This is the v2 version, I redisigned its shape to look more cozmo-ish. Functionalities are mostly the same as Cozmars v1 here https://www.thingiverse.com/thing:4657644 Still using rpi zero w and its compatable camera, but the board is so expensive, almost doubled the price in the last 2 years. doc: https://rcute-cozmars.readthedocs.io/zh_CN/latest/ demo : https://www.bilibili.com/video/BV11v411H7HE?share_source=copy_web build detail: https://github.com/r-cute/rcute-cozmars-server/tree/dev-v2 client SDK: https://github.com/r-cute/rcute-cozmars/ ** It's not easy to build. and I bought all the electronic parts below from Taobao, which may not be accessable in your country ** You may want to change the design to adapt to your e-parts of different size, please share your remix. 3d model: https://github.com/r-cute/rcute-cozmars-model-v2/ ### E-parts * raspberry pi zero w and camera * 9g plastic blue servo X3 * PCA9685 16-channel servo driver with capacitor (bend straight the 90° pins) * 1.14 inch color display [link](https://item.taobao.com/item.htm?spm=a230r.1.14.64.3ca81e571WbCh8&id=597476360924&ns=1&abbucket=2#detail) * 3v 15r/m N20 motor X2 [link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.5c202e8dm3jWG3&id=525167243889&_u=6mronro79b8) * L298N motor driver [link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.6bfd2e8df7G3Db&id=544440997945&_u=6mronroe9af) * infrared sensor[link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.42ba2e8dhjP0wv&id=587583743573&_u=tmronroba97) * ultrasonic distance sensor with leds(3.3v compatible) [link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.42ba2e8dhjP0wv&id=601436820928&_u=tmronro3c36) * TTP223 touch sensor[link](https://detail.tmall.com/item.htm?id=530631046077&spm=a1z09.2.0.0.42ba2e8dhjP0wv&_u=tmronro6ac0) * 112D on/off power button [link](https://detail.tmall.com/item.htm?spm=a230r.1.14.41.18c45a9ck6404o&id=608231129725&ns=1&abbucket=2) * INMP441 microphone (use 90° pins) [link](https://detail.tmall.com/item.htm?id=585759454132&ali_refid=a3_430582_1006:1106005875:N:721zPr1+SQY0TRxbgmXbD1ttIGZ5/0H4:813d25138077578759dad9000f308b60&ali_trackid=1_813d25138077578759dad9000f308b60&spm=a230r.1.14.1) * 3.7v battery size:10x35x65mm * speaker size:20x35x3.5mm [link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.42ba2e8dZMQ0fI&id=620430156858&_u=tmronro196d) * MAX98357 I2S amp [link](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.42ba2e8d4ehNIY&id=589463924875&_u=tmronro2caf) * and many 10cm wires, use soft silicone wires [link](https://item.taobao.com/item.htm?spm=a230r.1.14.39.4115393a4gMecn&id=564148756752&ns=1&abbucket=2#detail) to connect display Thanks to anyone who wanted to donate, but I don't have paypal account :)
