### Cartesian Impedance control Damping Design (Double Diagonalization)

A hint towards what the answer is given in the paper. Namely, one can use the generalized eigenvalue decomposition, which in this case can be formulated as finding eigenvalues $\lambda \in \mathbb{R}$ ...

### Why Does an Exponential Make ANYTHING a Probability Distribution

I believe it's because you're essentially constructing an exponential distribution which has the form Because your loss function will always be >= 0, you form a valid PDF (valid in that it ...

### Difference between Degrees of Freedom (DOF) and Degrees of Motion (DOM)

The way you are describing it, DOM is the number of independent dimensions in $\vec q$. DOF is the number of independent dimensions in $\vec x$. In practice, a robotics engineer will use DOF to ...

### Does a controlling system need to be more complex than the system being controlled?

Complexity is not a word that's used in control theory but I think I know what you mean. The short answer would be no. Complexity in systems to be controlled is usually looked at in terms of how many ...

### What algorithm should I implement to program a room cleaning robot?

I'm not sure if you still need it, but for those who happened to google for this thread, I have made one simple version of the algorithm. Basically, it tries to build the map of the area while it ...

### What is exact model of haptic interface system in the paper "Time-Domain Passivity Control of Haptic Interfaces"?

It's usually best to contact the author directly if you have a specific question about a specific paper. The simulations are there only to illustrate the principal of the passivity observer and ...

### Is Fuzzy logic applicable for robotics research

I would like to mention that Fuzzy logic is still an active control system used in many industry applications. In garbage fired power plants, concrete aggregate firing, hydraulics, and the control ...

### Is Fuzzy logic applicable for robotics research

Short answer: Fuzzy logic (FL) isn't applicable for robotics research, The long answer is, that in the 1980s as part of the fifth computer generation fuzzy logic was researched in Japan with the ...

### Is Fuzzy logic applicable for robotics research

Fuzzy logic is definitely used in many of the control systems including but not limited to robotics. See this paper for an example: https://pdfs.semanticscholar.org/b9a7/...

### Does a controlling system need to be more complex than the system being controlled?

Approaching your question in a broader perspective... I believe that a good answer to it could be provided by Ashby's Law of Requisite Variety - postulated as follows: When the variety or complexity ...

### What algorithm should I implement to program a room cleaning robot?

Looking at the simpler problem that you were asked - a rectangular room, with no obstacles and clean every part at least once. The solution is to find a corner of the room, and finding a corner won't ...
