I built a new version of my Race cars series (Race1, Race2) with the logical name Race3. This time I am using the SBrick to control the car which gives its proportional steering control. This is great for driving curves. Race3 features individual suspension, ball bearings and a very low centre of gravity. You can drive it up and down pretty much any rock or mountain. Here is a video of what it can do.
This video shows the smallest remote controlled LEGO Off Road car I have build so far. It features a servo steering, an L motor for driving and full suspension.
It has long been a dream of mine to build a remote controlled LEGO car. LEGO has many Technic cars in their program that use the Power Functions to remote control certain functions, such as opening doors or lifting an arm. Power Functions use infrared light for communication between the sender and the receiver. In the past, LEGO also had remote controlled cars that use radio frequencies, which is much better, since it does not require a line of sight and has a much further reach.
Recently, LEGO released the 4×4 Crawler and it really triggered something inside of me. I ordered the set, but when it arrived I never put it together. I started to build my own cars right away. I looked for inspiration on the internet and found many great off road cars, trial trucks and multi purpose car technology. In particular the work Pawel “Sariel” Kmiec. Check out his book “The Unofficial LEGO Technic Builder’s Guide” or visit his website. LPE Power also has some wonderful instructions on how to build real car technology with LEGO.
