More Claws, More Journaling
Work Groups will continue to troubleshoot their robots. This means the robot must be pretty quick and needs to have a motorized claw that grasps a soda can. These activities always sound simple and are very easy to do poorly.
Here are some observations from last week:
1.) The first attempts of attaching the claws to the robots looked clumsy and did not work very well. That is what I expected.
2.) More students were adding better quality notes to their journals. That is what I had I hoped for.
3.) Many of the robots got very heavy. That was not as predictable but I was not surprised.
4.) The gear trains were designed by using shortcuts. I thought I would see more gear trains designed better because we spent so much time on the dragsters and learning gear trains. I thought groups would use that information to their advantage when trying to design a robot for this task. You earned that knowledge from hard work. This surprised me.
5.) There was a lot of re-designing going on. I saw many more students willing to tear apart what they were building to fix a problem. That is what you should be doing.
Groups should be ready to run their robot and grasp a can by the end of the week.
I would like to see each student start a blog journal so that you can write and publish your work to the web.
