This is a great robotic kit for teens and adults. Before starting your build make sure all the parts are in the box.  The download link to the tutorial and code is on the box as there is no paper tutorial manual included in the box.  The code you will use is Python and this is an excellent code to learn as it is popular.  Assembly and programming are not for the faint of heart, especially for beginners.  The secret is to take your time building the robotic arm and learning how to use Python code.  Once you get it you will want to learn more and this kit gives you that opportunity.  This robotic arm was developed based on Raspberry Pi and is compatible with Raspberry Pi 4B/3B/3B+/3A+.  Eventually, you will get to the point where you want to purchase the not included Raspberry Pi circuit board.  A Raspberry Pi board is not cheap and costs between $100 and $160 dollars. A Raspberry Pi board is referred to as a Single Board Computer because an entire computer is squeezed into a single small circuit board.  The Raspberry Pi board will give this robotic arm the capacity to do a lot more and the Raspberry Pi board will give you a chance to learn how to program.  This is a great introduction to Robotics and there is plenty of growth in the future of robotics employment.
