However, I have used it to create some relative complicated designs very quickly with with little time invested in learning its use.įreeCAD, although I have not used it and only watched tutorials seems to be somewhat in the middle. It is more intuitive to use but lacks some of the more advanced features. TinkerCAD is at the opposite end of the scale. If you are thinking of potentially doing CAD design professionally this could be a good choice. However, the learning curve is quite steep. However, they all have unique interfaces and typically the more complexity the software can handle the steeper the learning curve.įusion 360 is free and is very powerful. There are a lot of crossover aspects of CAD software that once learned can be transferred between the various packages. You may want to look at the decision as to which software to start with in terms of the quantity and frequency you plan to design, and the envisioned complexity of your designs. Here are a couple of pictures and a video. This little tip saved me hours of programming frustration. By doing this the X and Y outputs from the joystick line up with the left and right motors. That tip was just to rotate the joystick 45 degrees. In research for the project I picked up a tip that made the software that reads the joystick and creates the control values for the motors. How much more is unknown as I couldn't see the tank any more when it was commanded to return. The tank can be controlled from more than 300 feet. The radio transmission distance was also surprising for such inexpensive devices. The track flexibility was a pleasant surprise as was the durability.

The unique items may be the tracks that are a one-piece print using TPU plastic. The motors have an a metal 90:1 rear train that gives it good speed when powered from 2 16850 LI-ion batteries. The tank dimensions are 250mmL X 150mmW X 100mmH. The tank was designed using TurboCAD software and components were printed on Artillery X1 Sidewinder using PLA and TPU filament. The project included 56 3D printed components, 34 screws and nuts, 2 Arduino Nanos, an H-bridge driver, a 443Mhz transmitter and receiver. A recently completed project for my grandson was a fun project that brought together 3D design and printing with Arduino micro controllers and radio control to produce a easily controlled tank.
