Full Group Meeting (11/9)- Chassis Progress and Purchasing

Summary: We met briefly to discuss work on the chassis and divide the remaining SolidWorks modelling.


We have now confirmed that we can have the chassis laser cut through the MakerSpace. Additionally, we have arranged to purchase:

• 6 of 1227T419 (Optically Clear Cast Acrylic Rectangular Bar, 1/2" Thick, 1" Width x 2' Length, Clear)
• 5 of 8505K82 (Optically Colored Cast Acrylic Sheet, 3/16" Thick, 12" x 24", Black)

For electrical components we ordered:

• 1 Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
• 4 Stepper motor - NEMA-17 size - 200 steps/rev, 12V 350mA
• 1 Parallax Ping Ultrasonic Range Sensor 28015

Prior to the meeting, preliminary work in designing the joints for the chassis was complete. This produced a basic layout for joining the main parts of the chassis together (MM).

 
 
 

For Next Monday:
A fresh set of SolidWorks parts will be created (JK) and then additions/modifications will be made to allow for the mounting of the remainder of the parts.

• Holes in the upper fingers of the side wall to allow for hairpin fasteners (JK).
• Slots in the back plate for wires/ventilation (KT).
• Hole in the front plat to accommodate the ultrasonic sensor (KT).
• Holes in bottom plate to mount gearbox and wheel brackets (KT).
• Accommodations to mount the gyroscope (close to center) and Arduino board (KT).
• Revised Rack and Gear Part files (MM).
• Cup Holder (MM).

Finally, JK will outline the conventions for the assembly tracking document, MM will create a complete parts list, and KT will solder the gyroscopic sensor.
