[PRJ] R/C vehicle

This will be our project: a Remote Controlled vehicle (car, van, tractor, truck, quad, dumper....)

Its construction will involve applying several technical skills (mechanics, electricity, wooden handicrafts...)

Useful web pages:

• LOGKIT 1845 (to help you with your freehand sketch, page 5)
• Paco Ruiz's Blog (images, videos & construction)

Please note, here are some important details (to simplify, they can only turn in one direction when moving backwards):

Our DC motor with reduction gearbox and our available tyre sizes force us to install it into the vehicle chassis in this position (unless you want to use bigger tyres):

Approx. dimensions of this mechanical part are:

[width x height x depth] (as seen in above photos)

34 x 55 x 33 mm (without external gears)

55 x 55 x 44 mm (with external gears & mounting tabs)
150 mm axle track (as shown in picture below)
