Electric Go-Cart Has Arduino Brains

arduino powered go cart

Oh how times have changed. Back in the 30’s the VW Beetle was designed to be cheap, simple and easy for the typical owner to maintain themselves. Nowadays, every aspect of modern cars are controlled by some sort of computer. At least our go-carts are spared from this non-tinkerable electronic nightmare…. well, that’s not completely true anymore. History is repeating itself as [InverseCube] has built an electronic go-cart fully controlled by an Arduino. Did I forget to mention that [InverseCube] is only 15 years old?

The project starts of with an old gas-powered go-cart frame. Once the gas engine was removed and the frame cleaned up and painted, a Hobbywing Xerun 150A brushless electronic speed controller (ESC) and a Savox BSM5065 450Kv motor were mounted in the frame which are responsible for moving the ‘cart down the road. A quantity of three 5-cell lithium polymer batteries wired in parallel provide about 20 volts to the motor which results in a top speed around 30mph. Zipping around at a moderate 15mph will yield about 30 minutes of driving before needing to be recharged. There is a potentiometer mounted to the steering wheel for controlling the go-cart’s speed. The value of the potentiometer is read by an Arduino which in turn sends the appropriate PWM signal to the ESC.

Le-GoKART; a GoKart built entirely from Lego

[Eric Steenstra], from the Netherlands, decided to build a GoKart entirely from LEGO Mindstorm parts. Tested at being able to carry just over 100Kg in weight, a 16 stone man(224 lbs). This GoKart can easily carry a child and propel him along. Eric used 48 stock Mindstorm motors, geared down,  and 16 battery packs to provide a balance between torque and speed.

This vehicle doesn’t expect to win any races in the speed department. From the point of view of being something different this wins hands down. The Karts first test drive was only two weeks ago so drivability and durability are still under development at this stage.  See the video after the break on this monstrous Mindstorms creation.
