I’m preparing a simple technical graduation report about wheeled robot and have put a sequence of secondary titles starting from:
Types of robots in general
Criteria of choosing a robot
Choosing a robot for this project
Wheeled Robot
Types of Wheeled Robot
Basic parts of Wheeled Robot
Specs of project robot
Wheeled Robot control system
So, I’m at point 8, but I searched about the types of control system for robots and found different results, they are not the same.
I actually like the simple classification which is to define the control system for the wheeled robot into two types:
Open loop
Closed loop
Is this correct for defining types of wheeled robot control systems ?
Also I’m searching for a table comparison of these two types but I couldn’t find one.
That sounds like a very interesting report. I hope you can share it here once it is finished
So, I’m at point 8, but I searched about the types of control system for robots and found different results, they are not the same.
I can imagine. First you would have to specify what you mean by control system, as you could refer to the system used to control the wheels or the method you use to operate the robot either by a direct or wireless connection.
Perhaps this paragraph can explain more about what I mean: “A good example of this is a sophisticated underwater robot; a human controls the basic movements of the robot while an on-board processor measures and reacts to underwater currents in order to keep the robot in the same position without drifting”
So you could be referring either to the method used so the human can control the robot or the system used so that the robot can maintain the desired position.
I actually like the simple classification which is to define the control system for the wheeled robot into two types:
Open loop
Closed loop
What you found is correct and applies not only to wheeled robots but also to any control system. The main difference between the two control methods you mentioned is that the closed-loop system has feedback so it has the ability to self-correct while the open-loop system doesn’t.
This page explains closed-loop control systems and also mentions the most known types (P, PI and PID)
And in case you are also interested in including what I mentioned earlier, this may help you
Actually the report is in Arabic and I’m doing it as a reference report for diploma program in electronics.
About the report chapters and titles inside chapters, as a mentioned before:
Report title: Controlling wheeled robot with ir remote 1. Introduction: just simple introduction about robots in life 2. Theoretical background: 3 lines about robots broad applications 2.1. Types of robots: simple table containing the following types
with images: stationary, wheeled, legged, … etc. 2.2. Robot selection criteria: simple table about the main criteria
of choosing a robot. 2.3.Choose the type of robot for this project: some points about
referring to websites and eBooks for learning about robots. 2.4. Wheeled Robot: some introduction about this type of robots 2.5. Types of wheel robots: simple table about 8 types of wheeled
robots with pictures for each type 2.6. The main parts of the wheel robot: also simple table about
the main parts of this type with a picture for each part and
brief description 2.7. Robot specifications for the project: table of the key points
for the wanted robot in this project, or just buy one that fits the
specification. 2.8. Robot control: this is the part that I posted this thread for, because I found different results about controlling the robots and of course because robotics is a very broad subject, so some websites describe it in terms of whether it’s closed or open loop, some websites put it in terms of Artificial Intelligence which is a more complicated route to go for, and other sources also put the types of robots control in different classification.
I preferred the open closed loop route because it’s more simple and obvious.
And that’s it, here I would finish the theoretical background.
Next chapters about parts, diagrams, simulation, code and finally the results and conclusion chapter.
