1:00 pm – 5:00 pm

3:44 – Today will be the last time we meet as a team since we will be going on break. The next time we will be together as a team will be next Wednesday after the break. From then, until it is time to bag the robot, we will be meeting every day that we can to test out the robot. The lift still needs to be perfected and mounted onto the robot. In addition, we are working on finding a way to get our robot onto the six-inch platform. We will most likely use pneumatics to push the front of the robot up on an angle so the front wheels can roll onto the platform. Then, once the front of the robot has boarded the platform, we will deploy a back set of pneumatic so the robot can be horizontal instead of at an angle. This will then allow us to drive our robot onto the platform. In order to limit friction, we will attach a wheel underneath each pneumatic.

Eric reverted the code to a previous version due to compatibility issues. He then spent some time re-adding features that had been removed, and adding new functionality. He also worked with the build team to get the lift motor into working condition.

Johanna is securing the motor on the top of the lift. She did this by creating a bracket out of aluminum. She then attached this bracket onto the gearbox with screws. Now that the motor is secured to the lift, as the shaft in the motor spins and rotates the chain, the motor itself will stay stationary. Nathan was able to give her some guidance through this process.

Nickel was able to create and attach a hook for the lift. He made the hook out of aluminum C channel and then attached the hook onto the chain. He noticed that our chain tensioner is providing too much tension and that our motor does not have enough torque to overcome that tension. In addition to this, we noticed that the motor was not strong enough to lift the hatch panel. Nickel is ordering a new planetary production gear in hopes of resolving this issue.

Bubs and Richard are planning and designing a way for the robot to climb the six inch platform. They are planning on using four pistons that will push down a set of wheels in the back and in the front. They will board the platform backwards due to the amount of weight on the back with the battery and the electronics. The wheels that the pistons push down will be non-powered and will retract when a certain amount of the robot has made it on to the 6 inch habitat zone. The two sets of wheels/ pistons will work independently from each other meaning that the front will activate first and then the front allowing for the robot to get on the platform. The wheels are omni wheels allowing the robot to readjust to the platform if the robot is not centered.
