PowerBeam RoboFlagger™
A remote-controlled, dual-robot system for managing single-lane closures.
Use one flagger for single lane closure instead of 2.
Save money and headache.
Reduce risk to flaggers.
With live video and intelligent signal control, RoboFlaggerTM lets crews safely direct two-way
traffic from a distance — using only a mobile device.
RoboFlagger™ complies with all the requirements of CalTrans as stated in the MUTCD.
How It Works
RoboFlagger™ uses two autonomous robotic units placed at both ends of a closed lane zone:
- Open Lane Robot: Controls traffic on the lane that remains open.
- Closed Lane Robot: Controls access for vehicles that need to bypass the closure.
Each robot features:
- Four live cameras with 360° horizontal panning.
- Wireless remote control via mobile app (iOS & Android).
- Two display modes: STOP and SLOW, following the MUTCD standard.
Both signs must be on STOP before changing either one to SLOW. The app prevents setting both signs to SLOW at the same time.
Try It Out!
Use our interactive simulator to practice lane control logic and watch the simulated traffic react to the RoboFlagger™ in real time.
Instructions:
- Tap and hold a sign (STOP or SLOW) to change its state.
- You cannot switch to SLOW unless both robots are currently on STOP.
- To pan the camera, simply drag horizontally on the video preview.
- Status indicators show data like network speed, robot ID, and version.
