“…Implementing KFs on Lie groups is another widely studied line of designing filtering algorithms on manifolds, which was first proposed in [18,19]. Due to the systems' invariance properties, many studies proposed invariant KFs on Lie groups: the authors in [20][21][22][23] designed intrinsic continuous-discrete invariant EKFs (IEKFs) for continuous-time systems on Lie groups with discrete-time measurements in Euclidean spaces and applied them to attitude estimation and inertial navigation; in [24][25][26], the researchers proposed the invariant UKFs (IUKFs). To help practitioners fully understand IEKFs, Ref.…”

“…Since humanoid robot locomotion is hybrid and highly nonlinear by nature, possible future work aims at considering other nonlinear estimation techniques, such as the UKF or the particle filter, to further increase the estimation accuracy and also overcome the input-output correlation described in Chapter 3. Additionally, the Invariant EKF [142] and the Invariant UKF [143] have been employed in localization for mobile robots/UAVs and faster convergence properties have been demonstrated when contrasted to the EKF/UKF. Recently, such approaches proved effective also in humanoid base estimation [144,145], thus it is worth investigating whether geometrical properties such as left or right invariance also apply in CoM estimation.…”
