orocos-kdl中文注释之Geometric primitives(Twist+Wrench)

Twist是代表速度和角速度的6x1矩阵,Wrench是代表力和力矩的6x1矩阵,两者可相互转化

KDL::Twist

A Twist is the 6x1 matrix that represents the velocity of a Frame using a 3D translational velocity Vector?vel?and a 3D angular velocity Vector?rot:

Creating Twists
<equation>

Creating Wrenches
t = diff(F_w_A,F_w_B,timestep)//differentiationF_w_B = F_w_A.addDelta(t,timestep)//integration

t is the twist that moves frame A to frame B in?timestep?seconds. t is expressed in reference frame w using the origin of A as velocity reference point.
