Welcome, F Series!
The F Series is a full body humanoid built by Realbotix for social interaction in education, elder care, entertainment, hospitality, and wellness settings. At 165 cm tall and 50 kg, it combines an internal frame with silicone skin, a realistic face, and a motorized wheeled base that reaches up to 3 km/h. Its 44 total degrees of freedom include 13 in the hands, while 17 electric servos in the face and neck drive expression, eye movement, and lip sync. It operates for up to four hours per charge and is designed for safe human interaction through low force servos. Conversational behavior can use ChatGPT, Gemini, Llama, and other AI models. Customizable skin tones, faces, and hair let the platform support distinctive characters and deployment concepts. With a Humanoid Guide Skill Score of 2, including navigation and manipulation ratings of 1 out of 5 each, it is an early stage platform centered on expressive communication rather than demanding physical work.
The documented operational capabilities are obstacle avoidance and sorting goods. Obstacle avoidance supports movement through indoor environments by recognizing and avoiding obstacles. Sorting goods gives the F Series a defined manipulation task for structured demonstrations and controlled workflows. Together, these capabilities suit applications that need basic navigation awareness alongside simple item handling. The navigation rating is 1 out of 5, and the manipulation rating is 1 out of 5, which positions both areas at an early stage. The wheeled base, 3 km/h maximum speed, and 13 degrees of freedom in the hands provide the physical configuration for these activities. Hospitality venues, education settings, wellness spaces, elder care contexts, and entertainment installations can build interactive experiences around obstacle aware movement and goods sorting.
In production, the F Series is made by US company Realbotix, which handcrafts robots in Las Vegas. Listed at 125,000 USD, it is offered with customizable skin tones, faces, and hair, and its magnetic face swapping system supports distinct character presentations. The platform accepts leading language models including ChatGPT, Gemini, and Llama, enabling operators to adapt conversations to different settings. Its significance lies in combining a lifelike expressive face, an accessible full body form, and limited physical task capability in one social robot platform. Rather than targeting heavy industrial automation, it provides a route for organizations to explore embodied AI interaction in public facing and care oriented environments. As an in production US platform, it contributes to the growing market for humanoid systems designed around engagement, identity, and repeatable customer or visitor experiences.
