title: (ROS node) for Euler Integration to estimate Velocity knowing the acceleration
body: <p>I have an IMU reading and would like to estimate the linear velocity using the Euler method based on the linear acceleration from the IMU.aware of the accumulated errors. So I need a C++ (python) code (possibly a ROS node) that takes the IMU data reading from the IMU sensor and gives the estimated linear velocity using Euler Integration.</p>
  <p>I know that acceleration a is <code>a=dv/dt</code></p>
  <p>and that will be the function.Then <code>dv/dt = f(t) . i.e. v(n+1) = v(n) + f(n) * dt</code></p>
  <p>So how are the steps calculated? I have the timestamps from the ros topic. So any help with the C++ (ROS node) code?</p>
