CocoRobo




“Design, Create, Inspire.”


CocoRobo is an EdTech company I co-founded with my friend Tony in 2016. Based in Hong Kong & Shenzhen, we provide a one-stop solution for STEAM education.

My mission as the CTO is to create easy-to-use products, which embody the concept of P.B.L. (Project-based Learning) methodology, for teachers and students in K-12 system, in the hope of bridging the gap between cutting-edge technologies and classrooms.

I lead the Research & Development team, it’s been 4 years since the beginning of my startup life. Now we have developed a series of education technology products 



CocoMod™


a set of plug-and-play electronic modules that provide many functions to help users with zero coding or electronic experience to build their projects. The product series has evolved two generations by this far;

The 1st Generation 


Specification:
Physical Size:
Modules in 40*40mm:
All except for the Horizontal Adapting Module
Horizontal Adapting Module: 92*40mm


Processor:
Main Controller:
ATMega32u4 (8-bit AVR Microcontrollers)
WiFi Module:
Espressif ESP8266 (L106 32-bit RISC core)


Input/Output:
UART, Software Serial, Digital & Analog I/O, SPI, I²C, I²S


Display (Screen Module):
RGB OLED Screen with 128*128 px of resolution.
Wireless Features:
Bluetooth 2.0 (Bluetooth Module)
IEEE 802.11 b/g/n Wi-F (Wi-Fi Module)

Programming Language:
CocoBlockly Arduino Mode or Arduino IDE,
Connect to computer using MicroUSB to USB cable via web browser.


Connector:
Double-slot B2B Connector

Power:
5V DC

The 1st Generation is dedicated to serving as part of our STEAM education solution. The main controller is based on an ATMega32U4 chip; we developed over 15+ sensors and modules to make it compatible with our main controller module. Since it’s an Arduino-based board, user can also embed other third-party modules to our hardware, as long as they can support I²C, SPI or UART communication. Read more in our online help website 



The 2nd Generation: “CocoRobo X”


Specification:
Physical Size:
Modules in 45*45mm: All excepted for Camera Module and Gamepad Module
Camera Module: 20*25mm
Gamepad Module: 108*45mm

Processor:

CocoBlockly X or MicroPython,
Connect to computer using MicroUSB to USB cable via web browser.

Connector:
Single-slot B2B Connector


Power:
3.3V DC
The 2nd Generation is dedicated to serving as part of our AI STEM education solution, and the main controllers of this series are separated into two parts: the I.o.T. module and the A.I. Module. The I.o.T module is based on Espressif ESP32 chip, and the A.I. Module is based on Kendryte K210 chip that can provide 1TOPS computing power in low power mode. Our 2nd Generation product is able to bring many robust features to the K-12 classroom in just 45mm×45mm size through our Blockly programming environment—features like OpenMV implementation, Machine Learning Model Inference, Object Classifier, Speech Recognition, etc.



 We also provide product kits in versatile themes: Music & Light, H.C.I., Robotics, I.o.T., A.I.. All of the product kits come with different types of mechanical parts (Laser cutting board) to help the user to build a complete project.



CocoBlockly™



CocoBlockly is an online visual programming environment that enables users to code through a web browser. Based on Google Blockly, we have developed a various version for four programming languages: 




CocoCloud™



CocoCloud is a cloud platform for data gathering and visualizations.




CocoEducation™



CocoRobo Education is an online education platform for K-12 schools that are using our products and services.




Milestone


We have established collaboration with over 200 schools in the Greater Bay Area across Hong Kong, Shenzhen, Macao, and Guangzhou. Apart from K12 schools, CocoRobo is currently collaborating with NIES (National Institute of Education Sciences) and professors at SCNU to write AI curriculum for elementary and secondary school with products and service from CocoRobo.

We hosted various school-wide robot competitions in Hong Kong with business partners like China Mobile HK. For each competition, approximately 30~40 schools have attended.


At the early stage, we were supported by a government funding called TSSSU from the Chinese University of Hong Kong and Hong Kong S.A.R. Afterwards, we have successfully secured two rounds of Angel funds invested by InnoHK, Saltagen Canada, and Particle X.

Since I was a professional designer before, I managed to design a coconut-like logomark with a talking buttle inside it :D
