Projects :: Final Project :: NeufKar Robotics
About:
NeufKar's final project was dubbed "POINTLESS" (Political Ordinating Incredulous Navigational Trigometric Logarithm Exasperatingly Supplementary Spontaneous machine). It is a Lego brick sorter, and can differentiate between blue and red coloured bricks.
Process:
To operate, you begin by first placing one brick at a time on the main conveyor belt. Then, the robot will read it through a light sensor, and it will be placed on the appropriate secondary conveyor belt, depending on the colour. The robot will then detect when the brick has gone off the conveyor belt and into a small container. Everything is automatic, except for placing the brick on the conveyor belt.
The Robot Itself:
The robot contains many, many pieces. There are parts from at least 4 different cases. The more important parts are listed below:
Problems:
We've encountered many difficulties with designing this robot. The foremost of which was the 'auto loader'. The robot was supposed to be able to automatically drop one brick at a time onto the main conveyor belt. The idea was simple, to place many brick into a chute and the robot will, via two wheels spinning inwards, towards each other, drop out a brick at a time. There would be a light sensor just in between the two motors to control them. The problem was, a, the chute took a whole class to make, and b, the light sensor values were jumping all over the place, even with a light to stabilize the value, and therefore would have been extremely difficult to program. With only 1.2 classes left, we decided to scrap the auto loader and go for the manual. Please note that this is still possible, just not within our limited time frame.
More problems. Note: Most, if not all of these problems have been fixed.
