Yaskawa Motoman robots are programmed with the INFORM language on a teach pendant, and with MotoSim for offline simulation. Before you wrestle with vendor-specific syntax, master the universal fundamentals — frames, the tool centre point, joint vs linear motion, I/O, pick-and-place, payload, and safety — hands-on in a free browser simulator. These concepts carry straight onto a Yaskawa teach pendant.
Honest note: this is not a Yaskawa emulator and it does not run Yaskawa INFORM. It teaches the transferable robot-programming fundamentals using real URScript on a UR-style arm.
The Yaskawa stack
How Yaskawa Motoman robots are actually programmed
Yaskawa is one of the world’s largest industrial-robot manufacturers, and its Motoman programming workflow is built around a few core tools. Knowing what each one does — and what it expects you to already understand — tells you exactly where to start.
A six-axis articulated arm — the same articulated kinematics as a Yaskawa Motoman robot. You program these joints with INFORM (MOVJ / MOVL) on a real arm, and with universal fundamentals in our browser simulator.
The teach pendant & INFORM language
Most Yaskawa programming happens on the teach pendant connected to the robot controller. You jog the arm, record positions, and build a job — Yaskawa’s name for a robot program. Jobs are written in INFORM, Yaskawa’s robot language: a list of motion moves (MOVJ for joint, MOVL for linear), I/O instructions, variables, and flow logic. This is the bread-and-butter of day-to-day Motoman work.
Controllers: YRC1000, DX & FS series
Yaskawa robots run on a controller that executes the INFORM jobs. The YRC1000 is Yaskawa’s modern controller, succeeding earlier generations like the DX and FS series. The controller handles motion, safety, and I/O, and it is what your teach pendant talks to — but the programming concepts you use are the same across generations.
MotoSim EG-VRC for offline programming
MotoSim EG-VRC is Yaskawa’s official PC-based offline-programming and simulation suite. It builds a 3D model of your robot and cell so you can write, test, and optimize INFORM jobs — checking reach, cycle time, and collisions — before touching the real machine. It is Yaskawa-specific and licensed: the standard tool for serious Motoman cell design.
HC-series collaborative robots
Yaskawa’s HC series are collaborative robots (cobots) designed to work safely near people. They can be programmed with simplified, hand-guidance-friendly workflows in addition to traditional INFORM methods — but the same fundamentals of frames, motion, payload, and force-limited safety still apply.
What transfers
The fundamentals that carry onto a Yaskawa arm
Yaskawa’s INFORM language and MotoSim are vendor-specific, but the concepts beneath them are not. Every six-axis articulated robot — Yaskawa, FANUC, ABB, Universal Robots — is driven by the same handful of ideas. Our browser simulator teaches each one hands-on using real URScript, so you build the mental model first and learn Yaskawa’s syntax second.
Every major brand maps to the same ideas. Yaskawa Motoman uses INFORM; UR uses URScript — the motion, I/O and frame concepts are shared.World, base, user and tool frames decide where the robot thinks it is. Yaskawa calls these user frames and tool data; the idea is identical everywhere.
Frames & coordinate systems
World, base, user, and tool frames decide where the robot thinks it is. Yaskawa uses user frames and tool data; the idea is identical everywhere.
Tool Center Point (TCP)
Define the working point of your gripper or tool so the robot moves the right spot to the right place. Get the TCP wrong and every position is off.
Joint vs linear motion
Joint moves (Yaskawa MOVJ / URScript movej) are fast through joint space; linear moves (Yaskawa MOVL / movel) keep the tool on a straight Cartesian line. Knowing when to use each is core to every brand.
Waypoints & sequencing
Approach, act, retract: chaining points into a smooth, safe path is the same skill on any controller.
Digital I/O & grippers
Reading inputs and setting outputs to drive a gripper or signal a PLC is universal — only the instruction names change.
Payload, reach & collision safety
Configure payload, respect reach limits, and avoid collisions and over-force contact. On cobots like Yaskawa’s HC series this becomes force-limited collaborative safety.
