[CASPER] New video

We posted a new video showing our group performing with casper :

- Video tracking

- Dancing

- Mail fetching

- Vocal commands

 

[CASPER] can fetch and store mails

We made some improvements in our mail fetcher. Now, it’s able to fetch mails from most mail server ( pop3, secured or not). It can fetch the last mail received and store its content and subject into a file, so it can be read by our text-to-speach engine.

Moreover, we had the mail fetcher [...]

[CASPER] Fetching mails

We started to work on the first web service we would like to have casper use : MAILS.

We choose to use the C++ library Vmime which support many protocols such as pop or imap. It also has functions to parse the retrieved mails and get only the parts interesting to us.

We wrote [...]

[CASPER] Website is online !

Now you can visit our website ! For now, presentation of the project and videos are available as well as an awesome logo made by Thibault !

[CASPER] Http setup interface

Today, we have been looking for the simplest way of giving a http control interface to our project. We found that the C library Microhttpd was matching our needs.

It’s a library which will allow us to create a very simple http server on the BeagleBoard. This way a user will be able to [...]

[CASPER] New video about Mechanical advances

This week-end we added a new video showing how we are able to control Casper’s direction and bending remotely. Movements are smoother and have a good response time.

Now, that we got a UART connexion working on the BeagleBoard we will be soon trying to use it to control Casper.

[CASPER] Remote control on Casper

Today, we made some improvements in the way casper moves. Now, it will reach a specified target (direction + bending) passing by every intermediary position, preventing casper from brutal moves… Moreover, we added a way of specifying the movement’s speed.

Besides, now we can control Casper remotely. We are currently using a Zigbee module [...]

[CASPER] Prototype fonctionnel

Hier, nous avons finalisé le prototype mécanique.

Nous avons installé les trois servomoteurs sous le plan du socle. Nous les contrôlons grâce à un signal PWM de la carte de TP STM32.

Nous avons changé nos anciens câbles de carbone par des câbles en plastique. Il est apparu que bien que leurs propriétés mécaniques [...]

[CASPER] Avancées du projet côté mécanique…

Du côté de la mécanique, nous avons mis en pause le développement des drivers linux qui doivent à terme contrôler les moteurs. En effet, nous avons jugé que commander les moteurs au plus tôt et avec précision était plus prioritaire. Nous nous sommes donc penchés sur le contrôle des servos par PWM en utilisant [...]
