The Lie Algebra for Lie Groups in Robotics

Abig part of why we use Lie groups for robotics is because they enable efficient optimization for large scale robotics problems. The reason why Lie groups enable this is because we can represent objects like rotation matrices in lower dimensions and perform unconstrained optimization inste...

From 2020 to the present I do not know what it is like to be a shepherd, but I do know when I am trying to care and when I am being cared for. The people on horses walk with the cattle to guide them and rescue them when one goes astray. The fences that animals rub against, push through, jump over...
