Our Robot Design
Flip in Tube
We use a tube to collect the gold and silver materials and to score them in the middle lander. We call it the "flip in tube" because it flips out (when the program starts) so it fits in the sizing cube.
In order to collect and keep materials in the "Flip in Tube", we need to implement some magical zip ties. The zip ties work with a piece of fabric to grab the materials and ensure the materials stay in the collecting tube.
The Latch of Power
Our robot is able to hang on the lander. In order for this to happen, we need to latch on to the middle lander. This axel is powered by a servo that moves. Because we like interesting and creative names, we named it "The Latch of Power".
We noticed that some of the cables that come from the REV Hex Motors can be easily bent. To solve this issue, we designed motor caps in SolidWorks. After we had that designed, we 3-D printed them.
Windshield Wiper Area
Because our arm has a motion spectrum like a windshield wiper, that is why we named the origin of movement how we did. The red pice on the right (by the bigger gear) was another 3-D printed part. That part fastens our main arm gear to the arm c-channel. Another part visible is the arm touch sensor (the black box with the white button). When this button is pressed, the arm is not allowed to move.
The treds that you can see in this image are for helping our robot cross over the craters. The treds are raised above the wheels so they are only running and make contact with the ground when we cross the crater.
We didn't have a very creative name for our holonomic base. Our base (made up of 4 holonomic wheels tilted at 45 degrees) is powered by REV Hex Motors. Our drive base allows a 360 degree range of motion.
