Should I buy a 3-axis robot arm or a 6-axis robot arm? By the way, can you explain the reasons?
That one is completely up to you and depend on what you will be using it for. 6-axis will be more capable but probably cost more, and 3-axis will be easier to program and most likely cheaper.
Hey, thanks for the reply! So what interface is the 3-axis robot arm using to communicate?
Sorry I’m not too sure what you mean by this, there are lots of different communication protocols that you could use and depending on the safety needed. CANBUS has a level of safety to it along with a current varied supply (4-20mA, so if the circuit becomes open it trips a fault and same if it goes over). There are some premade out their oriented towards makers to hack and throw together their own spin on it
Hey Lance and Liam,
I’d be keen to see what you come up with! I’d love to see some mechatronic systems on here
Since the LCD I’m going to use has a UART serial port, it would be nice if the robotic arm also had a corresponding interface. If not I will consider using MCU for control.
I will update here as soon as I have progress.
Most microcontrollers these days have some form of UART and same with SBC’s.
