In this project(2013-2015), I and other members from IRC designed a general version of four-feet robot with a steady electrical system. Then based on different creatures, we changed the structure and made them into several kinds of robots, including dog, panda, etc. There are two kinds of material for the robot: Acrylonitrile-butdiene-styrene(abs) and Aluminum alloy. Abs board robot weight light with great mechanical characteristics, Al alloy weight heavier, but more steady for the robot locomotion.
The control system is the same as the small intelligent robot.
Here are two videos, one is panda robot, another is dog.
Beside of those functions, we also added WIFI, vision, voice and other sensors, the following aim is to make it into a great taker of smart home assistant.
