The answer is 'yes'.
A more detailed answer likely depends on how you define "robotics". But generally, robotics applications are considered to require a very broad spectrum of knowledge. So while most robotics includes some form of mechanical function, you could easily specialize in artificial intelligence, microcontroller design, or any number of ...

Stage and Gazebo are open source 2D and 3D simulators respectively. They are created and maintained by the Player project. They are very easy to use and have a lot of pre-built maps and robots. Depending on the experience of your audience you may need to do a bit of the heavy lifting (i.e. building configuration files and the main classes).
They have a ...

In general you don't need to learn assembly to be able to program a microcontroller. As long as you know C, it's enough for you.
Knowledge of assembly of course would help. Specifically, it would help in writing optimized code (or rather, not writing stupid code) as well as having a good estimate of how fast or slow a piece of code could be. Sometimes in ...

This is one of those "open-ended" questions that the moderator doesn't like. So I'm going to leave you with some short, general answers. These are based on over 20 years in industry designing various bits of hardware and software for embedded systems:
Learning enough about microprocessors so that assembly language programming comes naturally will be a big ...

May be it is a bit pricy (CHF 75) but I still suggest Colobot. It is a nice, almost game-like environment where robots need to help humans to make a space base habitable. Robots are programmed by the kids while increasingly complex tasks are performed. The program teaches the fundamentals of programming in a goal-oriented, funny way.

Working in robotics doesn't mean that you must understand (or enjoy) all the relevant disciplines. It simply means that you must understand that you are one part of a team that produces a robotic system. On the other hand, what skills you have will determine which teams will find you valuable as a member -- smaller teams require everyone to bring multiple ...

For most applications, I think the calculation you describe is good enough when selecting hardware. You want your arm to be able to have some lift capacity at the worst case, which is when the arm is fully extended. Note that you should also take into account the weight of the arm itself which is typically non-negligible.
That being said, yes, there are ...

I think this is a great question.
The two basic options are make it yourself or have someone else make it. EDIT: check the bottom for a third option...
Make it yourself
To make it yourself you need to choose a material and manufacturing process for the part, then acquire the material and skills needed. (Usually people select a process they know how to do ...

If you make a career of robotics, you will come in contact with a lot of languages, a lot of libraries, and a lot of systems.
The more you know about the fundamentals, the easier it will be to adjust to something new. Likewise, if you focus your learning on whatever project or context is relevant to you at any given moment, it's more likely to stick with ...

It is usually a combination of 2 different pieces software. Generally a higher level software which implements most of your autonomy, advanced navigation algorithms, and a lower level software which deals with interfacing the motors, a simple state estimator, and accepts waypoint commands.
Most common is ROS for the higher level software, and a PX4 for lower ...

I think you are mixing the idea of BEAM robotics (why that, I prefer to not use this term), with analog electronics.
Analog circuits are in major applications more fast than a micro processed one, that have a clock to process instructions. The "problem" with analogs is in part with noise, but early computers are made analog, operational amplifiers are made ...

If we are defining BEAM robots as ones that do not use microprocessors, and only use analog circuits, then yes I think it is possible, but not practical.
A microprocessor is essentially a programmable circuit, and if we define what we want our robot to do, then we should be able to program the hardware (by building the proper circuit) without needing a ...

I don't think there is any "must" for you task. In turn, it depends on what your robot platform is. In the context of embedded systems, MATLAB could be cumbersome.
I don't know what your robot system is like, but maybe this article based on ROS and Sphinx is a good starting point?
Also, for the purpose of understanding speech recognition technologies, the ...

The major disadvantage of assembly language is that it is different for each processor that you use. Therefore there is a big learning curve whenever you change processor.
Clearly, if you only ever plan on using a single processor (or family of processors) then this is less of an issue; however, life is rarely that simple.
Equally, assembler allows you to ...

Have you considered modeling the robot in a simulator? V-REP is new and quite good, having lots of examples robots from other famous projects. Gazebo is another popular one that is usually used with ROS (although V-REP also has ROS support). Both run on linux and are open-source.

The Actin toolkit is the only one I know of that sounds like what you want.
It integrates with SolidWorks to provide the kind of analysis you are talking about.
Other people may know of other similar tools though.

The short answer is that I don't think a good standardized motion file format exists and I don't think there are any good generic wysiwyg robot posing tools. Some level of custom programming is going to be required.
RE: Standard file formats for robot motion
Collada is meant as a standardized 3D data interchange file format, and it has support for storing ...

Microsoft robotics is FREE and includes a simulator. It is not exactly the easiest environment in the world, however it IS robust and appropriate to real robotics. I think with some teacher involvement to set things up beforehand, it could be usable. There is a simulator 'package' for LEGO, Neato and some other robots, and they can be programmed in C# or a ...

I believe the EN 61508 is the most important one from the software point of view.
But it is not only valid for robots. This is one of the most important standard for industrial development. It defines the safety of a system, that it has to be free of "unjustifyable risks"
There are all the requirements for:
- rts
- redundancy (including redundant software)...

Having only the proportional term of the PID regulator will most definitely leave you with oscillations. If you think about it, it's quite similar to a linear harmonic oscillator F=k*x (formula for spring motion). Adding a derivative term should damp out those oscillations. If after waiting for the system to stabilize you see it stabilized with some offset ...

For your first example, Max-Weight = Torque/arm-length. Going beyond that, there are several software applications and API's out there that can be a big help for these kinds of calculations (matlab or pyODE to name a couple), but they will be pretty useless without a decent understanding of what you are computing. A good resource to learn about the mechanics ...

web based robotic simulator will be a good project. You can do simulators like gazebo and morse

most people told me about using registers and memory addresses to talk to devices
Shortly, that is the correct answer - if you are interested how software will (ultimately) talk to hardware. How hardware can have an impact on software, things get a lot more complicated.
If you want to understand deeply how things happen, you should study how micro-...

There are quite a lot options for this, each with different features, strengths and weaknesses. A few examples:
Gazebo (as mentioned by edwinem): very well known in the robotics community, some would say it's a little bit dated
Microsoft Airsim (also mentioned by edwinem): originally developed for autonomous drones and autonomous driving, uses the unreal ...

RobotC has a simulator available, although both are products at some costs. However, they are very geared towards younger students and education. This would be the easiest, and most appropriate route if costs are not a blocking factor (around \$100 per license for both for single user, \$300 for 6 users, \$600 for 30 users).
If you buy the student version ...

Microsoft Robotics uses a protocol called Decentralized Software Services Protocol (DSSP) and they released the specs under a license that allows anyone to implement it in any language. The DSSP protocol is totally compatible with current web standards and I think it would be a great idea to implement it in JavaScript and NodeJS. That can make it possible ...

To offer an answer that (specifically) addresses the question, as I understand it, the RaspberryPi offers (either as part of the standard Pi distros, as add-ons or compilable from source) pretty much anything and everything that the Linux operating system provides.
However, for those that are not part of the distro (or from the repositories) there are ...

V-Rep (Virtual Robot Experimentation Platform) seems to be quite broad in the kinds of simulations that it can do. It is free for educational purposes and comes with a wide range of tools. You can take a look at this YouTube video for a demo.

You can use SolidWorks, ADAMS or CATIA software.
You can design your platform and analyses or make formula for that with these software s.

Robotics is by definition a subject rooted in mechanics and if you "hate" this subject then surely there will always be an large part of this industry that you "hate". So I would suggest you review either:
a. What you mean by "I hate mechanics" or "the mechanical side"
b. Understand what you like about Robotics because in the end all of the work is ...
