The approach is the right beginning. The term for it is dead reckoning. It has some problems regarding its precision. Next steps in increasing precision would be sensor adding optical flow or other sources for distance travelled some using sensor fusion technique. You do not have a redundancy problem. If you use the same sensor signal and transform it into ...

This project does exactly that on an RC car. The author is a top competitor in the DIYRobocars community; it's the blue car in this video. He uses tachometry from the brushless motor, an IMU and visual odometry for localization. I don't know the code well enough to point you to any specific file.

Let's suppose you have a required (continuous) trajectory in the form of an equation that you want to follow, for example take a straight line (whose equation is y=2x+5), you can break it down into discrete points and generate a velocity profile out of this trajectory, the calculated velocity profile could be fed to inverse kinematic equations [1] of robot (...

Given that you are using 2 dc motors, I'm guessing you are using a differential drive configuration. Your intuition about the algorithm is good. The encoders on the motors along with some physical/mechanical measurements (wheel radius/circumference and wheel base) are used as input to a kinematic model, in this case the unicycle model. Using this, you can ...

Axial (or thrust) force refers to the force applied along the axis of rotation, not the load that is applied to the motor. (This load would be a torque, anyways... not a force). Probably fine for a tractor, not fine for a F1 racecar. This is a question you need to answer based on your application. There might be. You can adapt drills with anti-backdrive pins ...

My bet is on a PMSM not a stepper, but that cannot be determined from an image. A non-back-driveable mechanism is advantageous, and can reduce the steady state power consumption of a system. It does not necessarily have to be a worm-gear. Regarding shock-absorbers..well a few things have to be considered: Shock absorbers are normally tuned to filter out ...
