Hi Hassan, Thanks for your comment! We do not have video courses on robotics at the moment, I will happily pass it on to our course developers as a topic suggestion. Thanks for sharing and happy learning!
Thanks for your support! The pictures are only used in the video course and created by our graphic and animation department - we don't publish them elsewhere at the moment.
There are a few simulators available if you search for "6-axis robot simulator'. The best software simulator I have found is www.codeproject.com/articles/756070/simulator-axis-articulated-robots. However, you will need some C++ programming experience. There are many "science kits" available as well. Do a little research and you will find a lot of different options. A popular kit (may only be available in the US) is New DIY 6-Dof Robot Arm 6 Servos & Circuit Kits for 6 Axis Rotating - Walmart.com. This can be programmed with an Arduino or Raspberry PI with a little experimentation.
Meh, it would have been better to show an actual robot arm, demonstrate motions in a simulator etc. A cartoon illustration doesn't really add value here. Also, the most important bit to understand in manipulator selection is why six axis, why not 3, 4, 5 or 7? Indeed many times 6 is not the correct choice after all, it depends entirely on application, too few axes does not work and too many sacrifices money, precision, rigidity and cycle time but may save in resale value of equipment, 6 axis often being most generic is easy to repurpose after it's no longer needed on a given job. In addition, often the task is very much not as simple as lifting a box and just because something is possible mechanically, does not mean you are capable of writing software that can correctly tell the robot how to move. For example random bin picking while being mechanically trivial, remains a problem that is not completely solved despite many companies throwing uncounted millions at it.
While using a real robot arm would add a realistic note to this video, it would also be very expensive to use in this type of video. Our goal is to introduce the learner to the terminology and basic concepts behind a 6-axis robot. It is not meant to be an in-depth design guide or all-encompassing look at how robots work. The topics you brought up are valid and necessary for robot design and evaluation, but are beyond the scope of this introductory video lesson.
