Can the robot navigate around students or unexpected obstacles?

• Geofencing: The system operates within strictly defined GPS boundaries to ensure it stays on designated paths.

• Safety Zones: We program specific "no-go" zones near sensitive areas to ensure the robot never interferes with school activities.

How does using the Smart-Spread change the way custodians manage salting?

• The Shift in Role: Instead of manual, heavy lifting and broadcasting salt by hand, custodians move into a supervisory role.

• Efficiency: The robot handles the repetitive, time-consuming task of clearing long walkways, allowing staff to focus on higher-priority indoor maintenance or complex entryways.

• Precision: Unlike manual spreading, which often results in "heavy spots," the robot ensures a mathematically consistent application across the entire property.

How is the Smart-Spread different from a standard salt spreader?

• GPS Integration: It uses high-precision GPS (99.8% accuracy) to track exactly where salt has been applied, preventing double-salting.

• Anti-Clog Technology: It features a custom-engineered variable-pitch auger that ensures salt flows smoothly even in damp, freezing conditions.

• Smart Brain: The unit is powered by an Arduino-based microcontroller that coordinates sensors and motor output in real-time.

Is this a locally made product?

• Cambridge-Built: Yes. The chassis is machined on a Sienci Labs CNC and drive components are 3D-printed using Bambu Lab technology right in our Cambridge, Ontario workshop.

• Custom Engineering: This isn't an off-the-shelf kit; it is a ground-up design specifically for the Canadian climate.

Environmental & Sustainability FAQs

How does this project help the local environment?

• Salt Reduction: By using precision sensors and a software-controlled auger, we can reduce total salt usage by approximately 30%.

• Watershed Protection: Reducing salt runoff helps protect local vegetation and the Grand River watershed from chemical contamination.

What happens if the robot loses its GPS signal?

• Safety Protocols: The Arduino-based "brain" is programmed with safety overrides to stop or safe-mode the device if it detects a loss of navigation signal or encounters an unplanned obstruction.
