Build: EV3 Gripper

This model can drive, take various objects, lift them up and transport. It is compact, steady and strong. It can be used in various games and challenges. I built and programmed three versions of this model:

Operated by Sony PlayStation controller: https://www.youtube.com/watch?v=7cf6XKnYFE0
A gaming controller allows precisely control the robot and even play dynamic games such as robotic basketball shown on the video. This version is shown on pictures 2-5.
Autonomous, programmed using LEGO MINDSTORMS EV3 software: https://www.youtube.com/watch?v=tUhcIIF8Xcg
On this video the robot completes tasks on 8'x8' layout. The logic based on data from ultrasonic sensor, gyro sensor, two color sensors and motor rotation sensors makes it very accurate. A piece of wood is placed on the back side of the robot to prevent it from flipping over when carrying a heavy block.
Voice controlled using Amazon Alexa: https://www.youtube.com/watch?v=_DEuCIV-frI This version is shown on the first picture.
