From the project
Autonomous line-following rescue robot built for a competition at Waterloo's IDEAS Clinic. Raspberry Pi Pico and Arduino Mega, Pixy2 vision, custom KiCad PCBs.
An autonomous line-following rescue robot, built for a competition at the University of Waterloo's IDEAS Clinic. It follows a track, finds a coloured target, picks it up with a servo claw, carries it to a safe zone, drops it, then finds the line again and drives back.
We called it Hamster, which is why the robot code lives in Hamster/.
Built by Josh Lobe, Koketso Gaborekwe, Luke Zhang, Winters Xia, and Griffin Wilson.

MegaShield: common questions
How big is the MegaShield PCB?
The MegaShield measures 101.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MegaShield?
18 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the MegaShield design files?
From the LukeZhang0826/RescueRobot repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the MegaShield design in my own project?
The repository has no license, so all rights stay with LukeZhang0826. Use it as a reference, and ask the author before reusing the design.
