Hi.
I want to build some kind of a robot butler.
So i have a lot of questions at this early stage.
I have a base with 2 wheelchairmotors incl. gearings and rubberwheels, that I control with analog output on my Siemens plc 314C-2PtP over 2 x 24Volt 20Amp H bridge motor drives. I can control the direction and speed.
If i want to do some accurate positioning with this robot, I’m thinking of adding some encoders. I don’t have much experience in encoders, nor how to program them, so any advice or tip about this would be highly appreciated. I guess my 314C-2PtP can be useful.
I’m hoping, that I somehow can get this robot, to repeat a earlier driven route, but I guess that friction between the wheels and the floors will make it very difficult. I have been lookin at some linetracking sensors, but I’m hoping I can achieve this without these sensors.
I think that, if I add some distance sensors, and I somehow save the measured distances, when moving around in the house, then maybe I can use them, in the plc-program, helping getting the same route repeated.
I also have some powerful 24 Vdc actuators from Linak, (capable of lifting more than 200 pounds) that I could use for the arms of the robot.
My plc only has 2 analog outputs, and I’m wondering what would be the smartest thing to do.
Should i get some more analog outputs and motor drives for the arms, or is there a smarter way ?
Regarding the hand (or hands) of the robot, I believe it is gonna be difficult, because I want the hand to be able to grip, turn and wrist, so there is gonna be some mechanical work there. Any suggestions for the motors for the hands ? (I’m thinking of servomotors, but I dont know if they are powerful enough, and also here I don’t have much experience in programming servos).
