The planterbot is a plant monitoring robot. It uses capacitance for sensing moisture from the plant instead of using the usual soil probe, this means that wires don’t go into the plant. It also detects temperature and light using thermistors and Cds photocells and displays the temperature and light graphically on the front facing LCD. [ ]

Line Follower Robot Sensor Concept - Sensor line detector is used in line follower robot is usually based on the principle of light reflectionto distinguish the line with the background color. In the dark color of the light absorption is greater than that of white light reflected to the sensor becomes smaller. Position sensor to track the trajectory and the example circuit. Line Follower Robot  Sensor  Concept Light used for the introduction of the line is usually visible light and infra-red. Sensors for visible light are commonly used are LDR (Light Depending Resistance), while for the infrared light is atransistor and photo diode (photodiode). Sensors placed at the bottom of the frame to hang the robot, so that its position can be located just above the track to be read.

This is a question that many people have currently as robotic cars begin to become more of a reality in the modern world. Whether it's the one being developed by Google or all the other automatic vehicles that are being developed, it's a very exciting time to be alive if you love technology. Still, many people wonder if computers can replace humans as drivers and do a better job. Over at the MIT Technology Review, they've taken a closer look at this problem.

He made the announcement at a robotics conference this summer in Santa Clara, California. Read More.....
