4 举个栗子
以turtlebot3为例,程序调用好之后
重新打开一个终端,参考上面的“3.2”输入
rosservice call /gazebo/apply_body_wrench "body_name: 'turtlebot3_burger::base_footprint'
reference_frame: 'turtlebot3_burger::base_footprint'
reference_point: {
x: 0.0, y: 0.0, z: 0.0}
wrench:
force: {
x: 0.0, y: 1.0, z: 0.0}
torque: {
x: 0.0, y: 0.0, z: 0.0}
start_time: {
secs: 0, nsecs: 0}
duration: {
secs: 5, nsecs: 0}"
rosservice call /gazebo/apply_body_wrench "body_name: 'turtlebot3_burger::base_footprint'
reference_frame: 'world'
reference_point: {
x: 0.0, y: 0.0, z: 0.0}
wrench:
force: {
x: 0.0, y: 0.0, z: 10.0}
torque: {
x: 0.0, y: 0.0, z: 0.0}
start_time: {
secs: 0, nsecs: 0}
duration: {
secs: 10, nsecs: 0}"
似乎duration里面的nsecs值设为-1的话,就是持续施加力了。
