Fun target shooting with Arduino driven target rig

If you like shooting, then you need proper and not monotonic target system. Shooting cans may become boring and too engaging when you need to set things up before practicing. Bob decided to make things more easier with Atmega168 based target rig, where he placed several servo motors on 3D printed structure covered by steel angle for protecting sensitive parts.

Arduino on target structure is equipped with Xbee for remote control. It can work in several different modes like single target, dual target mode with random patterns. From there you can thing of many ways what targets you attach to servo motors – color circles, faces, that vary in size and so on.

Atmega168 controlled home made Iron Man suit

Well Atmega168 cannot match J.A.R.V.I.S but can help to make some cool effects. Daniel has shared his home built Iron Man suit which features Atmega168 microcontroller. It controls Visor servo and Visor Eye LEDs. It also monitors visor up/down switch.

Probably the biggest work here is the suit itself. I must say that results are great. It really looks convincing. Why not keep upgrading the suit with more features to make it unbeatable.

Smart Robot with telepresence have PIC and AVR on-board

Telepresence robot may have many usages starting from fun exploration and ending with rescue missions in narrow spaces. rwb have posted thorough description of his project. Robot platform is actually a pretty complex system built of several nodes including PIC (PIC16F1829) based Master controller, AVR (Atmega168) motor controller, wireless VGA camera, blue-tooth module and robot platform base. Each module talks to each other by using one of several interfaces. For instance PIC and AVR boards talk through I2C bus, while Bluetooth module is interfaced through UART interface.

The only camera works on its own – it transmits data wireless to USB based receiver. Robot motion is controlled by using several sensors including optical wheel, and infrared range sensor. Speaking of camera it can be rotated with servo motor which is controlled with AVR based motor control board. Robot can be controlled with any device that has blue-tooth enabled. For instance from Android device using terminal. For more smooth operations there is an MS Visual Studio2012 Express control software build where robot can be moved with buttons including camera rotation and other small things.

Parrot buggy ride

This buggy is really fun way of keeping parrot busy all day. It’ small four wheel platform with a place for bird to sit and simple joystick control where parrot can move buggy in all direction with beak.

From technical point of view it is not only a joystick controllable drive. It also has some intelligence which takes in to action once bird is taken away. Buggy finds a way to the docking station. Docking station consists of two colorful spheres that are captured with camera. Algorithm process the image and gives command to align buggy so that spheres were aligned. Of course there are some electronics working to make this happen. Firs of all the brain. It is a Beagle board which takes care of camera, wireless comm and giving commands to motor. Lower level electronics like motors and sensors are controlled by pair of Atmega168 microcontrollers. I think any trained domestic animal would find such buggy to be fun to ride.
