viBOT

viBOT is viAct's computer vision-powered agile mobile robot, designed to move autonomously through challenging and dynamic construction environments, carrying out safety monitoring, remote inspections, and progress documentation without requiring a human operator to accompany it.

A site is always larger than the team monitoring it. A safety officer can be in one place at one time. A fixed camera covers one angle. A scheduled inspection covers one moment. The areas not covered by cameras, the hours between walkthroughs, the zones too hazardous or inconvenient for frequent manual patrols, are where risks accumulate undetected.

viBOT closes these gaps by moving through the site continuously, autonomously, carrying multiple AI modules that detect safety violations in real time, capturing 360° documentation as it goes, and operating without fatigue, shift constraints, or supervision.

For EHS teams specifically, the value is threefold:

• First, viBOT extends monitoring coverage to areas and timeframes that manual safety patrols and fixed cameras do not reach.
  

• Second, it removes the personal risk of sending a safety officer into a hazardous or difficult-access area for inspection.
  

• Third, it generates a continuous, timestamped documentary record of site conditions, not a snapshot taken once a week, but an evolving record that reflects the site as it actually is across every shift.

The result, verified from viAct's deployments: 80% reduction in fatal injuries on viBOT-monitored construction sites.

This is an important distinction to get right because fixed AI cameras also offer remote monitoring via viHUB. The difference between remote camera monitoring and viBOT's remote inspection capability is not just about seeing, it is about control.

A fixed camera gives EHS teams the remote visibility of a pre-determined position. They can watch what is happening in front of that camera from anywhere, but cannot change what the camera sees, redirect it to investigate something they noticed, or send it to a specific area that has no camera coverage.

viBOT, on the other hand, gives remote control of where to look and what to investigate:

• Redirect mid-patrol: If a site manager reviewing the live feed notices something unusual in a specific area, they can redirect viBOT to that location instantly from anywhere

• Dynamic ground-level coverage: viBOT moves through the site, capturing footage from angles and positions that no fixed camera was installed to cover, including areas that change as the construction programme progresses

• On-demand inspection dispatch: Instead of waiting for a scheduled site walkthrough, a manager can deploy viBOT to inspect a specific zone, floor level, or work area at any time without anyone needing to physically travel to the site

• Live feed with AI analysis: The remote view is not just raw footage. AI modules on viBOT run continuously during patrol, meaning the site manager sees an actively analysed view, not just a video stream

The practical outcome: project managers and EHS leaders can make informed, real-time decisions about site conditions without being physically present and without being limited to whatever the fixed camera network happens to be pointing at.

viBOT runs multiple AI safety modules simultaneously during every patrol, covering both personal safety compliance and hazard detection in one pass:

Personal safety compliance:

• PPE Non-compliance Detection: Identifying workers without hard hats, safety vests, or other required protective equipment as it moves through the site

• Smoking Detection: Flagging smoking in prohibited zones where fire or explosion risk makes it a serious safety violation

• Social Distancing Detection: Monitoring worker proximity in areas where distancing requirements apply

Hazard and incident detection:

• Worker Fall Down Detection: Detecting a worker fall event in real time and triggering immediate alerts to supervisors and EHS teams

• Falling Object Detection: Identifying objects falling from height, which is one of the most common causes of construction fatalities

• Danger Zone Intrusion Detection: Detecting unauthorised worker entry into restricted or hazardous zones as viBOT patrols the area

Alert mechanism: When any violation or hazard is detected, viBOT responds on two levels simultaneously.

• An on-site sound and lighting alarm is triggered to alert nearby workers immediately.

• Instant notifications are sent to all designated stakeholders, like supervisors, EHS teams, and project managers, via instant messaging app and email, along with the relevant footage and violation detail.

Manual progress documentation on a construction site is one of the most resource-intensive and least reliable processes in project management. It depends on a person walking down the site, taking photographs at specific points, recording observations, and compiling reports. This process is time-consuming, inconsistent between individuals, and captures a fraction of what actually happened on site that day.

viBOT automates this entirely. As it patrols, viBOT autonomously captures 360° images and videos across the jobsite, covering every area it passes through, and not just the spots a photographer remembered to document.

What this means for progress tracking and quality management:

• Continuous Visual Record: Every patrol generates a comprehensive, time-stamped visual record of site conditions, which are not weekly snapshots, but a rolling documentary of how the site is developing shift by shift

• Cloud-based Smart Insights: Captured footage and images are simultaneously recorded in cloud-based document repositories, making them immediately accessible to project managers, consultants, and clients without waiting for a site visit or report compilation

• Progress Verification: 360° documentation from successive patrols creates a time-based visual comparison, making it straightforward to verify whether specific works were completed as programmed, or identify where progress has stalled

Quality Evidence Trail: Having continuous visual documentation of installed works provides an audit trail for quality disputes, insurance claims, and contractual progress milestones. that is far more reliable evidence than manually compiled records

Yes. viBOT is integrated with a 3D scanner and an automated site scanning programme, enabling it to create digital twins of construction jobsites as it patrols.

A construction digital twin is a continuously updated 3D representation of the site as it actually exists. When the digital twin is compared against the approved design or BIM model, discrepancies between what was designed and what was installed become immediately visible.

