Michał Bednarek replied to the thread Make composite object less soft.

I have a very similar problem. I'm trying to grasp a soft object (composite/box) with a robotic gripper. Each experiment is performed...

Naveen Devinda liked Chinmay Swami's post in the thread [Resolved]How to acquire data from actual sensors and control the model?.

Hello Everyone, I have a model of an arm and want to control the arm in MuJoCo by using a myoware sensor mounted on my own arm. Is...

Naveen Devinda liked Chinmay Swami's post in the thread [Resolved]How to acquire data from actual sensors and control the model?.

I was able to figure it our and it was fairly simple. I just started with simulate.cpp and just added in my data acquisition code in it....

Emo Todorov replied to the thread How to get full submatrix of sparse jacobian?.

The equality constraints appear first in the list, but you cannot assume there are 3*neq rows in the Jacobian because different equality...

Make composite object less soft

I am trying to model a deformable object, think a paper box, like a package of cereals. I've attached an XML file to show how a heavy...

How to get full submatrix of sparse jacobian?

Hello, I'd like to use the equality portion of the constraint jacobian to write an optimization that minimizes equality constraint...

Emo Todorov replied to the thread Overlay/print data on mujoco sim window.

See the code sample simulate.cpp. It uses the internal tools for printing text on the screen. There is a simple function mjr_text(),...

Emo Todorov replied to the thread Orientation of robot hand in Quaternion.

It is great when problems solves themselves :) Yes the world coordinate system has the Z axis pointing up - which is why default...

Emo Todorov replied to the thread How to implement joint friction.

Sorry about the long delay. As you said, the soft constraint model in MuJoCo allows some slip even though the boundary of the friction...

Emo Todorov replied to the thread Qpos angular position outside of xml joint range.

Joint limits are soft, like all other constraints in MuJoCo. So the joint angle can be outside the range. If you change the softness...

Emo Todorov replied to the thread Is there a function that returns the starting index of a body in the q vector given its name?.

d->ctrl corresponds to actuators. Each actuator has a description in mjModel containing the transmission type and transmission id. The...

Iosif Petrov attached a file to the thread Is there a way to connect two clothes in several points?.

Hello, florianw, it works ideally for 5x5 count of clothes, but when we try to increase count of geoms to 18x30 it simulated wrong, as...

florianw replied to the thread Is there a way to connect two clothes in several points?.

Not that I have tried that, but I assume you could do that by specifying additional constraints in the xml. See...
