Forward Kinematics Methods
« on: March 07, 2008, 02:43:46 PM »
What are the alternative methods for forward kinematic conventions apart from D-H conventions?

I have searched various links but most of them proposes D-H one

Can you help me?

D-H is what you want if you are solving it by hand (lots of crazy linear algebra). If you are using a computer you want to use the Jacobian Matrix method (still a ton of math but a symbolic solver like mathematica can do a lot of it for you).

actually it is a homework and i couldn't find any alternative method for D-H except only quaternions, is it sufficient ?

jacobean is as far as i know is the velocity kinematic method, isn'i it ?

Yea, Jacobeans is for mapping joint velocities . . .

How many joints does the arm have? Another method is just highschool geometry and trig ;D
