Team Update: 02/10/2021

February 10, 2021


Mechanical:

  • Axles (material: delrin) were created using a lathe by Carlos


  • The 3D printed housing was created by Kristian to assess the scale

  • We are currently working on solutions to fabricating the bogie as the 3d printer we have moung the team are too small 

  • We have a contact for a large enough print bed in the makerspace, and are currently working on getting a finalized STL file to submit 


  • Lengthen chassis design, current bogie is ⅓ - ¼ of core’s team length

  • Create port on the rear of the housing/chassis for charging 


Electrical:

  • 3.3V and 5V original lines where found to be insufficient, getting new voltage regulator from Droking for the sensors and Microcontrollers 

  • Microcontroller for Switch Arm deemed sufficient, design on 3rd iteration due to incorrect female housing pins and circuit protection

  • New Battery packs are coming in, new motor coming in

  • Need to get hands on second motor and switch arm motor, transient response is worse than originally expected, need to prototype next week with Switch arms motor and two maytech motors

  • The ESP 32 module was connected to the internet, developed a connection with the influxDB.

  • Made a folder on Grafana and developed a dashboard to store and pull data.

  • Made progress on understanding how to set up an MQTT server and communicate with it on the same network using a VPN. 

  • Design for two batteries instead of one


LIDAR

  • Integrating velodyne ros package

  • Working on extracting 2d data for use with hector slam
