Description
- Can be controlled over Wi-Fi
- Less time you need to spend with compilers
- Most powerful and compact robot brain
- Suitable for beginner and advance users
The EZ-B V4 WiFi Robot Controller can be controlled over Wi-Fi using the graphical ez-builder software on your PC or mobile device, without needing to program. The less time you need to spend with compilers, hardware programmers, and debuggers, the more time you can spend building and designing robotic projects!
The EZ-B V4 WiFi Robot Controller is the world’s most powerful and compact robot brain, suitable for all skill levels – from beginner to advance. The stylish white plastic shell protects the speaker and electronics, with a speaker chamber for clear, enhanced audio. For advanced users, the ez-bv4 may be removed from its casing and mounted directly in your custom robot.
The EZ-B V4 WiFi Robot Controller Revolution introduces the world's easiest, most powerful and creative robots for R&D, experimentation and STEM education. Revolution is modular, so there is no limit to your creativity. These robots are assembled with ez-bits using clip’n’play technology for endless configurations.

J'utilise les EZ-B plus intensivement depuis un peu plus d'un an et ce sont des contrôleurs de robot (que ce soit celui-ci EZ-B v4 ou le Tiny) fantastiques. Combinés avec la plateforme de développement low-code ARC de Synthiam, cela vous ouvre un potentiel énorme pour rapidement mettre en oeuvre vos idées.
Le module est WiFi, donc pas besoin de télécharger le code comme avec un Arduino, votre PC communique directement avec le EZ-B. Possibilité de connexion directe des servomoteurs, haut parleur intégé ainsi qu'un connecteur pour brancher directement une caméra ainsi qu'une bonne quantité de ports numérique et analogique.
Pas obligatoire de conserver le boîtier en plastique. Dans mon cas je l'ai retiré...
Le meilleur contrôleur de tous les temps. Lorsqu'il est associé au logiciel de contrôle ARC de Synthiam, il est inégalé
RobotShop shipped this out in a timely manner and at a great price. Very pleased.
RobotShop l'a expédié en temps opportun et à un prix avantageux. Très content.
Fonctionne comme un rêve. Demandez-lui de contrôler la vitesse et la direction de mes robots ainsi que les retours vidéo à l'aide de la caméra EZ-B. Très heureux surtout avec l'interface et la distance.
