RoboSapien Media. First impression: It looks like a children's toy because it is big, bulky and plastic. But when it comes to life, it is extremely loud. This robot has a built-in camera and a small LCD screen on its chest. Apart from that, it stores images, plays music, videos or voice files on an SD card.
Lego Mindstorms. Very challenging and advanced! This is what you would least expect from Lego because when we hear "Lego", we instantly think of those little plastic building blocks we put together. This is somehow different. It is like building your first basic robot from scratch, program it and make it do what you want! You can also create thousands of other robotic inventions. Mindstorms include an "intelligent brick"- the program brain of the robot, "sound sensor" - the robot reacts to your sound command, "ultrasonic sensor"- makes the robot measure distance, and the "interactive servo motors"- makes the robot walk and move. It has four different sensors and three servomotors. One best feature is that USB or Bluetooth downloads the programme to the robot's processing brick for convenience. It is satisfying and complex especially if you have programmed it yourself. The packaging states that Mindstorms is for anyone above the age of 10. Personally, this is only for people with broad computer knowledge because you will find that it is slightly complicated. However, this is one big challenge that Lego has created and I am positive that it will sell in today's market.
On the scale, I would choose Lego Mindstorms among the three because it is such a complete and brilliant invention, which you really put your mind into. The technology is so advanced that Lego Mindstorms is not just your regular robot and that's why we have one in our living room. But take your pick from my list and see them come to life.
