Description There are lots of designs on the Internet for DC power controllers using Pulse Width Modulation (PWM) to control the speed of a motor or power to a resistive load. Most of these use analogue methods to generate the PWM signal which in turn drives a power MOSFET or transistor. When I wanted a …
Since I finished my degree in April, I have been looking for work. The search has been slow but hopefully soon I will be making the big bucks. To fill my spare time I decided to do something with the mounds of electronics and such sitting in my room. First is to build a robot …
Background From the first robot I ever made, I have always felt that when designing the motors, wheels and drive train, it will almost always be important to know where you are – that is, to have some sort of encoder feedback. So the first robot I built used stepper motors, but I found that …
