Seventh weeks - 08/12- 08/16/2019

This week we had a meeting on monday and we discussed about the work of the new students and their program. In this topic, the monday meeting have been moved to wednesday, according to the first day of SJSU students. 


Overall the two main topics this week are the RFI questions and Jacques-Hariel's design on small scale podcar integrating sensors. 

Jacques-Hariel and David (Mapapa) work on the small scale approched by Bill James on design and control system. Currently the principal sensors and actuators we are working to integrate are  :

-Pixycam : Recognize shapes and colors 
-Ultrasonic : This one has already been used on the 1/12th scale podcar to detect any other podcars on the track. 
-Accelerometer : Fixed inside the podcar, it measure the acceleration in 3 principal axis and then allow to determine the position of the podcar in space. 
-Tof (Time of Flight) : Also used to detect obstacles

-Servo : Used to rotate the Pixycam. The podcar will be able to "look around" a corner to check if there is another podcar at the end of it. It will also be able to follow a target which can be usefull to recognize a corner or a swicth area. 
-Motor : Use to operate the driving wheels.

There is the design Jacques-Hariel has been working on :

Front view


On this view we can see the ultrasonic at the bettom, the Pixycam in the middle and the ToF at the top. There is enough space inside for the arduino card and batteries.


Back view

On this back view, we can see an other ultranonic at the top, a Neopixel (Led) and an other ToF. All of them are positioned to avoid any inteference in their signals. The Neopixel serves as an indicator for the Pixycam (of the podcar in behind this one).

Inside view
On this last view, we can see the Pixycam operated by the servo.

Now we have to work on the control system to get all sensors and actuators communicating together.

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 tr...

Fifth and sixth weeks - 07/29- 08/09/2019 Last week (07/29 - 08/04) was a really interesting working time. We had the visite of Bill James from Oklahoma, funder of JPods and he has brought with him some gears. Electronic components, lazercutted parts for the track, a 3D printed podcart and his softweres. Overall, the most important thing was his enthusiam and knowlodge about PRT system and our commun (the whole team and him) desire to see this built. A long this week, Ron, Bill, Ethan, Thomas, Husain and Jacques worked on JPods small scale track to get it operating. We met many issues on the assembly and needed to modify some parts. We figured out together how to resolve that and after some days, we came up with the track which still need some improvement but works fair enough as reference for improvement.  Bill ajusting the track The track  The switching area Beside the work in the design center, we talked and worked on the business aspect of all...

Fourth week 7/22/2019 - 7/27/2019 : (More) Improving Designs On monday meeting at 4pm with Ron, Pr. Furman, Eric, Ethan and Jacques-Hariel we talked about the designs of the last week. We introduced Thomas (Jisup) who is an industrial design major and he talked with Pr. Furman about his participation in the projet and about the work done by the last industrial design majors. We had another meeting at 6h30 with Daniel and he gave some ideas to simplify the switch of the 2 floors bogie (crank rod system) and proposed to make the switch axis smaller to improve the stability. Jacques-Hariel worked on this from tuesday until the and of the week and modified the 2 floor bogie (Bogie model 3). Bogie Model 3 Bogie Model 3.1 On the model 3.1, the switch axis is smaller (on top) and servo (in blue) is rotated to decrease the number of parts. However, this system is kinematiclly not working, we you use a rod from the servo and...