This is where rework prevention happens. Rework is typically identified late: during a client inspection, a quality audit, or when the next trade arrives and finds the preceding work does not match what they were expecting. By that point, the cost of fixing it has multiplied.

viBOT's digital twin identifies these discrepancies earlier during the construction process. When the 3D scan of installed works is compared to the design model and a deviation is detected, the project team can investigate and correct it before additional works are built on top of a mistake. The earlier a rework issue is caught, the lower the cost and programme impact of resolving it.

For project teams managing complex structures, tight programmes, or high-value contracts where rework penalties apply, this capability directly protects both margin and schedule.

viBOT is designed for both fully autonomous operation and offline environments.

No human operator required: viBOT operates with a high degree of autonomy and does not require human supervision to carry out its missions. Once a patrol route or inspection mission is assigned, it navigates independently through the site, avoiding obstacles, covering its designated areas, and running AI detection continuously without anyone walking alongside it or remotely controlling it in real-time. This is what makes it genuinely useful on a large, active construction site: it does not consume human attention to function.

Offline operation: Each viBOT can autonomously patrol for up to 6 hours and complete its appointed missions even when offline, without internet connectivity. This is critical for construction environments where reliable connectivity cannot be guaranteed across the full site, particularly in underground works, basement levels, tunnel sections, and remote site areas where network signal is weak or absent. Safety monitoring does not pause because the connection dropped.

Automatic recharging: When a patrol mission is complete or battery levels require attention, viBOT navigates autonomously to the nearest base station and packs itself in for recharging, without any human intervention required. This closes the operational loop: deploy, patrol, detect, document, recharge, repeat, continuously and independently.

Each of viAct's three monitoring layers operates in a different spatial domain. Understanding the distinction is what determines which one a site needs and why they complement rather than duplicate each other.

Fixed AI cameras cover defined positions at fixed angles. They provide continuous, always-on monitoring of specific known hazard zones, like crane lift areas, site entrances, excavation edges and they do this reliably and cost-effectively. Their structural limit is that they can only see what they were installed to see. A blind spot, an area that changes as the construction programme progresses, or a zone added mid-project is outside their coverage.

viAER drone covers the aerial layer, facades, rooftops, elevated structures, and large-scale aerial mapping. It provides coverage that no ground-level system can replicate for vertical structures and areas viewed best from above. Its constraint is that it operates in the air, it cannot maintain a continuous ground-level presence.

viBOT covers the dynamic ground layer, moving through the site at ground level, reaching areas that fixed cameras do not cover and drones cannot access, including indoor spaces, basement levels, and areas that shift as the construction programme advances. It is the layer that follows the work as it happens, rather than monitoring fixed positions.

The practical framing: a site chooses based on its specific coverage gaps. A site with comprehensive fixed camera coverage may add viBOT for ground-level patrol of camera blind spots. A high-rise project may prioritise viAER for facade monitoring. A large-footprint site with dynamic, constantly changing activity areas benefits most from viBOT's autonomous mobility. The three are designed to work together when the coverage requirement demands it, but each stand on its own for the specific domain it covers.

viBOT is designed for construction environments where the combination of site scale, dynamic layout, and hazard complexity makes fixed monitoring infrastructure insufficient on its own:

• Large-footprint construction sites: Infrastructure projects, highway construction, large residential developments, and airport works, where the site area exceeds what any fixed camera network can cover comprehensively and manual patrol is resource-intensive
  

• Multi-level and high-rise construction: Where works progress across many floors simultaneously, each requiring safety monitoring, progress documentation, and quality verification, and where sending a safety officer to every level every shift is impractical
  

• Underground and basement work: Tunnel sections, basement excavations, and underground utility corridors where camera installation is impractical and manual patrol carries personal risk
  

• Remote and hard-to-access areas: Site sections in early development stages where infrastructure has not yet been established, or areas with limited access where sending personnel for routine inspection is operationally inefficient
  

• Rapidly changing site layouts: Active construction sites where the work programme changes weekly, like new zones open, others close, hazard points shift, and fixed camera coverage cannot keep pace with where the risk actually is

viBOT is currently deployed across construction projects in Hong Kong, Singapore, and the GCC, covering public housing, infrastructure, commercial development, and industrial construction environments. It is also open for new market expansion based on demand. Talk to sales to know more.

viBOT is engineered specifically for the operational demands of active construction environments that are dynamic, unpredictable, and often without reliable infrastructure. The performance capability that defines viBOT's practical deployment is its autonomous patrol duration of up to 6 hours per mission, which covers a full working shift without requiring recharging or human intervention mid-patrol.

Beyond battery endurance, viBOT is built to operate in environments that would challenge standard robotics, like navigating autonomously through challenging and dynamic site conditions, adapting to obstacles, uneven terrain, and constantly changing site layouts without needing a pre-mapped or controlled environment. This adaptability is what makes it practically deployable on a live construction site rather than just in a controlled setting.

The platform supports simultaneous deployment of multiple AI modules in a single patrol, meaning safety detection, progress documentation, and hazard monitoring all happen in one pass rather than requiring separate dedicated equipment or separate inspection rounds. When a mission is complete, viBOT navigates autonomously to the nearest base station for recharging, requiring no operator involvement in the transition between patrol cycles.
