Build Begins

Let the build begin.

The first task is to complete the 1:10 scale car build. My build is based of the openRC truggy. While all of the parts will be 3d printed, the required electronics will be sourced online. At a high level the electronic components that will need to be sourced are a DC motor, a servo (for direction control), lipo battery and an electronic speed controller (control the speed of the motor and hence the car).

The motor and servo will be sourced from hobbyking.com. For esc (electronic speed control) will be using a open source esc called vesc (vedder electronic speed controller). Vesc hardware and software stack is open sourced. Vesc original purpose was to attach and control electric motor to skate boards my purpose will be to drive a 1:10 scale car.

My project will finally link to MIT autonomous RC car. Once the 3d car is built, I hope to set it up with a nvidia jetson tx2 dev board and some sensors and let the car drive a miniature circuit. The project will mimic both the MIT Racecar and Nvidia Racecar /J, taking the best of both. That's a bold, crazy plan, I know will have to make it work.

Here is are time lapsed videos of the car parts being printed and put together

Finally car base all printed and joined together. Feeling excited.



New Project - New Resolution - New Hope

As we year 2017 comes to an en, I have made a resolution for the coming year 2018. The preparation have started right now. Plan to build a RC car fully 3d printed using my newly setup Prusa i3 (open source) hardware and software. The intent is to combine my hobbies and liking and build a fun project.

The project will include robotics, 3d printing, machine learning, deep learning and hopefully the result should be a autonomous self driving 1:10 scale model car. It seems like a bold crazy move but will involve loads of learning experimentation, some cash burn, sleepless nights but I hope the end result will be totally worth it all.

While the entire project will rely on the opensource software stack to gets things up and running.

Firstly my Prusa i3, I have sourced all my printed parts from Prusa research, so in a way I am contributing to there efforts in open sourcing the hardware and software stack. Kudos to Joseph Prusa for his efforts in making the i3 the best entry level 3d printer for hobbyists and like.
