Chrissy and Julia made a run to Ace Hardware during period 6 today and bought door hinges, wheel axle/bolts (6″) and nylon nuts to go along with them, steel (?) cable, washers, and maybe a few other things… When Ed came, he brought more steel cable, crimps for the cable, and eye-bolts (I don’t actually know what these are called).
The proto chassis now has wheels and a ramp (pictures coming)! The ramp is made out of foamcore mounted on spring hinges and has a damper/support-component, too. Watch the magic unfold…and the foam core break apart. It’s not a big deal, but it means we’ve entered the next stage in the ramp prototyping process: creating an 80-20 frame for the ramp. Not only will this give us a much more realistic sense of weight, it also will make for a much more durable product.
There’s also a lot to be done in every other area of the robot–the arm/tower and chassis. Ed helped us break these to-dos into separate tasks with deadlines (see the white board), and we’ll each be focusing on two of these for the next while.
And, finally, Kersten learned the importance of “saftey”.
