Robot's description

Our robot uses 4 sensors :

Ultrasound sensor

Gyroscope

Touch sensor

Color sensor

And 3 actuators:

2 tacho motors for both wheels

1 tacho motor we used for the grabing arm

Once we had built the base of our robot from the guide, we realized there were some issues that were not covered by our first construction:

Construction Tricks

Apart from the robot itself, which we built from the guide, we added some parts we built thanks to tricks:

Automated arm

We made an arm with specific obligations: The rest of the robot was already built, and we needed to be able to grab and release a little object (5-10 cms). Thus we needed to find a solution with a constrain a place. That is why we came up with a arm that goes from the top of the robot to the ground, in order to be able to block an item and to release it easily

Hit detector

After some tests, we realized our robot was weak on the side: if the obstacle was not exactly in front of him, he could not detect it. We thought about a solution with a push sensor, but we could use only one more sensor.
First, we met issues with the sensor getting blocked when not pushed perfectly straight, thus, we came up with a solution involving gears in order to get a good transmission of forces.
