SEER Robotics Forklift manual control device (SFL-Handle-ZY)

Every autonomous forklift eventually meets a moment its navigation software did not plan for: a pallet left askew at the end of an aisle, a vehicle halted beside a racking upright, a commissioning engineer who needs to ease the forks into position by a few centimetres. At that moment the most valuable component on the truck is not the scanner or the route planner but the cable in an operator's hand. The SEER Robotics Forklift manual control device (SFL-Handle-ZY) sits at the far end of that cable: a compact handheld that carries travel, steering and mast commands over a hard-wired I/O link, guarded by a dual-channel emergency stop and a 3-position safety enable switch.

Robots Europa, based in Dublin, supplies the SFL-Handle-ZY to system integrators, fleet operators and maintenance teams across the EU and the DACH region. Robots Europa prepares each quotation individually, arranges delivery to site and provides support once the handheld is in service, so that it arrives matched to the vehicles and the safety concept it is intended to serve.

Background

SEER Robotics and the Robot Brain

SEER Robotics (06106.HK) is a platform-based embodied intelligent robotics company built around what it calls the Robot Brain, and it serves more than 2,500 customers worldwide with intelligent robotics solutions. Its portfolio spans the controllers that guide autonomous mobile robots and the vehicles themselves, from autonomous pallet trucks to counterbalanced forklifts. The handheld belongs to the supporting equipment around those systems, alongside the units listed in our Controllers category. In a modern intralogistics installation, autonomy handles the routine transport work, while equipment of this kind gives people a dependable way to take over when a situation calls for human judgement.

A handheld designed for more than one vehicle type

SEER positions the SFL-Handle-ZY as an all-purpose handheld, compatible with multiple types of vehicle. Rather than serving a single model, it brings together the full set of motions a forklift operator normally needs: forward and reverse travel, left and right steering, lift and lower, forward and backward tilt, forward and backward reach, and fork spacing adjustment, together with a steering analogue signal. The control elements combine self-resetting switches with a potentiometer, and an additional slot for a steering potentiometer is provided, which gives integrators a choice in how proportional steering is implemented on a particular truck. That breadth is what allows one handheld design to serve counterbalanced, reach and pallet-handling vehicles within the same fleet, subject to the integration being confirmed for each vehicle.

Technical Specifications

The manufacturer has not published the box contents, the storage temperature or any limits beyond the operating range, the specific compatible forklift models, the button count and layout, or any certifications; these details are confirmed at quotation.

How does the SFL-Handle-ZY keep manual driving safe?

Taking manual control of a heavy industrial vehicle is precisely the situation in which safety design matters most, and the handheld addresses it on several levels. The emergency stop is dual-channel, and SEER describes a reserved dual-circuit emergency stop design that is synchronised with the emergency stop function of the main controller. In practice this means that pressing the stop on the handheld is intended to act on the vehicle in the same way as the truck's own emergency stop, rather than sending a separate request that software must interpret.

The second layer is the 3-position safety enable switch. Enabling devices of this type are widely used on industrial pendants: motion is permitted only while the operator holds the switch in its middle position, and either releasing it or gripping it hard in a moment of alarm removes the enable. Combined with self-resetting switches, which return to neutral as soon as they are let go, the arrangement means that the truck moves only while the operator is deliberately commanding it. For a safety engineer drafting the risk assessment of an autonomous fleet, these are the features that make a manual override defensible.

Why does a hard-wired I/O connection matter on a forklift handle?

SEER has chosen an I/O interface hard connection for the SFL-Handle-ZY, a design it credits with stable and reliable signal transmission. Commands leave the handheld as I/O signals along a 2.5 m spiral cable and enter the vehicle through a Cnlinko 24PIN aviation connector. There is no radio pairing to manage, no channel to share with other equipment on a busy warehouse floor, and no reliance on a network that might itself be the cause of the vehicle stopping.

That independence is the essence of a recovery tool. When an autonomous truck halts because its main control system has a fault, the operator needs a path to the drives and hydraulics that does not pass through the system that has just failed. A direct I/O link is the most straightforward way to provide it. The spiral cable allows the operator to stand clear of the vehicle and the load while keeping sight of the forks, and the aviation connector gives a locking, robust interface that suits plugging and unplugging during maintenance rounds.

Who is the SFL-Handle-ZY for?

The first group of buyers is system integrators who commission autonomous forklifts. During mapping, calibration and the teaching of pick-up and drop-off positions, engineers frequently need to drive a truck by hand, and a handheld that covers travel, steering and every mast function shortens that work considerably. Integrators building fleets around SEER vehicles such as the SEER Robotics 2000 Kg Autonomous Counterbalance Truck - EU Model (SCB-2000EU) or the SEER Robotics 3000 Kg Autonomous Counterbalance Truck - EU Model (SCB-3000EU) will naturally consider it, although compatibility with any particular truck is confirmed with Robots Europa before an order is placed.

The second group is operators and maintenance teams responsible for fleets already in service, who need a reliable means of recovering a stranded vehicle and moving it to a service area. The third is manufacturers and engineering teams converting conventional forklifts to autonomous operation, for whom the additional steering potentiometer slot and the I/O control logic offer flexibility when adapting the handheld to their own vehicle control. Readers comparing wider automation options will find further vehicles in our Factory Robots category.

What is the SFL-Handle-ZY used for?

1. Commissioning: driving a new autonomous truck by hand while maps, routes and load stations are set up.
2. Vehicle recovery: moving a halted forklift out of an aisle when its main control system is unavailable.
3. Fine positioning: inching the forks, mast and reach mechanism precisely during calibration of pick-up points.
4. Maintenance moves: repositioning vehicles into service bays or charging areas without restarting autonomous operation.
5. Retrofit projects: giving converted conventional forklifts a manual control path alongside their new automation.
6. Safety testing: verifying emergency stop behaviour and enabling functions as part of site acceptance procedures.

Summary

Autonomy carries the routine work of a modern warehouse, but every fleet still needs a dependable way for a person to take the controls. The SFL-Handle-ZY provides that way in a single compact unit: the complete set of travel, steering and mast functions, a hard-wired I/O link that does not depend on the system it may need to override, and a dual-channel emergency stop working alongside a 3-position enable switch to keep manual driving deliberate and controlled. For integrators commissioning new trucks, for teams recovering stranded vehicles and for engineers converting conventional forklifts, it is the cable in the operator's hand that keeps the whole system recoverable.
