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 – R2KT on it’s Way

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 […]

PROPTB6612FNG

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).

A Tin Can Robot – The Idea

Since R2D2 from StarWars is very popular with my kids these days,  I started working on a tin can robot which looks something like R2D2 and is remote controllable through a Android device (cell phone, tablet, ..). The body is made from a can which originally was for coffee. As you can see in the […]
