This is the Jacobian of a robot arm (IBB IRB 120) with already specified joint angles (0,0,0,0,0,0). This Jacobian is singular for this configuration.
J =
[ 0, 17/50, 7/100, 0, 0, 0]
[ 187/500, 0, 0, 0, 0, 0]
[ 0, -187/500, -187/500, 0, -9/125, 0]
[ 0, 0, 0, 1, 0, 1]
[ 0, 1, 1, 0, 1, 0]
[ 1, 0, 0, 0, 0, 0]
What motions are unachievable with this specific configuration? How to find that out conveniently with MATLAB?