Concept mapping
What you learn here vs what it’s called on Yaskawa
You program in real URScript in the simulator. Here is how each concept maps to the Yaskawa Motoman world so you can see the bridge clearly. The interface differs; the thinking is the same.
MOVJ vs MOVL on a Yaskawa robot is exactly movej vs movel here: a joint move takes the fastest path through joint space, while a linear move keeps the tool on a straight Cartesian line.
Learned here (URScript / UR-style)
On a Yaskawa Motoman robot
movej — joint move
MOVJ instruction in INFORM
movel — linear move
MOVL instruction in INFORM
Tool center point (set_tcp)
Tool data / tool file setup
Base / feature frames
User frame setup
Digital I/O (set_digital_out)
DOUT / I/O instructions in INFORM

Note: this mapping shows conceptual equivalence to help you transfer skills. The simulator does not generate or run Yaskawa INFORM code — for that, you would use Yaskawa’s MotoSim EG-VRC or a real teach pendant.
Where to start
Yaskawa-specific tools vs learning the fundamentals first
You can jump straight into Yaskawa’s ecosystem — but if you have never programmed a robot, the tools assume knowledge you do not have yet, and the licences and setup get in the way of practising. The faster path is to build the fundamentals where they are free and frictionless, then layer Yaskawa’s syntax on top.
Jumping straight to Yaskawa tools
MotoSim EG-VRC is licensed Windows software; a real teach pendant means real (or rented) hardware. Both are powerful, but they assume you already understand frames, TCP, and motion types — so beginners spend their energy fighting the interface instead of learning to think like a robot programmer.
Fundamentals first, in the browser
Open a tab, write real URScript on a UR-style arm, and practise the exact concepts Yaskawa relies on — for free, with graded tasks. When you reach a Motoman pendant, you are learning new syntax, not a new way of thinking.
Offline programming workflow: build the cell, write and simulate the job on a PC, then deploy to the controller. Yaskawa’s tool for this is MotoSim EG-VRC; the underlying loop is the same skill you build in the browser.
A practical roadmap to Yaskawa programming
1Build the fundamentals here: frames, TCP, joint vs linear motion, waypoints, I/O, payload, and collision/safety — graded, in the browser.
2Program a full pick-and-place cycle in URScript so the end-to-end workflow (approach, grasp, traverse, place, release) is second nature.
3Read up on Yaskawa INFORM: how MOVJ/MOVL moves, variables, and I/O instructions are entered into a job on the teach pendant.
4Install Yaskawa MotoSim EG-VRC (or use a real teach pendant) and re-create a simple pick-and-place — now you are only learning Yaskawa’s interface and syntax.
5Add Yaskawa-specific safety and HC-series collaborative force limits once the basics are fluent.
Cobots & safety
Yaskawa HC cobots and collaborative safety
Yaskawa’s HC series are collaborative robots built to operate near people without the traditional safety cage. They support easier setup methods — including hand-guidance — alongside conventional INFORM programming. That lower barrier makes cobots a common entry point into robot programming.
But collaborative does not mean consequence-free. Whatever the brand, cobot safety comes down to force and speed limits, protective stops on unexpected contact, payload that is configured correctly, and a program that avoids collisions in the first place. Our simulator teaches exactly that: tasks are graded not just on placing the part, but on staying within a force limit and avoiding over-force contact — the same discipline a Yaskawa HC cobot (or any cobot) demands.
Collaborative safety in one picture: force and speed limits, a protected zone, and a protective stop on unexpected contact — the discipline behind Yaskawa’s HC-series (HC10, HC20) cobots.
In the simulator
From first jog to a graded pick-and-place cell
You do not just watch — you write real URScript, run it on a simulated six-axis arm under physics, and get graded against a real goal. Every skill here is a fundamental Yaskawa programmers rely on too.
The pick-and-place cycle: approach, grasp, lift, traverse, place, release — the backbone of most Motoman jobs.Digital I/O drives the gripper and handshakes with a PLC. Yaskawa does this with DOUT / I/O instructions in INFORM.Payload and TCP change reach, accuracy and safe speed — set as tool load and tool data on a Yaskawa controller.
