The problem is that the quaternions given in id: 4 distance: 1048 q0: 646 q1: -232 q2: -119 q3: 717 are not normalized. In fact, $$\|\textbf{q}\| = \sqrt{q_0^2+q_1^2+q_2^2+q_3^2} = 999.6950$$ I suspect the wearable device gives the quaternions using fixed point numbers that must be scaled by dividing by 1000. Another problem is that the quaternions are ...

It's telling you it can't reach the solution in the number of steps you've given it. As Akshay Kumar stated, you need to be sure that the robot arm can actually reach the desired target. I've used LabVIEW, but it's been a long time - I don't know what your parameters are doing or what you have set on the front panel, but it looks like you're passing a lot of ...

There could be a few generic reasons. Ensure that the desired Cartesian pose is actually achievable by the robot, i.e the position is within the workspace. As the error mentions about max_steps parameter, I believe they are using random restarts for something like a Jacobian pseudoinverse based solver; so indeed try giving more steps because intricate ...

Unfortunately, there is no "single" answer to your question. There is no USB port on the NI myRIO, so just using the cable provided by iRobot as-is is not really an option. The good news is the iRobot Create (and Roombas in general) take all of their commands via the serial 7DIN interface that is mounted on-top of Roomba. The Create 2 should have some re-...
