In this paper we focus on the problem of the vertical movement control and approach to control algorithm implementation for unmanned aerial vehicle (UAV), known as a quadrotor. The most important control subsystems for the VTOL (Vertical Take-Off and Landing) are the attitude stabilization and the altitude regulation. Both systems are presented in this paper. However, the vertical movement of the platform has been confined to precise operations such as taking-off and landing. These actions demand high reliability and they are very crucial for autonomous flights. The design, analysis and the validation tests have been undertaken on the experimental aerial platform.

The control of compliantly actuated anthropomimetic robots with complex and multiarticular joints, such as those developed within the ECCEROBOT project, is extremely challenging. We are approaching the problem by using a physics engine to run a highly detailed simulation of such a robot's structure and dynamic behaviour, and then searching for sequences of motor activations that will achieve particular goals. This requires the simulated robot to be situated accurately in a physics-based representation of its environment which includes the object with which it is to interact. In this paper we present our environmental sensing and modelling scheme which uses data from a single headmounted Kinect sensor to provide and locate the environmental model, and to identify and locate the target object accurately in the presence of significant motion blur.
In this paper we adopt the spring loaded inverted pendulum (SLIP) model as the mathematical framework to represent biped locomotion, but in contrast with previous studies, we redefine the conditions for valid locomoti...

This work proposes a detection method for faults that can appear in the actuators or gear transmissions of robot manipulators due to increased resistance in joint movement or mechanical jamming. It is assumed that the robot system is controlled using a computed torque-like algorithm. The fault detector is formulated as a disturbance observer and it can also isolate the location of the fault, namely in which joint of the robot the fault appears. The detector is based on a disturbance observer which is designed such that it is insensible to high frequency additive disturbances and model uncertainties. Simulation results are presented to show the applicability of the proposed fault detection method.