Jogging & frames
Move the arm in joint and Cartesian space; understand base vs tool frames and how the TCP is defined.
Joint vs linear moves
movej vs movel — when each is right, and how speed and acceleration change the motion (the Yaskawa MOVJ/MOVL distinction).
Digital I/O & gripper
Read and set digital signals; open and close a gripper to actually pick something up.
Pick-and-place A→B
Approach, grasp, lift, traverse, place, release — the backbone of real robot and cobot work.
Payload & TCP
Configure payload and tool center point and see how they change reach, accuracy, and safe speed.
Collision & force-limited safety
Trigger and avoid protective stops and over-force contact — the heart of collaborative safety.
Free play → graded course → certificate: the path from your first jog to a portfolio-ready pick-and-place, ready to take onto a Yaskawa pendant.
Questions
Yaskawa robot programming FAQ
On real hardware, a Yaskawa Motoman robot is programmed mainly from the teach pendant attached to its controller (the YRC1000, or older DX and FS series). You jog the arm to positions, record them as steps, and build a job out of move instructions (MOVJ for joint moves, MOVL for linear moves), I/O instructions, variables, and logic — all written in Yaskawa’s INFORM robot language. For offline work, Yaskawa offers MotoSim EG-VRC, a PC-based 3D simulation and offline-programming tool. Before any of that pays off, though, you need the underlying concepts — frames, the tool center point, joint vs linear motion, I/O, and safety — which is exactly what you can practice here in the browser.
Yaskawa Motoman robots are programmed in INFORM, Yaskawa’s robot programming language. INFORM jobs are built on the teach pendant as a list of instructions — MOVJ and MOVL motion moves, I/O instructions, variables, and flow control. MotoSim EG-VRC is Yaskawa’s PC software for writing and simulating INFORM jobs offline. Our simulator does not run INFORM; it teaches the same fundamentals (motion types, frames, TCP, I/O, safety) using real URScript so the concepts transfer when you move to a Motoman pendant.
INFORM is Yaskawa Motoman’s robot programming language — the instruction set you use to write robot jobs on the teach pendant. An INFORM job is a sequence of instructions: motion moves (MOVJ for joint, MOVL for linear), speed and positioning settings, digital I/O, variables, and flow logic such as jumps and calls. It runs on Yaskawa controllers like the YRC1000. Our browser simulator does not generate or run INFORM, but it teaches the underlying concepts — motion types, frames, TCP, I/O, and safety — so INFORM becomes a matter of learning Yaskawa’s syntax rather than learning to think like a robot programmer from scratch.
MotoSim EG-VRC is Yaskawa’s official offline-programming and simulation software. It runs on a Windows PC, builds a 3D model of your Motoman robot and work cell, and lets you write and test INFORM jobs, check reach and cycle time, and detect collisions without the physical robot. It is the standard tool integrators use to validate Yaskawa programs before deployment. It is Yaskawa-specific and licensed. Our browser simulator is a different thing: a free, install-free way to learn the robot-programming fundamentals that make tools like MotoSim much easier to pick up.
You can learn the fundamentals of robot programming online for free, and that is most of the battle. Yaskawa’s INFORM language and MotoSim are Yaskawa-specific, but the concepts beneath them — frames, the TCP, joint vs linear moves, waypoints, digital I/O and grippers, payload, and collision/safety — are universal. Our simulator teaches those hands-on in the browser, free to start, using real URScript on a UR-style arm. Master them and a Yaskawa teach pendant becomes a matter of learning INFORM’s specific syntax, not learning to think like a robot programmer from scratch.
No — to be straight with you, this is not a Yaskawa or Motoman emulator and it does not run Yaskawa INFORM code or MotoSim. It is a browser-based robot-programming trainer that teaches the universal fundamentals of programming a six-axis arm using real URScript. Everything you learn here — frames, TCP, motion types, I/O, pick-and-place, payload, and safety — transfers to Yaskawa Motoman. For Yaskawa-specific syntax and offline simulation you would use Yaskawa’s MotoSim EG-VRC; this is how you build the foundation first.
