Incremental Encoder Selection

Hi all Just a quick post on incremental encoders. Incremental encoders are good for speed control and can be used for position control when we have a homing routine to get absolute position, or the system is constrained to less than one rotation. One way an incremental encoder can also be an absolute encoder is if it is single turn.…

Sensor types (modalities) for robots to experience the world

Hi all There are many different sensor types that can be used on a robot, and most robots will have many different sensor types. I am going to talk about the common types and avoid some of the more application specific sensors such as environmental, radiation and chemical. When I think of sensors I divide them into two categories. You…

Motors and Feedback (encoders)

Hi all There are many types of motors and feedback methods to choose from. Which do you need? Keep reading to find out more about selecting your motor stackup. Since most field robots are DC powered I am skipping the many types of AC motors that are out there. In addition to this post you can find out all about…
