01 / ROBOTICS
Give motion
a clear interface.
Understand commands, coordinate frames, state feedback, and the boundaries between a browser and a robot controller.
THE DEVELOPER’S MOTION PLAYGROUND
CODE IT.
MOVE IT.
Robot arms. AI agents. Virtual claws.
Explore the APIs behind the next move—with practical guides and a hands-on browser playground.
Start in simulation. Understand every command.

01 / Find your direction
ONE IDEA.
ENDLESS NEXT MOVES.
From physical-arm architecture to virtual-game interactions. Choose the world you’re building for.
Give motion
02 / INTELLIGENCE
Plan with AI.
Keep clear limits.
Connect perception, planning, and bounded agent tools. Separate a proposed action from permission to execute it.
03 / GAME SYSTEMS
Build the claw.
Shape the moment.
Design virtual aiming, drops, and repeatable game state. Explore a practice cabinet with no purchases or real prizes.
02 / A small API. A clear starting point.
LESS GUESSWORK.
MORE UNDERSTANDING.
Try an actual, local JavaScript state API—not a pretend cloud endpoint. Choose a pose, change the illustrated gripper, and inspect the resulting state.
Readable by design
Three named poses and a small documented interface.

03 / Build in the right order
INTENT IS JUST
THE BEGINNING.
Our guides use a simple design discipline: describe, check, observe, and recover. A drawing is not a physical safety system.
01
Describe the move
Name the goal, units, coordinate frame, and limits before you ask for motion.
02
Check the boundaries
Validate the proposed operation and keep permissions separate from planning.
03
Observe the result
Distinguish an accepted request from a measured outcome or a local visual change.
04
Recover deliberately
Design timeouts, cancellations, and resets before adding a more complicated workflow.
Keep exploring
NOTES FOR THE NEXT BUILD.
Robot Arm API: A Practical Beginner’s Guide
Start with the contract, not the motor. A practical guide to commands, feedback, capabilities, and a simulation-first workflow.
Agentic Arm APIs: Bounded Tools, Approvals, and Recovery
Give an agent useful skills without unrestricted actuator access. Design narrow tools, reviewable plans, and honest outcomes.
Gacha Game Arm API: Build a Clear Virtual Claw Loop
Model aim, descend, close, and return as explicit states. Keep virtual mechanics understandable and independent of frame rate.

About ArmAPI.comWhat is ArmAPI.com?
A developer resource for robot arm API design, remote-control architecture, AI workflows, and virtual claw games. The site includes guides, a local JavaScript state library, and two browser demonstrations.
Can this website control a real robot arm?
No. Its controls update an illustration in your browser. Physical motion requires a separate controller integration, verified hardware behavior, and application-specific safeguarding. Start with the safety and scope notes.
Is there a hosted API or API key?
No hosted robot service is provided here. The documented API is a local JavaScript library included with this website. It does not make network requests.
What does “gacha game arm API” mean here?
On ArmAPI.com, the phrase describes a virtual claw’s control and state interface. The practice cabinet has deterministic hit regions, no money, and no real rewards. It is separate from physical robot control.
Where should I begin?
Try the playground, read the robot arm API beginner’s guide, then use the documentation to inspect the same local state model.
A little code. A lot to explore.
