Motion Robotics
Please everyone, help me I'm in big trouble. I want to build a Robotic Arm as my engineering project.?
robotic arm is to be operated ps / 2 ball mouse (not optical). Now I can not get the sense of clockwise and counterclockwise motion how detected an infrared sensor on a single axis, so that very few modifications I may put it into practice. I have to google a lot and came back disappointed. please someone help me. will also be appriciated if you show me some information with respect to normal production by any PS / 2 mouse (ball or operated optically) when 1) Fixed 2) moves to the left and right 3) moves up and down.also mention the word size. thanks in advance 4 ur time spending in response.
Yes the point is that it takes two sensors to indicate the direction. It may well be contained in one package, illuminated by a source to go alone, but requires two sensors for each axis. As you turn the slotted disc, each slot in turn enable the IR source to illuminate a sensor first, then the other. The relative phase between the two outputs indicates the direction sensor. (And often indicates the speed of movement.) This is then processed by the chip in the mouse and turns into a serial data stream that can be interpreted by the computer. Dealing with the "terms of electronics would be a complicated affair, especially if you just hoping to cannibalize cheap mouse and connect / 2 connector PS in a box of tricks. If you are using a computer to control the problem, probably the 'computer' science and the solution to write a control program using the original PS / 2 port subroutine calls. Even then, I suspect that a system based on the count of incremental changes position would be error prone position – a minor vibration or odd number result in a cumulative loss in absolute position error. That's not a problem with a mouse, because it is part of a hand – eye closed feedback loop system, but an arm of the robot? Are you committed to this type of solution? My first thought would have been boring old knobs or displacement transducers in the A / D converters Good luck with your project.
