Here is another quadruped robot for more advanced robot enthusiasts. The Kyzen can carry loads up to 2.2lbs, so you can enhance it with additional sensors. It can shift its stance while performing actions, so it can bend down, tilt sideways or lower its body completely.
This robot has 3 cameras on its head to track and recognize faces and colors. It is smart enough to follow its owner. Its Follow me feature relies on vSLAM and YoLo Neural Network human tracking on-board, so there is no need to use WiFi. This robot has max walking speed of 5.5mph. It measures 17 x 15 x 10″.
