This is my mower I converted to electric. You’ll notice it doesn’t actually cut anything. That’s because I’m waiting on the 4th motor controller to arrive after frying the first three. , https://i.ytimg.com/vi/52XbgCOP_lU/hqdefault.jpg sourceContinue Reading
[STROBE WARNING!] I threw this together from an old toy’s motor, old printer’s iR sensor, pizza box and some other things, to try out the PID controller algorithm after discovering it on Wikipedia and seeing that there was pseudocode, meaning that I didn’t have to get a PhD in mathematicsContinue Reading
Closed loop PID control of a VW diesel engine with an Arduino microprocessor. Throttle actuation accomplished with a stock RC servo motor. See http://mckgyver.pbworks.com/Firewood_Processor_Governor for Arduino source code and schematics , https://i.ytimg.com/vi/v7GLQU-0Nwc/hqdefault.jpg sourceContinue Reading
An Arduino with a MegaMoto shield to drive a motor as a large RC servo. The Arduino runs the PID positioning algorithm which the MegaMoto uses to drive the motor. The motor has a 10k POT attached that feeds position values back to the Arduino. Arduino sketch here: http://code.google.com/p/megamoto-superservo/ ,Continue Reading
Adding a servo steering system the robot is able to steer very well using a compass chip. The process of testing the steering system is discussed using a control console written in Processing. The final goal – down the road aways – is to have an autonomous robot lawn mower.Continue Reading
