Senses your step.
Adjusts mid-motion.
Shares the aisle.
Closer builds floor robots that read the people around them and adjust their path in real time, so retail and logistics teams add robotic coverage in live aisles without fencing off the floor.
The real bottleneck
The cage is the problem,
not the solution.
Fenced robot zones were designed for fixed industrial arms, not mobile service robots that need to move through live aisles. Every cage you install freezes a portion of your floor and separates your workforce from the robot. Closer is built from the ground up around proximity awareness: the robot reads its human neighbors continuously and adjusts in real time, no exclusion zone required.
Sensing pipeline
Three sensing layers. One smooth response.
The robot doesn't stop and wait. It reads the space around it at multiple depths and adjusts trajectory continuously, so the aisle stays in motion.
Ultrasonic proximity ring
Eight ultrasonic sensors form a 360-degree proximity ring detecting moving bodies at 0.15m to 3m range. Updates at 50Hz. First line of spatial awareness.
Depth camera zone
A forward-facing depth camera builds a real-time occupancy grid of the aisle ahead, identifying foot and leg positions at 30fps. Resolves precise approach vectors.
Floor-contact force feedback
Pressure sensors in the wheel base detect unexpected contact forces from foot contact or wheel-brush, triggering an immediate deceleration within 40ms.
Motion adjustment output
A lightweight onboard planner fuses all three inputs and issues smooth velocity and heading corrections every 20ms, keeping the robot on task while yielding appropriately.
Pilot evidence
What beta operators are saying
response time
in pilot trials
We had written off two aisles in our Kobe facility as robot-incompatible because of foot traffic density. After three weeks with Closer, both aisles are running continuous robot coverage. The response to our pickers is noticeably smooth, not abrupt.
The floor team stopped noticing the robot by week two. That is exactly what we needed before we could talk to our safety officer about wider deployment. No special training, no revised SOPs for how to walk near it.
