One widely used platform utilizes a six degree of freedom manipulator attached to quadcoper or octocopter, to sample a tree leaf by maintaining the system in a hover while the arm pulls the leaf for a sample.

The ability for aerial manipulators to stay aloft while interacting with dynamic environments is critical for successfully in situ data acquisition methods in arboreal environments. The performance of proposed control laws is confirmed by simulations. The control approach is applied on a two-link elbow robotic manipulator which is driven by permanent magnet dc motors and can be applied on up to n-links robotic ma-nipulators, too.

Modifications are used to derive a control law which is free of velocity terms and can pass the singular points into task space. Although, for overcoming the uncer-tainties in actuator dynamics, robot dynamics and kinematics is a major advantage, the proposed control cannot pass the singular points in task space and there will be malfunc-tions when it is applied on the practical implementation. It is proven that the closed loop system has global uniform ultimate boundedness stability. A robust controller is designed based on Lyapunov method, using dynamic delay, backstepping method and unknown bounds of uncertainties.
