SAFETY FEATURES

At WCB Robotics, safety is a key consideration in the design of ELMO (Enhanced Lightweight Mobile Operator), our autonomous façade-cleaning robot. Designed to operate on exterior glass surfaces at significant heights, ELMO incorporates multiple safety mechanisms to monitor operating conditions, support controlled movement, and address the challenges associated with high-rise façade cleaning.

Intelligent Control and Monitoring

ELMO uses an advanced microcontroller-based control system to monitor operating conditions and respond to critical parameters. Its control architecture incorporates safety mechanisms designed to support stability, detect abnormal operating conditions, and help maintain controlled movement during operation.

Tethering as an Additional Safety Measure

ELMO incorporates a safety tether as an additional layer of protection during operation. Secured to an appropriate anchoring point, the tether serves as a secondary safeguard in the event of an unexpected failure. It is designed to provide additional protection rather than bear the robot’s weight during normal operation.

Redundancy and Backup Systems

ELMO incorporates redundant control circuitry designed to provide an alternative control path in the event of a primary circuit failure. Its primary and backup power systems support operational continuity and return-to-home functionality. These features are designed to help manage specific component failures and support reliable operation.

Connectivity and Predictive Maintenance

Wi-Fi connectivity enables remote monitoring and operational data collection where network access is available. This information can help assess usage patterns, track system performance, and identify potential maintenance requirements. Operational insights can also support maintenance planning and spare-parts management, helping reduce unexpected downtime.

A Safety-Focused Approach to Façade Automation

ELMO combines lightweight engineering, proprietary suction technology, sensor-based monitoring, redundant systems, and tether protection to address the challenges of high-rise glass façade cleaning. Weighing just 16 kg and tested in wind speeds of up to 80 km/h, the robot is designed to support efficient façade maintenance across demanding operating environments.

At WCB Robotics, our focus is on developing practical robotic solutions that reduce human exposure to hazardous working conditions. Through ELMO, we aim to advance façade-cleaning automation while enabling people to focus on supervision, maintenance, and other skilled activities.
