Here's described how to construct the matrix T_RoLa whose definition is given in [ICubForwardKinematics](./icub-forward-kinematics.md). The matrix is constructed in two steps i.e. T_RoLa = T_Ro0 * T_0n. The first matrix T_Ro0 describes the rigid roto-translation from the root reference frame to points in the 0th reference frame as defined by the [Denavit-Hartenberg convention](./assets/chap3-forward-kinematics.pdf). In this case T_Ro0 is just a rigid rotation which aligns the z-axis with the first joint of the waist. The second matrix T_0n corresponds to the Denavit-Hartenberg description of the forward kinematic, i.e. the roto-translation from the 0th reference frame to the nth reference frame being n the number of degrees of freedom. The forward kinematic in this case includes the waist and the left arm forward kinematics.

Each of these matrices is constructed with two steps. The first consists in a rigid roto-translation from the points in the root reference frame to points in the 0th reference frame as defined by the Denavit-Hartenberg convention. The second step corresponds to the Denavit-Hartenberg description of the forward kinematic, i.e. the roto-translation from the 0th reference frame to the nth reference frame being n the number of degrees of freedom.
