This week, I looked more into the induction charging.
Currently, the implementing induction charging could prove to be a challenge
since LiPo batteries, such as the one
that will power the motor, require special chargers. I have found some of these
LiPo battery chargers, but they sacrifice either voltage or current, making
them unsuitable for charging a 7.4 LiPo battery, the battery used last year.
More discussion must be held with my teammate before reaching a decision on the
motor.
This week, while David worked on the Raspberry Pi and the Arduino code, Patrick completed the CAD (computer-aided-design) models. We had to create 3D solid modeling of two parts: the induction charging hub to hold the induction transmitter coil and the pod car door to hold the induction receiver coil. Over the weeks, the CAD models underwent several revisions. The induction hub saw two revisions, with the third design being the final version. Because the 3D printer available to us in the shop, the Prusa Mark3 i2, had a bed length of 10 inches, we had to restrict the length of the charging hub to a safe 9.5 inches. Version 1 simply entailed us placing the hub on the side of the bracket and then screwing it into place on the bracket’s side via the two holes at the top: For version 2, in addition to placing the hub on the side of the bracket and then screwing it into place on the bracket’s side via the two holes at the top, the bracket would wrap around the two bracket...
