Cat Rover

thingiverse

Cat Rover is a Raspberry Pi based three-wheeled robotic platform that controls itself through Wi-Fi connectivity and an intuitive custom web interface engineered for low latency performance. Two high-precision ST28 stepper motors with onboard drivers power the system alongside a versatile USB webcam and built-in room for battery installation. A compact, stationary wheel design featuring a fixed front wheel attached to a rotating hub allows for effortless movement across various surfaces. Those using a rotating wheel can easily attach it directly to the base structure without modification. Key component manufacturers include http://www.thingiverse.com/thing:862438; multiple wheel designs can be integrated into this platform. Convenient attachment points for components are offered via threaded fasteners and flexible cable ties, streamlining the build process. The car's front panel boasts built-in mounts for copper tape-based charging interfaces compatible with included docking systems. Users may hot glue springs to the charger dock's receptacles, linking them to a battery-powered power source. Technical information can be found at https://github.com/jsalin/catrover and accompanying assembly instructions. Printing settings for this build include: * Printer: Velleman K8200 * Rafts: No * Supports: No * Resolution: 0.18mm * Infill Percentage: 10% Printers should utilize at least a 0.35 nozzle; the current setting results in well-defined details. Using perimeter width of no less than 5 will also ensure robust construction for all moving components, especially those supporting the motor mounts. Cat Rover's underlying architecture consists of parts carefully designed within SolidWorks 2013 and exported into standard STL files. Currently functional, Cat Rover showcases exceptional performance using the integrated ST28 stepper motors. However, to improve mobility over textured surfaces like carpets, developers are actively developing a successor known as Cat Rover 2 – further project details can be discovered on http://thingiverse.com.
