Bridging Automation and Storage with Open Computers Refined Storage Driver
When you run a Minecraft modpack built around programmable machines and a centralized digital warehouse, the missing link is often direct communication between the two systems. Open Computers gives you Lua-driven computers and robots, while Refined Storage handles bulk item storage and automated crafting. The bridge that connects them is the Open Computers Refined Storage Driver, commonly shortened to ocrsdriver. This small add-on unlocks a dedicated component that lets your in-game programs query, move, and craft items through the Refined Storage network without any manual intervention.
Why the Driver Is Required
Out of the box, Open Computers cannot talk to Refined Storage. Attaching an adapter to a storage block does nothing useful for inventory access or crafting requests. The driver changes that by adding the block_refinedstorage_interface component. Once installed, your Lua scripts can list every stored item, extract resources, trigger crafting jobs, and even read the network's power draw. Keep in mind that Refined Storage only introduced native support for this kind of integration in versions for Minecraft 1.11.2 and newer. For older setups, particularly Minecraft 1.10.2, this driver is the only practical way to get the two mods working together.
Installing the Driver
Before you download Bridging Automation and Storage with Open Computers Refined Storage Driver, confirm that your modpack runs on Minecraft 1.10.2 with the Forge loader. The driver is not designed for newer game versions, so using it on later releases is unnecessary. To install, drop the jar file into the mods folder of your instance, restart the game, and verify that both Open Computers and Refined Storage are present. The component will appear automatically in your computer's component list. If you prefer a more streamlined approach, some launchers offer curated mod lists that include this driver, letting you build a stable 1.10.2 pack with minimal effort.
Core Commands for Your Scripts
Once the component is active, you get a practical set of methods. These cover most automation scenarios you will need for a self-managing warehouse:
isConnected()— checks whether the node is linked to the RS network.getEnergyUsage()— returns the current energy consumption of the whole network per tick.getItems()— fetches a table of all items stored in the system.getItem(itemstack, cmpMeta, cmpNbt, cmpOre)— finds a specific stack with optional metadata, NBT, and ore dictionary matching.extractItem(itemstack, amount, side)— moves the requested amount to a given side and returns the actual count moved.getFluids()— lists all fluid stacks in the network.getFluid(fluidstack)— searches for a fluid by sample.extractFluid(fluidstack, amount, side)— extracts fluids in millibuckets.getTasks()— shows the current crafting queue.getPatterns()— lists all known crafting patterns.hasPattern(itemstack)— checks if a pattern exists for the given item.getMissingItems(itemstack, amount)— calculates the missing ingredients for crafting a specified quantity.craftItem(itemstack, amount)— sends a crafting request for the desired amount.cancelCrafting(itemstack)— cancels all crafting jobs for that item and returns the number of canceled tasks.
Practical Automation Examples
Automatic Overflow Disposal
Suppose your storage holds more than 8192 units of a common resource. A simple loop can call extractItem repeatedly, dumping excess items into a trash can placed below the interface. Use the sides library to specify the correct output direction. This keeps your network tidy without manual sorting.
Self-Replenishing Consumables
A more advanced script can maintain a steady stock of torches or levers. Every five seconds, the program checks whether a pattern exists, calculates the difference between a target amount (say, 64) and the current inventory, then triggers craftItem for the shortfall. If no pattern is available, it logs a warning to the console. This turns your RS network into a self-sufficient depot that never runs dry.
Known Limitations
The driver places no speed limits on item or fluid extraction. With just a cable and an adapter, a script can move resources at extreme rates, which may unbalance multiplayer servers or accidentally drain your entire stock. Add your own delays and validation checks when writing scripts. Also, remember that this mod targets Minecraft 1.10.2 exclusively. For later game versions, the built-in integration in Refined Storage makes the driver redundant.
Final Thoughts
For anyone running a Minecraft 1.10.2 pack, the Open Computers Refined Storage Driver is a compact but essential piece of the automation puzzle. It removes the barrier between programmable logic and digital storage, enabling smart factories, dynamic sorting, and adaptive crafting chains. The API is straightforward enough for Lua beginners, yet flexible enough for seasoned engineers. If your modpack still lives in the 1.10.2 era, this driver deserves a permanent spot in your mods folder. To get started, simply download Bridging Automation and Storage with Open Computers Refined Storage Driver and follow the install steps above. Knowing how to install it correctly ensures a stable base for your most ambitious automation projects.
