[ Electrical Division : Electrical - Mechanical Integration ]
Created by [ Mitchell Hoyt] on May 16, 2020
The Electrical and Mechanical divisions will be running bi weekly remote sessions to plan and document the following topics
- Test Track Infrastructure
- Figuring out how to develop the intersection lights
- What intersection lights we need to purchase
- how are we going to put them at the right height
- How are we going to develop these lights so they are safely being operated, and pose no risks to users
- Cable Management
- Discussing how we are going to route the wires for the radar, how it will fit on the compute rack
- Look into how to better manage the wires for the Novatel
- Blue light wire management

| Hoyt{.confluen |
| ce-userlink |
| .user-mention} - Some updates on the work done in previous term |
| |
| Sensor Interfacing cable management |
| |
| - Wires for Novatel imu unit have been routed from sideways making |
| sure the seat-belts can still be used but the length of wires |
| under the rear right seat has created a sort of bulge making it |
| difficult for person sitting on the rear side to rest his/her |
| feet on that cover. |
| - There's a VLP 32 (LIDAR) control box on the roof of bolt needs a |
| 3d printed or some kind of protection in case weather decides to |
| change which can be issue now that the challenge has been |
| extended to fall season |
| - The three cameras mount was almost done thanks to Chad |
| Kirton{ |
| .confluence-userlink |
| .user-mention} but still we have to finish mounting of new covers |
| for cameras which won't go in as the diameter of cover is |
| smaller than the diameter of the lens. |
| - The third camera has fish-eye lens mounted on it not sure why but |
| maybe (for performing disparity calculation which is an effective |
| way to describe a 3D Cartesian space) which can help the |
| perception team but during our testing we found that the current |
| place of third camera mount doesn't really help perception team |
| and needs to be somewhere just below the VLP-32 Anita |
| Hu{.conflue |
| nce-userlink |
| .user-mention} can update you more on this. |
| - The monitors on the front and rear side both have long enough |
| cables for operation but the monitor stand on the rear side keeps |
| falling which needs to be more stable but it's a minor issue. |
| - The CAN controller near the driver's seat needs to be at a place |
| which does not affect driver in any driving scenario. |
| - SI team has changed switch from 1g to 10g, so we can unplug the |
| other one if there's no use Rohit |
| Kochhar{ |
| .confluence-userlink |
| .user-mention} can help you with this. |
| - We have reverted back to 1-1 port PoEs (Power Over Ethernet |
| injectors) from 4-4 port PoEs for cameras due to unknown hardware |
| issues in 4-4 port PoEs. Rohit |
| Kochhar{ |
| .confluence-userlink |
| .user-mention} take help from power systems for resolving this |
| issue, but this resolution has led to increase in number of power |
| adapters required for powering these PoEs, hence we need to use |
| both power bars( one on left and other one on right). |
| - Last but not least we need to have fixed positions for every |
| component on compute rack, because it creates more problems for |
| Mechanical team to adapt with these changes , so I would suggest |
| that we follow Chad |
| Kirton{ |
| .confluence-userlink |
| .user-mention} 's distribution diagram for this purpose (CAD |
| model), and make necessary changes. |
