I updated my installer-script for the Parallax Propeller tool-chain (GCC, SPIN, BST and others) to make it work (agin) on Ubuntu 14.04. Main issue was that the current „makeinfo“ seems not to be happy with some of the „.texi“ files from „binutils“ used by the Propeller GCC. Thus, I added a patch to the script […]
I put together a project roundup for the tin can R2D2: TinCan R2D2 roundup
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 […]
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 […]
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).
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“ […]
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 […]
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 […]
I uploaded (and also on OBEX) a little SPIN script to use the Thosiba TB6612FNG dual motor controller on the Parallax Propeller. The driver offers methods to operate each motor individually or both motors together (by sending the same command to each, or sending a different command to each).
