RC car transforms into RC robot

Transformer

After nearly 30 years since the first episode of Transformers aired, someone has finally done it. A company named Brave Robotics out of Japan has created a true transformer robot that is half remote control car and half remote control bipedal robot.

According to the Brave Robotics’ site, this creation is the result of more than 10 years. In 2002, the first version of the Transform Robot was completed – a relatively simple affair that transformed but couldn’t walk or drive. Over the last 10 years, the prototypes have seen incremental improvement that included a drive system for the wheels, a steering mechanism, and even the ability to move its’ arms and shoot plastic darts.

Surprisingly, you can actually buy one of Brave Robotics’ transforming robots for ¥1,980,000 JPY, or about $24,000 USD. A little pricy but we’re sure we’ll see a few more transforming robots in the future.

Check out a few more videos of the Brave Robotics transform robot after the break.

An introduction to vector displays

clock

Unlike the CRTs found in big old televisions, vector displays are a bit of a historical oddity. Instead of sweeping an electron beam across the screen from left to right and top to bottom, a vector display draws lines between two points on a screen. Once used in arcade games such as AsteroidsTempest, and old FAA displays, vector monitors have fallen out of favor due to either the complexity or difficulty in acquiring the needed CRT. The folks over at NYC Resistor put up a great tutorial for getting a vector display up and running, and even managed to put a clock on an oscilloscope.

The key component of getting a vector display to work is the digital to analog converter. This DAC takes voltages from eight pins on a Teensy 2.0 dev board and converts them to a voltage anywhere in between 0 and 5 Volts. After connecting the output of this DAC to an input on an oscilloscope, the microcontroller can draw a line between any two points on an axis.

In the video after the break, you can see two of these DACs connected to an oscilloscope displaying a clock. It’s a very cool piece of work, and something that finally gives a purpose to the ancient CRT oscilloscope you might have lying around.
