As we wrap up Week 3 of build season, we have accomplished many tasks throughout the team. These include new mechanical features, programming improvements, CAD developments and the switch from a joystick to an Xbox controller.
Mechanical:
We disassembled the sprockets on Fredrick IV (Last years Robot) and put them onto "Elon" (This years robot).
We also built the grabbing mechanism on the arm of practice bot for "Elon". Now we are working on a way to allow the arm to fit back into the parameters of the robot once it is released.
Programming:
While working with the encoders for the practice bot we discovered that each encoder for each gearbox was giving off a different output of approx. 1,000 points compared to each other. We disassembled the gearboxes and discovered that each was set at a different ratio. We adjusted for this and reassembled the gearboxes. Now the output values are within 100 points of each other and we are continuing to narrow this gap. We added a button switch as well to stop the motors once the ball enters inside the arms and are working on adding a gyro that will regulate the variance in the encoders.
CAD:
CAD has made many breakthroughs as well. We have designed a more detailed and in depth look at the robot as well as completing the grabbing mechanism for the arm. Now we are working for a design that will allow for the arm to retract into the parameters of the robot.
Joystick to Controller:
We have decided to switch from our previous controlling device, the joystick to an Xbox controller. We are hoping this will allow for better controlling of the robot and allow for a more successful year.
