Rubik’s cube solver based on AVR

Rubik’s cube solver based on AVR
This project utilizes two claws, each actuated by just two servo motors. Although program is written with wxWidgets (C++) library, it won’t compile under Windows because the system calls in serial communication part, thought if you remove it, it should build with no hassle. The thinking is done by a PC which calculates the necessary moves ...

Robot Plays Pool – ARpool

Robot Plays Pool - ARpool
This is a pool playing robot – the ARPool, an augmented reality system for teaching the science of pool. The Deep Green robot was created with the purpose of playing a flawless game, allowing it to beat even the most skilled human players. A ceiling-mounted Canon 350D tracks the position of all of the balls, in addition to another cue-mounted cam ...

Quadruped Robot runs on Rough Terrain – LittleDog

Quadruped Robot runs on Rough Terrain - LittleDog
Walking turns out to be a challenging problem because the system is under-actuated. There is limited or no actuation between each foot and the ground, unlike robotic arm manipulators where the base of the system is rigidly attached to some immobile or heavy base, and an actuator at this base (and any other joints) allows ...

How to build a constant current/power electrical load

How to build a constant current/power electrical load
Kerry Wong built a DIY constant current/constant power electronic load. One of the features a lot of commercial electronic loads has in common is the ability to sink constant power. Constant power would come in handy when measuring battery capacities (Wh) or testing power supplies for instance. To accommodate this, she decided to use an Arduino (ATmega328p) microcontroller. This ...

Multicopter Quadcopter Flight Control Hardware and Software

Here we compile all the flight controller software and hardware on the market. All with different prices and performance. Firmware options: Ardupilot Mega (which contains ArduPlane and ArduCopter among other autonomous derivatives) Multiwii which is a derivative of Arducopter MegapirateNG which is a PORT of Arducopter for the Crius board ArduplaneNG which is a PORT ...

Arduino Solar Charge Controller

Arduino Solar Charge Controller
Julian Ilett demonstrates his Arduino Solar Charge Controller. The new voltage and current sensors on the battery side mean that Watts in and Watts out can be measured and an efficiency percentage calculated. He has mounted all of his Arduino modules to a piece of wood to keep everything nice and neat. High efficiency values (96% – 97%) ...
