Last four weeks - 08/19- 09/13/2019 It is been a month since the last post, but we keep working. We have been busy these last weeks and the purpose of this post is to summarize the work done. At this point in the summer, we spend most of our time working in collaboration with Bill James from Jpods. Our work on the 1/12th scale ended on several propositions of designs and mechanisms. We proposed interested solutions to deal with the gap and 3 different approches for the switch. All of that is accessible in the last post and will be explained with more details in our report. We hope that our work will be helpfull for the new teams in their projects. We spend time to introduce some of them to work done and issues met. Jacques-Hariel has worked with Bill, Ron and David on the suitcase scale system. We made several improvement on the model we shown in the last post (Fith & Sixth weeks). We learnt from the mistakes we made on the first track and Bill designed the new track
