  • Publication number: 20220195689
    Abstract: One example is directed to an end effector position estimation system for an off-road vehicle, which includes at least one inertial measurement unit (IMU) configured to be positioned on at least one of actuators and links of the vehicle that together move the end effector of the vehicle, and configured to generate measurement signals. The position estimation system includes at least one other IMU configured to be positioned on a base of the vehicle, and configured to generate other measurement signals. The position estimation system includes an estimation unit to estimate a position of the end effector of the vehicle based at least in part on the measurement signals and the other measurement signals, wherein the estimation unit is configured to perform an estimation method that removes an influence of terrain-induced vibrations and terrain slope in the measurement signals based on the other measurement signals.
