¿Existe otra combinación que mejore este proyecto?

Hola, mi nombre es Daniel , y soy profesor en la escuela pública en España, en niveles de secundaria y Bachillerato. En la última convocatoria, la Consejería de Educación , me concedió una subvención para un proyecto de Elaboración de materiales. Estoy trabajando actualmente en él. El proyecto trata de la construcción de Humanoides en 3D. Los humanoides pueden tener desde 8 a 16 servomotores digitales, en función del nivel del alumnado. Mi pregunta es, de entre todas las diferentes placas que ofrece PICAXE actualmente en el mercado, cuáles son las más adecuadas para este trabajo, teniendo en cuenta el nivel de carga que podrían tener que soportar. Por concretar la pregunta, por ejemplo con la Tecnología Picaxe, conectaba dos placas AXE 020 a un mismo dispositivo Bluetooth con procesadores 28 X2 en las placas. El bluetooth recibió la orden de un Smartphone. En este caso cada placa necesita una batería 6V 2400mAh de NIMH, para que los picos de funcionamiento del Bluetooth no dejaran a la placa sin energía, con lo que tenía que "tunear" algo las placas.

Necesito saber cuál es la Tecnología Picaxe más adecuada actualmente para un proyecto de estas características, para poder incorporarlo a este material, que pretende servir de apoyo en los próximos años al profesorado y alumnado que decida realizar este mismo proyecto en sus centros.

La idea es que pueda realizar todo con programas estilo blocky for picaxe, para la programación. Es decir sobre todo programación con bloques, ya que el proyecto es muy largo de hacer para un curso escolar, e incluso en cursos muy altos con alumnos muy avanzados es difícil acabarlo utilizando código directamente.

Muchas gracias por su atención.Un saludo.

Daniel

From Google translate:

"Hello, my name is Daniel, and I am a teacher in the public school in Spain, at the secondary and high school levels. In the last call, the Ministry of Education, awarded me a grant for a project of Preparation of materials. I am currently working on it. The project deals with the construction of Humanoids in 3D. Humanoids can have from 8 to 16 digital servo motors, depending on the level of the student body. My question is, of all the different boards currently offered by PICAXE on the market, which are the most suitable for this job, considering the level of load they might have to withstand. To specify the question, for example with Picaxe Technology, I connected two AX 020 boards to the same Bluetooth device with 28 X2 processors on the boards. The bluetooth received the order of a Smartphone. In this case, each board needs a 6V 2400mAh NIMH battery, so that the peaks of Bluetooth operation do not leave the board without power, which means that the boards had to be "tuned" somewhat.

I need to know which is the most appropriate Picaxe Technology currently for a project of these characteristics, in order to be able to incorporate it into this material, which intends to serve as support in the coming years for teachers and students who decide to carry out this same project in their centres.

The idea is that you can do everything with blocky for picaxe style programs, for programming. That is, above all, programming with blocks, since the project is very long to do for a school year, and even in very high courses with very advanced students it is difficult to finish it using code directly.

Thank you very much for your attention, regards.

Daniel"

Bonjour, je m'appelle Daniel, et je suis enseignant dans une école publique en Espagne, dans le secondaire (lycée). Le Ministère de l'Éducation m'a accordé une subvention pour un projet d'équipement en matériels sur lequel je travaille actuellement. Le projet porte sur la construction d'humanoïdes en 3D. Ils peuvent avoir de 8 à 16 servomoteurs numériques, selon le niveau des étudiants. Ma question est : parmi toutes les cartes actuellement proposées par PICAXE sur le marché, lesquelles sont les plus adaptées à ce travail, compte tenu du niveau de charge qu'elles pourraient avoir à supporter. Pour préciser, par exemple, j'ai connecté deux cartes AX020 pourvues de 28X2 au même appareil Bluetooth. Elles ont reçu via Bluetooth la commande d'un Smartphone. Chaque carte a besoin d'une batterie NIMH 6V 2400mAh, de sorte que les pics de consommation Bluetooth ne perturbent pas l'alimentation, ce qui signifie que les cartes ont dû être quelque peu "améliorées".

J'ai besoin de savoir quelle est la technologie Picaxe la plus appropriée actuellement pour un projet avec ces caractéristiques, afin de pouvoir l'intégrer dans ce matériel, qui servira de support dans les années à venir pour les enseignants et les étudiants qui décident de le réaliser dans leur établissement.

L'idée est que vous pouvez tout faire avec Blockly, pour la programmation. Sans la programmation avec des blocs, puisque le projet est très long à faire pour une année scolaire, et même dans des cours de niveaux supérieurs avec des élèves très avancés, il est difficile de le terminer en utilisant du code directement.

Merci beaucoup pour votre attention, cordialement.

Hi,
Los humanoides pueden tener desde 8 a 16 servomotores digitales, en función del nivel del alumnado.
Because there have been no Answers yet, I will make a start. But personally, I don't have any experience of using a large number of servos (nor Blockly), but This Finished Project shows what can be done with a single 20X2. See the demonstration YouTube Video in post #22.

However, for a "High Quality" application for up to 16 Digital Servos, I would look at the AXE 031 with its Data Sheet HERE. It is not specifically (i.e. only) intended for PICAXE, so you will need to make a special connection for the Programming / Download Socket, perhaps using the AXE029 Breadboard Adapter and a Right-Angle Header (cut to 4 pins). The AXE031 is "Pre-Assembled" (not a Kit like AXE029 and many PICaxe boards) and does include a 18M2 PICaxe.

Cheers, Alan.

Thank you Alan for everything. I have been seeing the links that you have put me in your comment. Congratulations on your work with the Humanoid legs. They move wonderfully.
I've been looking at the AXE 031 board as well, and it seems like a great solution for what I've been looking for. So I only see the problem of not being able to use it only with Blockly, or do you think it is possible to use it? My students are from Secondary school and high school, and there is no material time in class to program with code using Basic.
Cheers, Daniel

Hi,

The Humanoid Legs are not my work, I was just trying to demonstrate that there are sections of the forum which show "completed projects" that other people have done with PICaxe.
So I only see the problem of not being able to use it only with Blockly, or do you think it is possible to use it? My students are from Secondary school and high school, and there is no material time in class to program with code using Basic.
Sorry, I don't know. Blockly certainly supports the I2C Bus commands, but I would expect to be able to use "Symbols" inside the "Blue Blocks", not just numbers (0 to 255). Also the "AXE031 Slave Address" is not shown (see the pull-down menu in my Screenshot), the Address Byte can be entered manually (%11000010) but I would hope to edit something (an .XML file ? ) so that the Address and some Symbols (e.g. "SERVO1RegisterH" , etc.) are directly available to the Students. Note that B.1 and B.4 are the I2C SDA and SCL pins, so could not be used directly as Servo Output pins. The "Blockly User Manual" doesn't say much about the "Advanced - I2C" commands.

This is very much an "Educational" application so maybe Rev. Ed. / @Technical can help?

Cheers, Alan.

Thanks for your suggestions Alan. I will analyze what you have sent me in the attached file. It will take a while to review it, but I will do it because I am very interested. I also just wrote to the technical service that you have told me about.
Thank you very much again, and I will comment on my progress in this work. I hope it's soon :)
