is the LM628/9 the best way to control a position of a dc motor ?
hiwell,i work with my team for build a robot it's not the first time ,in the last time we worked with servomotors but the robot can't walk in the right line, i want to use LM628/9 to control a dc motor for the wheels and about the skills of my team we control a dc motor with pic16f877 and h-bridge (L293) a servomotor with pic16f877 and a stepper motor a ultrasonic sensor and the direction of the robot always with the same pic 16f877 and we have a genius of mechanic in our groupe ,me i'm just a begginerthe best tool for making a hole? you can ask women ,they know more than me about holes
if you talk about the motor ,i don't have it so i can't give you the specs of the motor ,
i need to control the position of the wheels with minimum of error so i thought i can use LM629 with dc motor
I know I am a beginner but what I have to do, buy a motor and a LM629 and do some practical experience without knowing if this component is right for me or not
hi thank you soeren for your help ,I read your answers but I didn't understand your point well,i think i have no choice
..the parameters of the motor, the work that you want it to do, how precise position control you need and your skill level.."
I am trying to decide what kind of encoder to choose for my robot. I am experienced with electronics repair and maintenance, but have almost no experience in electrical engineering. I do have a good background in electronics though and am an experienced programmer. I likewise have no mechanical engineering experience, but am mechanically inclined. This will be my first robot and price is a concern so I would like to do this as economically as possible. I am using an Axon II microcontroller, and will be using two Futaba S3003 servos for a differential drive robot. I am not certain of what would be a reasonable amount of precision but I would like to design and traverse simplistic mazes that are about 10' x 10' square with 8" pathways. My robot is about 4 inches wide. This gives me about 2" between my robot and the walls on either side. So to drive the full distance of the field without hitting a wall I would need no more than + or - 1.5" for every 10' of travel.
