A remote-controlled car equipped with a scooping/raking mechanism to collect dog poop. The design evolved through multiple iterations: Initial Ideas: Front-Opening Design: The front of the car would descend to form a ramp, and a rake would pull the poop in. Bottom-Opening Design: A grabber arm descends through a bottom hatch to collect the poop. Final Implementation: Adopted the front-opening design with a hinged box structure. Created a lightweight rake mechanism operated by two motors for both linear and rotational motion. Laser-cut plywood was used for building the final design. Programmed motor movements via Arduino. System was mounted on an RC car chassis.  

Constraints: Regular maintenance and cleaning of the vehicle is required for hygiene. Limited range of the remote control must be considered. Idea Brainstorming: Dog Harness Alarm: Detects when the dog is about to defecate and alerts the owner via buzzer. Phone App: Uses the phone camera to monitor if the dog is defecating. RC Poop Collector: An autonomous vehicle that gathers poop twice a day. Skills Applied: CAD Electronics Design Thinking Programming
