2 DOF Serial Flexible Joint
This product is no longer available.
The 2DOF Serial Flexible Joint is a simplified model of a robotic arm in which the joints are designed as to exhibit visible harmonics during accelerations, while the links are rigid in comparison.
Product Details
This system consists of two DC motors each driving harmonic gearboxes in a two-bar serial linkage. The primary link is coupled to the first drive by means of a flexible joint. It carries at its end the second harmonic drive which is coupled to the second rigid link via another flexible joint. Both motors and both flexible joints are instrumented with quadrature optical encoders. The Multi-Input Multi-Output (MIMO) system is supplied with a decoupled state-feedback controller reducing flexibility-caused oscillations as well as link-coupling effects.
- Fully compatible with LabVIEW and MATLAB/Simulink
- High-resolution encoders to sense both position and joint deflection
- Interchangeable set of springs for variable torsional spring rate
- Open architecture design for maximum flexibility
