Pulsar F1 wants to stroke like a human hand, not a piston, but Kickstarter suspended its campaign

A new penis stroker device with movements based on human hand motion video is in development, and can be connected to custom interactive content and AI companions for live interactions.

The Pulsar F1 is being marketed as offering an alternative to the modern classic penis stroker design, and not just because it looks more like a vase than a large SLR camera lens. Hongkong Pulsar Technology Ltd, the Hong Kong-based company behind the device, said that its movement was trained on over 50 hours of “human technique” video recorded by the firm’s team.

They created an enormous video cache showing people making over 40 different masturbation movements with their hands. Everything from what the company called a ‘pitch throw’ motion (an arcing stroke that ends in a release), ‘willow pull’ (encircling fingers with short upward pulls) and ‘cat paw’ (balling fists and moving them around), to what the Brits would call a good old classic wanking movement.

Motion data from the videos was transferred to what the company calls Motion Signatures, which give stroking and vibration movements in the penis sleeve of the device. The idea is that because the data comes from video capture of real human movement, it results in a more natural feel, with the little inconsistencies in rhythm and flow that you’d expect from a human interaction.

The company said that the motion capture plan was inspired by a Japan-based massage and rehab team it spoke with.

Hongkong Pulsar Technology said that an exchange with this massage team “led us to study how human movement changes in rhythm, pace, and progression. That question became the starting point for Pulsar’s Motion Intelligence.”

It added: “The aim was to move beyond a short list of repeating presets, toward movement that can respond to the moment.”

The device’s AI motion engine can, according to the company, “arrange, blend and adapt” the Motion Signatures through a masturbation session. You’ll also have the option to save preferences to your account so the AI can learn which movements and sensations you like most and integrate more of them into sessions.

The company said: “No two people respond the same way. AI voice commands and conversation can adapt the rhythm as an interaction unfolds. Pulsar also learns from the preferences you choose to share, so future sessions can feel more personal over time.”

Rather than using an app for syncing, like many penis stroker companies do, Pulsar’s device is connected to content and other devices through a web browser. The Pulsar F1 can be used in isolation or synced with local or online video, including VR, with support for Funscripts (digital scripts that trigger sextech device movements closely synced with video content).

However, the forthcoming device is primarily being pitched alongside its compatibility with AI companion characters. Pulsar F1 owners will be able to create AI avatar companions online, selecting their voice, appearance and personality, and connect to them for masturbation sync sessions.

Pulsar said that basic access to AI companion creation and syncing would not require a subscription.

The Pulsar F1 is 250 millimeters tall, with a width of 102 millimeters at its widest section. It weighs 556 grams, can be used for up to an hour between charges, and is water resistant (rated IPX6).

The company said the device is going through hardware testing and fine-tuning ahead of mass production. It’s being sold for the pre-order price of $99 (a $139 bundle with a lubricant warmer is also available), with the eventual sale price set to rise to $199.

It did initially launch on Kickstarter, but the device’s campaign on the crowdfunding site was suspended.

Hongkong Pulsar Technology said: “According to the notice we received, the decision concerned its restriction on AI companions offering romantic or sexual companionship, and a concern about the product being available for sale outside Kickstarter. During the campaign, our website introduced Pulsar F1 and directed visitors to Kickstarter; it did not accept product orders.”

Earlier in 2026 Kickstarter introduced stricter rules for adult content on its platform, but then quickly reversed the move following pushback from creators making a living from content that would be affected.
