The mechanical design was done with Onshape as our CAD tool. It is simple to use and allows for collaboration and version control. Many different manufacturing techniques were used such as 3D printing, laser jet cutting, water jet cutting, lathing, and milling.

The chassis was built out of hardboard and reinforced with water-jet cut aluminium bars. This component required the most communication to perfect as every other part of the robot needs to screw into it.

H-Bridge: common questions

How big is the H-Bridge PCB?

The H-Bridge measures 110 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the H-Bridge?

59 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the H-Bridge design files?

From the Luca-Jones/enph-253-pet-rescue repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the H-Bridge design in my own project?

The repository has no license, so all rights stay with Luca-Jones. Use it as a reference, and ask the author before reusing the design.
