kandi X-RAY | double_pendulum Summary

double_pendulum is a JavaScript library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Tensorflow, Numpy applications. double_pendulum has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

In physics and mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions. The motion of a double pendulum is governed by a set of coupled ordinary differential equations and is chaotic. Several variants of the double pendulum may be considered; the two limbs may be of equal or unequal lengths and masses, they may be simple pendulums or compound pendulums.

QUESTION

Is np.linalg.solve() not working for AutoDiff?

Asked 2020-Oct-29 at 21:01

Does np.linalg.solve() not work for AutoDiff? I use is to solve manipulator equation. The error message is shown below. I try a similar "double" version code, it is no issue. Please tell me how to fix it, thanks!

Note that in pydrake, AutoDiffXd scalars are exposed to NumPy using dtype=object.

There are some drawbacks to this approach, like what you have ran into now.
This is not necessarily an issue with Drake, but a limitation on NumPy itself given the ufunc's that are implemented on the (super old) version that is on 18.04.

To illustrate, here is what I see on Ubuntu 18.04, CPython 3.6.9, NumPy 1.13.3:

Is Drake correctly obeying joint limits?

Drake doesn't strictly obey the joint limits during simulation. It treats the joint limits as if a spring-damper system. When the joint exceeds the joint limits, the spring damper system applies a larger restoration force to push the joint back to within the joint limits.

Is there a way to check this using the API and cout to the screen. Is there a way to read joint state from the simulation?

You could use SignalLogger system, one example is in https://github.com/RobotLocomotion/drake/blob/9c30d5b73580616badd75905da7733ff64663bb8/examples/manipulation_station/joint_teleop.py#L118-L120, you could construct a SignalLogger, connect it to the robot state port, and after the simulation, you could read the logged robot state, similar to https://github.com/RobotLocomotion/drake/blob/9c30d5b73580616badd75905da7733ff64663bb8/examples/manipulation_station/joint_teleop.py#L157-L163
