I do not go in to all of the details such as “download the Arduino IDE…” That would require a book. I use the 0.1” Molex C-Grid system for wire interconnections and terminations. Digi-Key is my go-to source for specialized parts such as Molex C-Grid connectors. Admittedly, you have to wait several weeks for delivery (my average is 3 to 4 weeks). I also purchase generic integrated circuits from China such as the MCP6001 op amps, TCST1103 photo interrupter, DRV8833 dual motor control and SS34 Schottky diodes. The smallest resistors and capacitors are 0805 size so hand soldering is straightforward. I buy nearly all of my components through AliExpress. Although I have supplied files in GBR, DXF and STL format, I would encourage you to generate these files directly from Fusion or DipTrace – I have had disturbing results with. Schematics and PWB layouts are supplied as DipTrace files.
DipTrace can export Eagle files if desired. DipTrace is free for non-commercial use to create one- or two-layer boards with a maximum of 500 pads. I use DipTrace for schematic capture and PWB layout. Inkscape is pretty good at sorting out these file incompatibilities. Some laser cutters are incapable of importing.
The basic requirements for the CAD are to be able to export. This is a free (non-commercial) Autodesk 3D CAD system. The mechanical aspect of the project is designed using Fusion 360. Additionally, I had some larger robotic projects in mind that would benefit from the higher intelligence that a Raspberry Pi would bring. Consolidating all communications over Wi-Fi would be a serious improvement. They all work, but it was always a hassle getting all of the components set up and working properly. I have used RF and Bluetooth links with 900 MHz / 2.4 GHz / 5.8 GHz data link and video transmitters and receivers. But all of my previous robotic projects have been plagued by communications hassles. Over the years I have built lots of run-around-the-floor robots with varying degrees of autonomy. Modular hardware to support larger platforms.Pi compatible power supply with pushbutton ON/OFF.Software differential motive power and steering.Supports DC motors and brushless motors.Raspberry Pi for higher level processing.Wi-Fi connected supervisory command and control.Tasha Yar, Star trek…) is intended as a modular hardware and software development platform for robotics projects. I would like to introduce YAAR – Yet Another Arduino Robot.
