Build your first Prima 1 experiment

Explore Xynova Prima 1, choose a manipulation task and turn it into a documented experiment. Start in your browser; prepare the verified hardware setup next.

What would you build with Prima 1?

Choose a task. Turn it into a test you can explain and repeat.

Action to test
Change the pen’s orientation relative to the palm, then hold a defined end pose.
What to record
Synchronized external video, measured joint state and available fingertip observations.
Define success first
Specify the initial pose, target orientation, tolerance and hold duration before testing.

A clip showing a pen held in the hand does not establish repeatable in-hand reorientation.

Human-operated; record operator input, feedback and interventions.

DEVELOPER PACKAGE · SOURCE CHECK 2026-10-03

Know what is documented. Confirm what you can run.

The public manual describes software support. A usable integration also needs the exact release, dependencies and setup instructions for your hand.

Public document

Product manual

English Product Manual V1.4 is listed in the official download center. Page 5 describes software and communication support.

What to check

Match this product document to the revision you received. It is not an installation guide.

Manufacturer-stated

SDK & operating system

The manual lists SDK support and ROS 1 / ROS 2 compatibility.

What to check

Obtain the release URL or package, version, license, supported OS / ROS distributions, installation steps and a read-only example.

Manufacturer-stated

Model & simulation

The manual lists URDF models, MuJoCo and Isaac Lab support.

What to check

Check the delivered model, mesh license, joint names, limits and simulator version. No runnable model was verified here.

Manufacturer-stated

Control interface

The manual lists CAN FD and EtherCAT. The product lists 22 total DOF.

What to check

Confirm the supplied transport and adapter, independently commanded axes, units, limits, feedback and stop procedure. Total DOF is not an action-vector length.

Manufacturer-stated

Fingertip observations

The product describes visuo-tactile fingertip sensing.

What to check

Confirm accessible channels, raw versus calibrated output, sample format, coordinate frames, calibration and timestamps.

Release to verify

Examples & reuse rights

The manual lists kinematics and reinforcement-learning examples. A public code release and its license have not been verified for this guide.

What to check

Ask for a versioned example, dependencies and permission to reuse code, meshes, recordings and data. “MIT control” is a control mode, not a software license.

Listing checked in the official download center. No public SDK release, runnable model or Prima 1 hardware trial was verified for this lesson.

FIRST TEST · OBSERVE BEFORE MOTION

Start with one signal you can explain.

After the manufacturer’s commissioning steps, use its documented observation-only example. Capture a named feedback channel and explain its units and clock before attempting a grasp.

  1. Identify the setup. Record hand side, hardware, firmware, software and transport. Follow the supplied mounting, power and stopping instructions.
  2. Read, then inspect. Save a short log from the documented example. Identify measured state versus command echo, timestamps and unavailable channels.
  3. Proceed only with a confirmed interface. Follow the manufacturer’s motion example and operating limits. Then use your task brief for a repeatable trial.
Your preparation checklist

Session-only notes. Checking a box records your confirmation; it does not test the hardware.

What have you confirmed?

0 of 5 preparation items checked.

Simulation additionally needs a revision-matched model, mesh license, joint limits and simulator version.

FROM A TEST TO USEFUL EVIDENCE

Make your result reproducible.

Record one row per initiated attempt, including interrupted trials. Choose one outcome: unassisted success, assisted success or failure. Define acceptance before testing and link the original recording.

Your practical task

  1. Choose a task and control mode in the planner, then download your brief.
  2. Fill in the starting conditions, attempt count and success rule.
  3. Use the checklist to identify missing SDK, model and sensor documentation.
  4. Save the lesson and create an experiment record when you have evidence to share.

What to produce: An editable Prima 1 experiment brief and a list of integration prerequisites.
