obstacle avoiding robot using pic16f877a code

One of the biggest challenges in building your own robot is controlling its motors. You can find new or surplus
motors and gearboxes in many places, and low-cost microcontrollers and books on how to use them abound.
However, microcontrollers cannot directly drive DC motors, leaving robotics beginners with the possibly
overwhelming challenge of building their own motor controller. This task is even more complicated if the motors
require bidirectional operation and speed control. This project demonstrates how easy it is to make a simple robot controller using the Pololu micro dual serial motor controller [http://pololucatalog/product/410] with a Microchip[http://microchip] PIC16F628 microcontroller. We then use the circuit with the Pololu robot chassis[http://pololucatalog/product/250] to create a small, obstacle-avoiding robot that can serve as a starting point for more advanced projects. The low-voltage operation of the motor controller allows a small, 3.6 V cordless telephone battery pack to power the entire robot. Since the motor controller only requires two of the PIC s 13 I/O lines, there is plenty of opportunity for expansion.

Abstract

The purpose of this project is to develop a mobile robot with an obstacle avoidance capability. The mobile robot will be built with an onboard sensor to get information about the surrounding environment. The mobile robot is a four wheeled robot platform. The robot has an ultrasonic sensor which is mounted in front of it to scan the front environment. The ultrasonic sensor will trigger a signal to the main controller, which is a PIC16F877A microcontroller. The direction of the mobile robot will be controlled by onestepper motor that connected to the output of PIC16F877A microcontroller. The stepper motor will change the direction of mobile robot when an obstacle is detected. The other two wheels are dc motor which is only for motion purpose. The dc motor will be only run forward without influenced by the obstacle senses by ultrasonic sensor.

Good Morning sir..
I am a degree student who want to ask about obstacle avoiding robot using PIC 16F877A coding using assembly language. For your information in my project, i'm using ultrasonic sensor but i can not display my output on LCD. i hope you can help me for ultrasonic sensor and PIC coding. hope can get your respond as soon as possible.

Thank you for your concern.

I need the code for my project.My project is to do a obstacle avoiding project using PIC16f877a microcontroller and the distance between the robot and project will be displayed on a LED board. Kindly send me the code to [email protected].
Thanks for your kindness.

hi,
can i get the code? because right now i'm doing for my course project in subject microcontroller. my lecturer give a task to do a project obstacle avoiding robot using pic16f877a. i really need your help. thank you for spent time to read my request.
