Power supply circuit: Voltage regulator converter from 7.2 V to 5V and 6V
Problem: Need a constant 5V supply with enough capacity for robot or Raspberry Pi. This needs to be regulated. Consideration 1: 7.2V Ni-MH battery with at least 3000 miliAmper per hour (mAh), but if voltage is too big it will burn the Pi! Consideration 2: 4 x 1.2V Rechargeable AA battery that will supply 4.8V, this won’t…
Robot Project Day 0 – Procurement and Preparation
Robot Project Index Design Considerations First we need to define the purpose of having this robot, besides for showing it off to your parents and friends. Then we need to decide what the robot can do. Set up a GOAL. A goal for the robot must be SMART. Specific Measurable…
How to Build a Raspberry Pi Robot in 10 Days
One of the most popular topics on the Raspberry Pi is to build your own robots. It is in every child’s (and lots of adult) dream to be able to run and control a robot. The Raspberry Pi computer is light enough to lift and carry it self up on…
Servo Manual Control Without Arduino Servo Library on Raspberry Pi and Gertboard
Arduino Servo library Servo.h despite its simplicity often creates timer conflicts with other PWM pins. In our lab experiment, we found that when we attach servo on Pin 11, PWM capability on at least one of the other pins gets disabled, e.g. the right wheel of the rover attached to Pin 3…
