How to Increase Line Follower Robot Speed: 100rpm Stepper vs DC Motor?

318 10

Best answers

How can I increase the speed of my line follower robot and reduce turning delay; can I replace 100rpm stepper motors with DC motors?

Yes, you can try an ordinary/DC motor, but it may not be preferable if the arena has sharp turns [#21661253][#21661257] The slowdown seems to come from your turning routine on the 8051, where you added fixed delays between straight motion and turns, so reducing or redesigning that delay logic should help [#21661254][#21661255] One suggestion was to use PWM to control motor speed [#21661257] Another was to add smarter control such as fuzzy logic for the line-following decisions [#21661256]

i am taking part in linefollower robotics event.
i made my robot and its working properly but problem is that
i used 100rpm stepper motor and during turn to left or right there is some delay and during turn it also take some time so overall delay is more, so i want to increase speed of robot.
can any new suggestion to increase speed?
can i use DC motor to increase it?

can you elaborate more on what are you using like which micro controller, motor controller and the circuit detail's

this depend's upon arena if it has sharp turn's dc motor's will not be preferable but though you can use it by some change's in circuit

i am using 8051 controller and i put some delay between general motion and for turn.

ok
ya problem is only during turn during normal way its run fast but in turn it lstt its speed and its take more time.

Have you ever heard of Fuzzy logic and did you incorperate this into your design if so can we see a flow chart

You can use an ordinary motor I think what i would have done is use servo,s myself and PWM to control motor speed thats a suggestion

Recomended bed time stories John Iovine " Pic Robotocs !" If you fancy encounters of the fourth kind Excellent book on how to and why

thank you
but i made my robot using 8051 controller and you sent file is pic controller
but i will try to learn servo motor from that

Topic summary

A line follower robot using a 100rpm stepper motor experiences delays during turning maneuvers, causing overall speed reduction. The robot is controlled by an 8051 microcontroller with programmed delays between general motion and turns. Suggestions to increase speed include switching to DC motors, though their suitability depends on the arena layout, especially if sharp turns are involved. Alternatives such as servo motors combined with PWM control for speed modulation were recommended. Incorporating fuzzy logic for improved control was also proposed. References to PIC microcontroller-based designs and related literature were shared for further learning, despite the original design using an 8051 controller.
