Story
Raspberry Pi is a series of small single-board computers(SBCs) developed in the United Kingdomby the Raspberry Pi Foundation in association with Broadcom.
The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries.
The original model became more popular than anticipated, selling outside its target market for uses such as robotics.
What is a Raspberry Pi?MarsCat, an AI robot cat created by Elephant Robotics, is powered by Raspberry PI 3 B(wifi)-Quad-Core ARM Cortex-A53 CPU, 1GB ARM. The API includes Type C (Data Transmission), DC JACK (Charging Cable Interface), HDMI. Learn More
Based on the open-source Raspberry PI, Marscat is able to conduct secondary developments according to geeks' novelty ideas.

Followings are the tutorial and Python scripts for further developments based on a Raspberry Pi, which is the basis for MarsCat research.
Preparations- Connect monitor, mouse, keyboard
- Connections: Wifi, ssh, vnc, etc
Account: pi Password: raspberry
- Disable auto-start function before programming:
cd ~/marsai
./tools/stop-systemd-services.sh
./tools/disable-systemd-services.sh- Enable the auto-start function:
cd ~/marsai
./tools/enable-systemd-services.sh
./tools/start-systemd-services.shDownload the API

Testing ProcessConclusionMarsCat, a robot home companion for people, has the potential for scientific research of AI, robotics & Raspberry Pi. The company has released its open-source code on GitHub since the AI cat was created. With a built-in Raspberry Pi, MarsCat is going to be another carnival for geeks sunk into the Raspberry Pi world in the months to come because of its perfect conditions and the ideas to be a part of Raspberry Pi ecology.
