Obstacle or Safety-Field Stops
A J1600 that stops during an autonomous task is usually doing its job. The vehicle carries a 360-degree protective field, monitored by two 2D safety LiDAR scanners and an independent safety controller, and it stops when a person or object enters that field. This page explains the behavior and how to get moving again.
How the safety field behaves
- The protective field surrounds the vehicle and supports both forward and reverse autonomous travel.
- The field is speed-dependent: it expands as travel speed increases.
- Blue light strips project the current protected area onto the floor. White lights indicate manual mode.
- Person detection and braking are certified safety functions within the layered safety architecture. For the design, see How J1600 safety works.
Resuming after a stop
- Clear the safety field — step out of the protected area and remove any obstruction.
- Press the LED start/resume button to continue the task.
The robot also avoids obstacles on its own: where a path exists, it routes around objects and people rather than stopping. A full stop typically means the field itself was breached or no clear route remained.
Frequent stops on a route
If a route triggers constant stops:
- Reduce congestion on the route, or define preferred travel zones so the robot favors calmer paths through production areas.
- For genuinely crowded areas — an overflowing receiving zone at truck arrival, for example — take over with the tiller and drive the congested portion manually. Immediate manual takeover is a core part of dual mode.
Other stop controls
Stops can also come from deliberate controls rather than the safety field:
- three emergency-stop buttons;
- the belly button on the tiller, which stops the vehicle and reverses it away from the operator;
- grabbing or moving the tiller, which returns the robot to manual control;
- tiller-position switches, which act as emergency-stop and manual-control inputs.
Check whether one of these was activated before assuming a fault.
When it is not safety behavior
If the robot stops with a clear field, no engaged stop control, and a valid route, contact support — see Submit a support request.
