DFRobot Launches seeMote Cap, Its Latest Vision Pro Accessory

DFRobot’s launch demonstration puts that idea into a training simulation, with Cap mounted on an orthopedic drill so its position and angle can be represented inside visionOS.

How it tracks a tool

Cap tracks six degrees of freedom, or 6DoF. That means an app can follow both where the object moves and how it turns. Cap requires visionOS 27 and uses Apple’s Spatial Accessory API to share tracking data with compatible apps.

The 35-gram module measures 45 × 45 × 32 millimeters. It connects over Bluetooth, has two programmable buttons, and recharges through USB-C. A threaded mount underneath accepts a compatible screw or adapter; the setup guide also describes using a strap to secure it to an existing tool.

Mounting affects tracking. DFRobot specifies 270-degree coverage, with a blind spot underneath. Its instructions say the infrared tracking points must stay visible to Vision Pro as the tool moves, without being blocked by a hand, the tool, or its mount.

Built for developers

This is hardware for building a compatible experience. Attaching Cap to an object does not automatically add tool support to every Vision Pro app.

DFRobot provides developer resources (opens in a new tab), including tracking configuration files, 3D models, and the source code for its seeMoteViewer Cap sample app. The setup guide walks developers through opening the project in Xcode on a Mac and running it on Vision Pro with Developer Mode enabled.

Price and shipping

Preorders opened September 14. The $229 package includes one seeMote Cap, a USB-C cable, and a quick-start guide.

DFRobot’s store currently estimates late September shipping for non-U.S. orders and early November from its U.S. warehouse. U.S. buyers can request late September dispatch from China, but the company says import charges would be payable by the recipient.

Developers can already explore the sample project and mounting instructions to plan an app around the tool they want to track.
