Background
I have a car-like mobile robot (4 wheels, where the forward ones are steering wheels) and I want to estimate its pose and velocity assuming 2D planar motion. I'm trying to solve this ...

I'm reading from Astrom & Murray (2008)'s Feedback Systems: An introduction for scientists and engineers about the difference between feedback and feedforward. The book states:
Feedback is ...

How are the brushless motors in a gimbal assembly designed?
Obviously it doesn't need continual rotation, but it does need accurate control of precise position. I've noticed that the motors in my ...

I am doing a project, to draw images provided using robotic arm. Initially edge detection is done on image to be drawn and coordinate value is obtained as (x,y).
How to calculate 3 joint angles ...

What are the main differences between motion planning and path planning?
Imagine that the objective of the algorithm is to find a path between the humanoid soccer playing robot and the ball which ...

I have seen waveforms for driving a brushless motor.
I guess this is the waveform used for the simpler block commutation. But if I want to do sinusoidal waveforms, what does the PWM signal look like ...
