Dynamic-Movement-Primitives-and-Imitation-Learning-Robotics

Dynamic movement primitives (DMPs) are a method of trajectory control/planning from Stefan Schaal’s lab. Complex movements have long been thought to be composed of sets of primitive action ‘building blocks’ executed in sequence and \ or in parallel, and DMPs are a proposed mathematical formalization of these primitives. The difference between DMPs and previously proposed building blocks is that each DMP is a nonlinear dynamical system. The basic idea is that you take a dynamical system with well specified, stable behavior and add another term that makes it follow some interesting trajectory as it goes about its business. The DMP differential equations (Transformation System, Canonical System, Non-linear Function) realize a general way of generating point-to-point movements. Imitation learning using linear regression is performed to compute the weight factor W from a demonstrated trajectory dataset, given by a teacher. The quality of the imitation is evaluated by comparing the training data with the data generated by the DMP.

RF--Harmonics-Intermodulation-Products-Calculator

The purpose of this mini project is to design a “calculator” of Harmonic and Intermodulation components that are generated due to non-linearities of the RF receiver (Particularly Amplifiers). It will accept 2 OR 3 input frequencies (in MHz) and generate the Harmonic and IM components separately as outputs. The repeated results both within and across orders are eliminated. Everything is summarized in a way that allows one to determine which transmitters are the most likely offenders. Phantom results are also eliminated.
