hector_quadrotor jumping on giving velocity commands #81

Open sidharthsharma96 opened 6 years ago

sidharthsharma96 commented 6 years ago

When I give velocity commands to the quadrotor it jumps. As in, if i only give a velocity command in z direction the quadrotor goes up with a acceleration and then comes back down. It's almost like firing a projectile.

All I am doing is : Launching the outdoor launch file. enabling the motors service and publishing velocity command to /cmd_vel Also, even if I publish an all 0 in the /cmd_vel the quadrotor still jumps in the +z-direction a little bit.

Is this part of the new update too?

Hi @hermesdragon I'm getting the same error with ROS Kinetic, you could fix it? I appreciate your help.

No. I never managed to make it work. There is a problem in the repo I believe. Ultimately, I had to go back to Ros indigo and use hector-quadrotor on that.
