I am a member of Aberystwth Robotics club and I've created a car using the 3D designs on Tinkercad.
I'm using this website to show my design I created
This took me 2 weeks to design, and I found some very instersting things out (including the animals in the car!!)
At the front I have an ultrasonic sensor, and at the back I have an arduino which you can see tiny bit of at the back of the car!
I am very pleased with how my vehicle turned out. I would have changed how some of my shapes align with each other. My favourite bit is the penguin and the bee!
