Dune Buggy is usually four wheels drive off road vehicle, which would not be used on the road.
Now that I got excited on the "dune buggy", and was also inspired by 1998 LEGO®'s Turbo Command 8428/8432 (See picture 6 and 7), I designed my own buggy, "The Bull" Buggy.
"The Bull" Buggy is larger, and more complicate car to build than my two other LEGO cars, R/C Lego Car (or R/C Lego Car Redux) and Wireless Lego Car. It needed bigger or more power (torque) to drive the car. So I decided to use round 24mm. diameter with 9V input power. That made me to design another version of 3D printed motor housing (See details in Step 1.)
This 3D printed motor housing was designed to be used with the Lego's parts, and compatible with Lego Modular System just like my smaller version of the motor housing for 130-type DC motor (See Step 1 of my R/C LEGO Car Redux.)
After I built the first "Bull" Buggy, I realized that when I want to access the Palm Arduino and motor controller PCB, I had to tear apart the rear frame to get to PCBs. So I altered the design by adding the hinges to the rear frame so I can just flip the rear roll cage up instead of tear them apart (picture 2 and 3.)
The "Bull" Buggy's features:
- Shock absorbers.
- The chassis is not all paralleled to ground.
- Can be constructed without shock absorbers as an alternative, so the chassis is all paralleled to ground level. With this alteration, the motor could be mounted using the side holes on the motor housing to and connectors to mount to the LEGO bricks (photo 5, or see Step 11 for details installation)
- Rotatable rear roll cage.
- Switchable steering wheel. (Can be switched between the left side and the right side of the vehicle.)
Lego Bricks or parts are already reusable/recyclable products. And it could be passed on to the next generation just like all the Lego parts do. I would say this is the right way to solve the problem and more "green" than hacking toy R/C Motor housing, like I did earlier with R/C Lego Car and Wireless Lego Car projects.
For the wireless control, I used XBee module as an alternative) for controlling the car wirelessly, similar to my previous cars, R/C Lego Car, Wireless Lego Car, Ford Mustang Arduino Controlled R/C Car. (Picture 8)
