Robot error model

Robot error model

 The forward and inverse error model can be expressed as the following two equations:
[ΔP,ΔR]T=J[Δθi]       i=1,2,...N    (3)

[Δθi]=J-1 [ΔP,ΔR]T       i=1,2,...,N    (4)

Where J is Jacobian matrix and J-1 is inverse Jacobian matrix.

For N measurements, we define the fitness function (FF), as:
