SUMMARY

The discussion focuses on feedback mechanisms for basic robotic arms, specifically the use of motor-mounted sensors such as resolvers and encoders to determine joint articulation and position. Resolvers, while more expensive and requiring complex integration, are noted as superior to encoders for this purpose. Calibration during installation is essential to ensure accurate alignment with the arm's actual position. Participants are encouraged to explore specific robotic arm models and their associated documentation for deeper insights.

PREREQUISITES
  • Understanding of motor feedback systems, specifically resolvers and encoders.
  • Familiarity with robotic arm mechanics and kinematics.
  • Knowledge of calibration techniques for robotic systems.
  • Basic grasp of control systems in robotics.
NEXT STEPS
  • Research the differences between resolver and encoder technologies in robotic applications.
  • Study calibration methods for robotic arms to ensure accurate positioning.
  • Explore specific robotic arm models, such as those from ABB Robotics, for practical insights.
  • Learn about motor control systems and their integration with feedback mechanisms.
USEFUL FOR

Robotics enthusiasts, engineers, and students interested in the mechanics of robotic arms and feedback systems, as well as professionals involved in designing and calibrating robotic systems.

For a basic robotic arm, how does it gain feedback of where the joint articulation/position is? I'd like to start learning about that a bit more, so any resources and insights would be great.

Thanks

Typically the feedback is motor mounted - on the shaft( providing motor drive control - and arm position info) - done with Resolvers ( analog) or an encoder ( digital) - I have been out of the details on this for a while 10 years, however the resolver seems to be the better system, but more expensive, and requires more integration. But if you research these two technologies - you will learn a lot about how these are used.
Of course any motor shaft mounted system needs then to be calibrated at installation - to align with the actual arm position.
I would pick an arm - and research that. i.e. http://pergatory.mit.edu/kinematicc...abb_robotics/general/6400r product manual.pdf
