  • Rise of the LEGO® Digital Creator
    Rise of the LEGO® Digital Creator While you’ve always been able to build your own physical creations with a bucket of LEGO® bricks, the route to the same level of digital LEGO freedom for fans has taken a bit longer. The latest step in that effort sees the LEGO Group teaming up with Unity Technologies to create a system that doesn’t just allow anyone to make a LEGO video game, it teaches them the process. The Unity LEGO Microgame is the most recent microgame created by Unity with the purpose of getting people to design their own video game. But in this case, the interactive tutorial turns the act of creation into a sort of game in and of itself, allowing players to simply drag and drop LEGO bricks into a rendered scene and use them to populate their vision. Designers can even give their LEGO brick creations life with intelligent bricks that breath functionality into any model to which they’re attached. Users can even create LEGO models outside of the Unity platform using BrickLink Studio, and then simply drop them into their blossoming game. While this is just the beginning of this new Unity-powered toolset for LEGO fans, it’s destined to continue to grow. The biggest idea that could come to the Unity project is the potential ability for a fan to share their LEGO video game creations with one another and vote on which is the best, with an eye toward the LEGO Group officially adopting them and potentially releasing them with some of the profit going back to the creator.

Arkanoid), volanti (giochi di corse), pistole (es. Duck Hunt) potrebbero non essere controllabili con joystick, ma richiedono periferiche ad hoc, al momento non configurabili. - I giochi che richiedono controller analogici (Playstation, Nintendo 64, etc etc) potrebbero non essere controllabili con plance a levetta singola, ma richiedono, appunto, un joypad con analogici (venduto separatamente). - Questo elenco è relativo alla scheda NEW PLATINUM EDITION basata su Raspberry Pi4. - Gli emulatori di sistemi 3D (Playstation, Nintendo64, Dreamcast) e PC (Amiga, Commodore) sono presenti SOLO nella NEW PLATINUM Pi4 e non sulle versioni Pi3 Plus e Gold. - Gli emulatori Atomiswave, Sega Naomi (Virtua Tennis, Virtua Striker, etc.) sono presenti SOLO nelle schede Pi4. - La versione PLUS Pi3B+ emula solo 550 titoli ARCADE, generati casualmente al momento dell'acquisto e non modificabile.

  • Internet of Toys: Julia and Lego Mindstorms
    Internet of Toys: Julia and Lego Mindstorms Robin Deits December 13, 2015 Abstract The latest version of the Lego Mindstorms robotics system is an excel- lent candidate for the exploration of distributed robotics. I implemented bindings to the ev3dev operating system, which runs on the Mindstorms ev3 brick, in Julia. Using those bindings, I constructed a library to per- form a simple cooperative mapping task on a pair of mobile robots. Due to the hardware limitations of the ev3 processor, I was not yet able to run Julia onboard. Instead, I developed a simple server-client architec- ture using ZeroMQ [1] to allow Julia code to run off-board and control the Mindstorms robot over WiFi. With this system, I was able to map simple environments both in serial (with one robot) and in parallel (with a team of two robots).

  • Embedded Systems Software Engineer Is Responsible for Designing the Embedded Systems and Installing Them in Machines and Tools
    Embedded Systems Software Engineer Responsibilities Embedded systems software engineer is responsible for designing the embedded systems and installing them in machines and tools. They design and develop the software that controls the processor (micro-controllers and digital signal processors) of the machine. These systems provide functionality to the machines. The work of an embedded engineer is considered as important and challenging, since their efforts give utility to a machine. If you are keen on handling embedded systems software engineer responsibilities, then you need to be aware of the requirements, duties and career scope of this profile. Here are a few details for your assistance. An embedded system refers to a computerized system that controls the functioning of a specific machine. Every machine is built with a specific purpose. The embedded software functions like the brain of the machine and controls the tasks that the machine is designed to perform. The micro-controller is a chip that has the memory to store program data. It receives the commands, operates as per the inputted data and provides relevant results. Some popular examples of appliances that use embedded systems are digital watches, cars, robots, toys, electric appliances, etc. Understand the client requirements and write down the software details Study the specifications provided by the clients and seek clarifications for the doubts raised Submit the price quote and the details of the time required to execute the plan Receive the client's approval for the
