab pose with postion and orientation as StampedTransform
        tf::StampedTransform tf_l (tf::Transform(tf::Quaternion(0,0,0,1), 
           tf::Vector3(0.8,0.1,0.0)),
           ros::Time::now(),"torso_lift_link","doesnt_matter");
        robot.left_arm.moveGrippertoPose(tf_l);

        //look at left gripper
        robot.head.lookat("l_gripper_tool_frame");

        //drive 0.5m forward
        robot.base.driveForward(0.5);

        //raise torso to 10cm above lowest position
        robot.torso.move(0.1);

        return 0;
