Will Cogley's DIY Desktop Companion for Makers. Support our kickstarter to allow us to keep improving Coglet and so we can offer all components in one place! https://www.kickstarter.com/projects/willcogley/coglet-open-source-3d-printable-robot-companion-kit
Refer to the build video. For further reading and troubleshooting, refer to the translated docs in this repo.
PCB (CogNog V1.0):
- USB socket for RP2040 is tight - requires a slim USB-C cable
- ESP Camera socket too close to other components
- In general needs more bulk capacitance to manage power dips
- Mic socket too close to ESP
- Camera will not work with default pins and simultaneously use tasks requiring PSRAM - must rewire the following ESP pins and use camera-version branch of CogletESP
- 35->14
- 36->41
- 37->42
- Mouth pin is on pin 19 - the final slot - which is unintuitive
- Camera feed for ESP32 Cam is horizontally flipped!
Mechanical
- Servos are too tight generally - we are working on finding a better servo supplier
- There are some sub-optimal snap-fits which will be converted to use screws at some point
- On lower quality PLA the servos can lose grip by stripping away the plastic
Consider backing our kickstarter so we can provide all the parts in one place!
