Robots

Our Robot!

Today post will be about the robot that we realized.
As you may remember, from where I left you, we had a series of problems with our robot but all of them are, for now, solved, and the only thing that now will bother us is to program of the robot.

The first problem that we faced was the fact that the push coming from the two touch sensors was too great, and unfortunately it lifted the front wheels (the ones that push the robot forward, backward and enable it to turn right and left) so that instead of moving the robot was perfectly still.

The problem was solved by increasing the weight on the front part of the robot, by moving the 'brain' forward.

The second problem revealed itself when the back wheel(the one that makes easier to the robot to turn) started to be unables to moves so that the robot found a lot harder to move.

The problem was apparently solved when we did increased the length on the rod that was holding the wheel so that every movement was enough strong to move and direct the wheel.

However the problem was not solved at all, because when the robot turned more that 90 degrees the back wheel and a part of its rod touched one of the front wheel,
making the robot unable to turn.

As you may know with the help of Luca the problem was ended.
In fact we changed the back wheel and its rod into a single sphere, that not only did not created problems but was even more efficient by reducing the friction!

So for now thats all.
