I'm making a robot which is going to have a holonomic mecanum drive. The doubt that I'm having is that should I use rotary encoders for doing so.
The bot will be manually controlled so would it be possible for me to ignore the rotary encoders?


The thing is that I need to decide whether or not I'll be using motors with rotary encoders in my robot.
What I'm thinking:
Is it really necessary for me to use rotary encoders for implementing holonomic drive? I know that holonomic motion is attained through the appropriate vector sum of velocities generated by the motors. But since the bot is going to be manually controlled, can't I ignore the accuracy of the motion(by not using rotary encoders) as the controlling human might himself be managing those errors simply by seeing the bot's motion.

  • $\begingroup$ I'm afraid that it is not clear what you are asking. We prefer practical, answerable questions based on actual problems that you face, so it's a good idea to include details of what you want to achieve, what you tried, what you saw & what you expected to see. Please take a look at How to Ask & tour for more information on how stack exchange works and work through the Robotics question checklist to edit your question to make it clearer. $\endgroup$ – Mark Booth Jan 27 '20 at 15:41
  • $\begingroup$ @MarkBooth I have clarified the question a bit. Please have a look. $\endgroup$ – Utkarsh Verma Jan 29 '20 at 1:12
  • $\begingroup$ It would be better to have a single question rather than an unclear question followed by a clarification. I'll re-open the question, but I think it would be more likely to attract answers if you improved it further. $\endgroup$ – Mark Booth Jan 29 '20 at 9:03
