The DIO (Digital IO) brick for my brick-o-lage project is already finished. I designed schematic and PCB using fritzing . Also I ordered the PCBs from fritzing FAB (and they turned out great). For the firmware I used my own libemb as a basis. DIO Brick Specifications Uses a MSP430G2553 from TI Runs custom firmware […]

Bric(k)-o-lage – smart bricks the “bricolage” way

A while ago, I started a new project trying to create different “smart” bricks which will interconnect with some other well known brick systems (e.g. Lego). By “smart” bricks, bricks are meant which are able to perform a certain functionality like driving LEDs, detecting button presses, control DC motors or servos, read sensors and so […]

A Tin Can Robot – Roundup

I put together a project roundup for the tin can R2D2: TinCan R2D2 roundup

A Tin Can Robot – Basic Schematic

Documentation day today :-). I got also around drawing a basic schematic (using Fritzing) for the tin can robots electronics. Some notes on the schematic: I don’t use the Propeller “directly” but use the Propeller QuickStart board. The schematic below is soldered on perf-board and then attached as a shield to the QuickStart. Fritzing offered […]

A Tin Can Robot – Android App to Control

Finally I got around hacking a basic Android App to control my tin can robots. To quickly get a result, I used Processings Android mode and the Ketai library for the Bluetooth stuff. Regarding the effort needed for the results, they turned out pretty well. The App has the following features so far: Device Discovery […]

A Tin Can Robot – Short Video

Ok, the hardware for both robots (black R2D2 and pink R2KT) is done. Also a first version of the software is loaded on the Parallax Propeller inside the two bots. In the video below you could see them driving (remote controlled from smartphone/tablet).

A Tin Can Robot – Driving

The tin can based R2D2 robot driving around, remote controlled through tablet using Bluetooth: The sound in the video is pretty poor. But what you here so far is a typical R2D2 beep-beep on start-up (or when you request it by remote command), an other beep when a new command was received, some sad “ohhhh” […]

A Tin Can Robot – Change of Plans

I decided to slightly change plans for the tin can robot. Since I bought a 3D printer lately, it now totally makes sense to print out all the additional parts around the can (instead of poorly handcraft them from whatever). Thus, I started designing all stuff I like to print within OpenSCAD. Below you could […]

A Tin Can Robot – Electronics

I roughly put together most of the electronic parts needed to make the robot drive. The video shows operation of the two motors through my cellphone using Bluetooth. Also I added basic playback of PCM audio files through a speaker I connected to the Propeller. The audio is a must to play back the typical […]
