Yes, a state matrix with zero rows and/or columns makes sense and is viable. It typically signify pure integrators in the system. In the example you give, $$ \dot{v} = -\frac{b}{m} v +\frac{1}{m} u $$ where $v$ is the speed, $u$ is the externally applied force, and $bv$ is some viscous damping force. Now if the viscous damping coefficient is zero (no ...

How do self-driving bots usually deal with transient objects, e.g., parked cars on the side of roads when they can come and go? No. In most of the open-source slams, dynamic objects are ignored which means they are just mapped as a stationary object. But there are few papers that deal with this in the way you think. These aren't moving objects at the time ...

You can use both! ROS nodes can be written in python. I'm doing a similar project and the reusability of ros code is a nice thing to have in mind. ROS also have many things already implemented (even that you want to build everything from scratch). The message types of ROS will also provide an easier to integrate application, for future projects and ...

What you are describing seems a lot like reinforcement learning, and yes, it works well for this sort of scenario. It is a popular enough approach that you should be able to find starter code in whatever language you prefer. This paper looks like it could be interesting for you. Basic set-up Typically the way the problem is set up is that we want to find a ...

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 ...

High level path planning is present in any navigation system. You can select a goal and a start position (or your current position) and a (drivable) path will be planned by any navigation system, incl. google maps. Tesla cars use a neural network based control system. Video and radar feeds are combined and a semantic segmented map of the environment is ...

Tom Sheridan from MIT used to say (I am paraphrasing from 25 years ago so I am sure to have some of this wrong) that robots which operate only in free space should update around 10 Hz; if they interact with environmental impedances then they should update around 100 Hz; if they have to go from free space to hard contact with a stiff environment, then at ...

First Simulators available like Gazebo, Yes there are many simulators, You can check v-rep (free) or whebots or matlab (non-free) for example. What is the difference between a pure software simulation and a real world (say RC) scale model simulation? The pure simulation don't count noise and non-accurate parameters you use For example when you specify ...
