Cliff sensor reflector

thingiverse

I purchased an AGDA Robotic vacuum cleaner that refused to clean my kitchen floor, hastily retreating from the kitchen at top speed as if it feared plummeting off a precipice. A web search revealed several key points: this machine appears to be one of many manufactured in China by Lilin (http://www.robotvacuumcleaner.cn/), and it shares similarities with the more widely recognized brand Roomba. There are numerous complaints from consumers regarding Roomba vacuum cleaners that mistakenly perceive dark colors as a deep chasm, causing them to reverse direction. I attempted to alleviate this issue by applying masking tape over the sensor, as suggested in various online forums, but discovered that these sensors on my unit require a gap for light transmission. After finding that a piece of bent white card taped in place resolved the problem, I decided to design and create a custom plastic component to serve the same purpose. Since my home is situated on one level, I will eventually secure these reflectors in place once the warranty expires on the cleaner. If you encounter the same issue with the same sensors, try installing these reflectors, but take full responsibility for any potential consequences if your vacuum cleaner slips and falls down stairs. Print Settings: Printer: Flux Delta Rafts: No Supports: No Resolution: 0.15 Infill: 20% Notes: Designed using Autodesk 123Design. I utilized white PLA material, which I assume will also effectively reflect infrared light in other colors. You will need to cover all four sensors with these reflectors. The cliff sensors measure 27mm by 6.5mm.
