  • $\begingroup$ @jsotola like what are the components required to build this robot? $\endgroup$ Nov 26 at 17:51
  • $\begingroup$ that cannot be answered, unless all robotic arms in existence are identical $\endgroup$

  • $\begingroup$ Welcome to Robotics Pedakolimi Harish, but I'm afraid that Unbounded Design Questions are off-topic because there are many ways to solve any given design problem. We prefer practical, answerable questions based on actual problems that you face, so questions which ask for a list of approaches or a subjective recommendation on a method (for how to build something, how to accomplish something, what something is capable of, etc.) are off-topic. Please take a look at How to Ask & tour for more information on how stack exchange works. $\endgroup$

  • $\begingroup$ Typically, you also need to know the arm's link lengths and acceleration and velocity requirements before motor / gearbox selection. Just knowing the payload is not enough information. $\endgroup$
