2017-04-28 23:35:59 -0500 marked best answer rtabmap depth_registration ?

I am using rtabmap. rtabmap requires depth/image (sensor_msgs/Image). Does it need a rectified registered depth image or just the raw registered depth image?

I am guessing the registered depth image needs to be in meters.

2017-03-17 21:03:27 -0500 asked a question sensor_msgs/Imu Frame of reference?

What is the frame of reference for sensor_msgs/Imu?

It seems vague.

If the gyro rotate in counter clockwise direction around +Z direction is angular_velocity.z positive or negative?

If the robot is stationary then would linear_acceleration.z be +9.8 m/s^2 or -9.8 m/s^2 ?

If the robot moves from zero velocity to 1m/s in the X direction would linear_acceleration.x be positive or negative?

2017-01-24 22:51:23 -0500 asked a question ros-kinetic-robot on Arch Linux?

I installed ros-kinetic-ros-core 1.3.0-1 from the AUR in Arch Linux.

I also have poco 1.7.7-1 installed.

However, I can't seem to get ros-kinetic-robot 1.3.0-1 to compile.

Specifically this package ros-kinetic-diagnostic-aggregator 1.8.10-1.

When I do

yaourt -S aur/ros-kinetic-diagnostic-aggregator

this happens
