So, today was a productive day for the build team. Right after school, Anne, Nandini and I went over to IDEO to talk to Jimmy about brush options and construction of the chassis. Yesterday, Doug purchased some large brooms of varying bristle stiffnesses for us to prototype with. We showed these to Jimmy and then returned to school and prototyped with them. It looks like we will be using the softer-bristled red broom. We split the broom in half and put the pieces back-to-back with a pole in the middle, which was then attached to the drill. This was surprusingly effective at moving the ball up the full-scale prototype ramp we created. From this prototype, we learned that we will only need one front brush to bring the balls in. We also fine-tuned the dimensions for the ramp so that when the chassis is done we can start working right away on the construction of the ramp/brush device. Tomorrow I am planning on heading over to Home Depot to buy some more brooms.
As for programming, Karlin explained traction control and how we can implement it on our robot using encoders and an accelerometer.
A lot of people have been wondering about going over to IDEO. This year, since Emily no longer works there, we will be going over a lot less. We will be doing most of our work at Castilleja. However, we will need to test code and install the electronics board at IDEO, so a few people may go over then. We will work out a system so that everyone who wants to see the shop can go over at some point during the season.
That's all for now. See you tomorrow at 5:15.
