Okay.. by common consent my simpleWalker has been dubbed flatpack walker according to hack a day. Who am I to disagree.. It got posted on hack-a-day after my first-time-ever ‘instructable‘ I posted on this topic.Read more
At the protospace fablab I made a laser-cut wood version of the simpleWalker. It took only 5 minutes on the laser cutter, instead of an hour behind the bandsaw! I used 4mm birch plywood. The robot works well (and smells like a campfire … oh well…) Again, it can be seen walking on YouTube (butRead more
In the first version of the simple walker I used a custom atmega32 based board. I replaced it by a ‘custom’ version of the Arduino which I dubbed ‘ottantotto’ The microcontrollerboard is a breadboard version of the ‘ottantotto’ controller. It uses an ATmega88 instead of mega168 (mostly because they are cheaper, they sell forRead more
This is a try-out of a FabLab-ready kit design for a 2-Servo walking robot. The design is inspired by the lynxmotion kits and the designs by david buckley. The goal for this project is to make all mechanical parts for the servo walker out of 1 A4 size sheet of plywood (or perspex, lexan, delrin,Read more
The simple 2-servo walker (which I hope to use as a fablab-ready robot kit) went through its first paces today. The microcontrollerboard used is an ATmega32.. my ‘ottantotto’s haven’t arrived yet 🙁 The robot walks well, now it’s time to make it turn, avoid obstacles, sit up, make noise, etc… You can see it walkRead more

I’m really enthusiastic about the reprap project. The whole Idea of having a printer that can print functioning parts, just on your desktop is .. well.. cool. The reprap is a machine that can replicate part of its own parts. However, to build one from scratch you get a certain ‘bootstrap’ problem.. Hence you haveRead more
The previously discussed LED matrices have been mounted on a perspex stand, and instead of the mublock controller I have used a normal Arduino Diecimila. Since the software was originally written for WinAVR using some of the AVRlib functions, I haven’t made a full functioning Arduino sketch yet. Bitmap images give the start configuration forRead more
…or what to do with hundred-or-so tiny magnets… I took these magnets from a ball-and-magnetic-stick building kit, of which the balls had started to corrode. With a pair of pliers I crushed the plastic sticks, freeing the tiny magnets. They live happily on my refrigerator now.Read more
