sorry,i made a mistake,the correct equation should be :
x*e^iθ - y*e^-iθ * e^-iα + z*e^iθ = d*e^iβ
d*e^iβ is the complex number of pin to tip vector,which β is known.
to DrClaude,
yes it may be have two answer,i just need the exact relation of θ and α.
hello friends,
when i build the mathmatical model of robot,i face a new question that i ever seen before.
i have a reverse kinematic lever as the leg and i want to use the tip position to get the relationship of fold angle and rotate angle reversely
here is my equation:
x*e^iθ - y*e^iθ *...
