College students assemble their own 3D printer

At present, the most popular body sense game, if like riding a bike driving "need for Speed", in the video game to achieve fitness purposes, players must be very enjoyable. Yesterday, university exhibition of more than 2000 college students Science and Technology competition works, many creative refreshing.

Riding the "Need for Speed" fitness

"Dynamic cycling" is a lot of people like the exercise program, "Need for Speed" is a number of players keen on the game, if the two combined? Zhu Yi, a sophomore at the College of Electronic Engineering, tried.

Zhu Yi said that the gym's dynamic cycling can only play music, a single function, the exercise process is very boring. "If you let the fitness process be situational and interesting, it will definitely attract more people," he added. ”

He got the idea from the game handle and transformed a bicycle: The handlebar is fitted with an electronic compass to achieve directional control; the hall element is installed on the pedal to realize acceleration and deceleration; the brakes are fitted with sensors to achieve braking and reversing. The whole reform only cost more than 400 yuan. Connect to the computer, you can play on the oversized screen "need for speed."

The press turned the handlebar, the car on the screen turned; After proficiency, still can play out drift.

Wouldn't it be addictive to have such a cool game? Zhu Yi smiled and said: "Ride tired naturally rested!" ”

Assemble the 3D printer yourself

Give your girlfriend a rose? It's too corny. But if it's a 3D-printed rose, isn't it very creative? As long as you assemble a computer, you can assemble a 3D printer.

Communication Engineering College sophomore Yang Xudong from the electronic market to buy hardware, servo motor, master control Board, etc., save a 3D printer. Take ABS plastic strip as raw material, can print out a variety of common items. For example, the door handle, hook, glass, and even for the students to develop the robot printing parts.

"It's very popular now." The word "creators", is the design of their own production, the idea into reality. Because the work is small, it is impossible to mass production. This 3D printer can meet the needs of small batch and personalized production. "A classmate of the scene said, save such a printer only need more than 3,000 yuan, but the printing time is really very long," such as is playing this rose, probably need 7 hours. His introduction stunned the reporter.

New inventions help Mine rescue

In case of mine accident, the search and rescue of underground personnel is difficult. Communication Engineering College junior students Zhang Wei, Wang Gashing, Zhao Nan for personnel identification and downhole positioning, the invention of "mine safety supervision positioning Management System", won the 2013 National College students "Challenge Cup" first prize.

Wang Gashing said that after the accident there are usually two problems, one is trapped number and identity, the second is trapped in the position. Every time the miners go down the well, like clocking in, through the management system to identify the iris or facial features, after the accident can be the quickest to know who is under the well, to eliminate the cover-up or missing casualties figures.

At the same time, each miner's helmet is equipped with RFID (radio frequency identification, a communication technology) equipment, can quickly locate miners trapped underground location, error range of not more than 10 meters, to provide a basis for rescue.

Remote control robot to do housework

A robot at the scene attracted a lot of students to the crowd. The main components of the robot are 3D printing, especially the bionic hand, can be like the hands of each individual fingers to achieve flexible movement.

Xie Wenwen, of the School of Electronic Engineering, said it was a remote somatosensory control service robot, the main function of which is to care for the elderly. Many of the elderly mobility inconvenience, with robot assistants, as long as the camera to make gestures, the robot can imitate the action to do housework. Reporter felt a bit, issued an order, the reporter went to where, the robot to follow, ready to serve. The reporter raised his head to the camera, turned his head, and the robot made the same move.

Xie Wenwen told reporters that the robot can also be remotely controlled through the network. For example, can not go home, network remote control robot in the home work, complete some ordinary housework.
