Class Goal: High Accuracy Motion Correcting 4-Wheel Robot Designed to Follow an Exact Path Without the Use of Reflectance Sensoring.
The robot was allowed to only use hall-effect sensor encoders to correct for distance traveled which brought up many practical challenges but it was a huge success nonetheless! See below:
Features:
Rechargeable 7.4V Nominal Voltage with 2 18650 LiPo batteries in series resulting in a total power capacity of of roughly 14Wh.
Arduino Nano Board with ATMEGA4809 MCU
PID control for motor speed with Hall Effect Sensor Encoders in negative feedback
Power Mosfet H-Bridge driving 4 Brushed DC motors
Infrared receiver elevated on custom 3D printed mount
Ultrasonic crash detection on front of robot
Crash warning buzzer
Emergency kill switch
Lab 4B - Group 31.pdfIMG_3275.movAs an added challenge, our group added infrared remote control and ultrasonic crash detection and avoidance. We were interested initially in creating our own remote but didn't have time to contend with the challenge posed by inverse-square law and so implemented a COTS IR Remote. See below.
