A novel control scheme, namely adaptive-adaptive robust (<inline-formula> <tex-math notation="LaTeX">$\text{A}^{2}\text{R}$ </tex-math></inline-formula>) control is proposed for motion control of mechanical systems. The system contains uncertainty which is bounded while the bound may be unknown. Two designs of robust controls are proposed, with the first class featuring leakage type and the second class featuring dead-zone type. Each class involves an adaptive law with the intension of mimicking the uncertainty bound. However, there exists an undetermined design parameter in the adaptive law. An upper-layer adaptive law for the determination of this design parameter is then proposed; hence rendering the adaptive-adaptive robust (<inline-formula> <tex-math notation="LaTeX">$\text{A}^{2}\text{R}$ </tex-math></inline-formula>) control. The control guarantees uniform boundedness and uniform ultimate boundedness of a resulting augmented system state, including a <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-measure which reflects how close the constraint is followed.
