After I built the tiny balancing robot using an IR sensor for stabilization, there was a comment on the youtube video about how it would be a good thing for kids to build and learn about PID controls. I thought that was a great idea, the only problem was that that tiny robot was the simplest of balancing robots. It was just an on off switch for telling the motor which way to move. There was no actual PID implementation in that system. So that got me thinking about how it would have been really cool if in one of my classes where I was learning about control theory I had a robot that actually let you see the changes in a PID system in real time. I decided to take it upon myself to create such a robot.

A beautifully designed robotic bartender capable of producing perfect drinks every time, with technology that brings people together.
Barobot is an open source device that pours cocktails by mixing alcohol, soft drinks and sodas. It holds up to 12 bottles and can pour a drink with millitary accuracy!
Barobot features over 1000 cocktail recipes or gives you the option to create your own on the fly. All can be easily accessed via our custom made application on your touchscreen or the user friendly interface on your Smartphone.
Barobots frame – made of either deep black or transparent acrylic glass, comes in either a self assembly kit or an assembled ‘plug and pour’ version. The flat-pack self assembly kit requires no advanced skills or tools (it’s great fun to put together by itself!). Barobot is also illuminated with over 100 individually controlled LEDs that might be set to a number of light-themes or even synchronised to music!

An Attiny85 IR Biped Robot by coretechrobotics.blogspot.de:
Although wheeled robots would be better for beginners I wanted to build a legged robot. Mostly because there were no continuous motors in reach and my attempt to modify a servo failed miserably.
One of the simplest solutions is a biped robot that moves as it shifts its weight. Two servos are needed for the feet and another two to move the legs to go forward or backwards. It is boring to just make the robot walk until the batteries are dead. So I decided to use infrared to receive commands.

This instructable describes a mini line follower robot that requires no microcontroller unit for control. The line sensing and steering mechanism is constructed totally using analog circuitry consisting of two OpAmps. The robot is powered by a rechargeable Lithium-ion battery. [via]

Dave looks at the open source hardware UFactory uARM 4-axis desktop robotic arm kit project available on kickstarter.
This is the first unit produced, and comes with the suction cup head and Arduino Uno board and shield controller.

The Arachnoid Mobile Platform is an open source robotics development platform used to make small autonomous moving robots. It can be either configured as a four-legged robot, or as a two wheeled robot. The PCB board holds all the electronics and mechanical components, and also serves as the chassis of the robot.

A do-it-yourself Delta Robot kit that’s fun to build, sharp to look at, and a great point of departure for your own project!
Want to make your own delta robot? Do you support the global onslaught of adorable little yellow machines? If you answered yes to either of these questions… then we have the best product to offer you!
The kit includes all of the delta’s mechanical pieces in grey and neon yellow plastic (the yellow fluoresces under black light!), all of the spacers, brackets, ball bearings, and hardware required to assemble them, and the electronic components, PCB and wire harness needed to wire it up and give the delta power.

I love robots. Normally the ones I build are quite large and wouldn’t fit in your pocket, but for a change of pace I decided I would try something small and fun! This robot is exactly that, and in fact fits inside of an altoids tin. It is inexpensive, versatile (so many different sensors can be used), and extremely entertaining. Check it out in action below! (Unfortunately I played with mine so much before I took any video I had used up my coin cell batteries and one motor started having issues, so I’m driving it with a 9V in the video)
