Importance of HandsOn for Creativity

Importance of Hands-On for Creativity

• The meaning of Creativity in Chinese is
  create (?) and make (?). Without making one
  can not create anything.
• The goal of the courses with hands-on exercises
  at National Central University at Taiwan is to
  enhance the design ability of the students.

2
Hands-On Course Introduction to Machine and
Instrument

• This course is designed for Freshmen.
• Objectives of this course is to introduce the
  historical development as well as the working
  principles of machines and instruments.
• Besides the lecture, there are also some hands-on
  exercises in class. Some of topics in the last
  year are
• Steam boot
• Electrical Car

3
Making of Steam Boat

• Through making the boat with the simplest steam
  engine, students can learn the fundamental
  working principle of powered machine.
• Materials are given to students to build the
  engine
• 1/8 inch soft copper tubing
• candleholder
• Students must search other suitable materials for
  boat body, e.g. soft drink can, carton etc.

4
Making of Electric Car

• Through making an electric car, students are
  encouraged to understand the basic structure and
  knowledge on automobile.
• Basic Configurations
• One brushless DC motors, 350 W, 24V (for E-Bike)
• Speed controller integrated within motor
• Wheel arrangement two front wheels for steering
  one rear powered wheel
• Frames of car body 40x40 aluminum-rack
• Energy two Pb battery, 12V, 7 Ah

Hands-On Course Mechanism

• Problems of students learning mechanism in
  Taiwan
• Content of the course is too abstract to
  associate the fundamental kinematic principles
  with real mechanisms.
• Students have difficulties in selecting and
  applying suitable types of mechanism to the
  specific problems after learning this course.
• To encourage the students from the e-generation
  by learning the abstract contents mechanism
  course, we introduce therefore an after-class
  activity through using Fischertechnik as an aid
  for students.

8
Why Using Fischertechnik

• Compact design of mechanism components
• Varity of components that are also used in
  industries, e.g. Flip-Flop controller,
  pneumatics, sensors
• Less effort on development of electric control
  hardware/software, so that concentration on
  contents of mechantronic mechanisms possible.
• Possibilities for further projects on industrial
  simulation with models using Fischertechnik
  modules.

Modules Used in the Exercise

• We dont use the kits offered directly from the
  company, instead we select the necessary parts
  that are suitable for the objectives of the
  course.

11
Modules Used in the Exercise

• Base Components Building blocks, Shafts, Lever
  etc.
• Connecting Components
• Transmission Components Gears, Cam, Pulley,
  Differential (Gearbox)
• Actuators Motor (including also gear reducer),
  Pneumatic cylinder
• Sensors Photo transistor, Reed contact, NTC
  transistor, Limit switch
• Controllers Control card, Flip-Flop controller,
  Magnetic control valve, Electric switch,
  Pneumatic switch
• Software LLWin

Importance of Contest

• A contest can
• motivate the students,
• impart a good sense of reality,
• train to work in simulated but realistic
  industry-like settings of limited resources, time
  pressure, and high competitiveness, and
• teach the importance of co-operation and teamwork.

17
Basic Concept of Contest Applied in Courses

• Contest is a special learning model, in which we
  can
• offer another teaching model, different as in
  classroom, through competition,
• motivate the students to face the problems and to
  solve the problems through activities.
• We divide the contests in our program into four
  levels
• interest,
• concept,
• skill,
• integral.

Creative Mechanism Contest

• A contest using Fischertechnik-modules will be
  held before end of semester. Each student by the
  exercise must participate this contest.
• The theme and rule of the contest will be
  determined by students themselves.
• Topics of the contests for the past three years
• 2001 Castle Attacking
• 2002 Obstacle Car-Race
• 2003 Walking Machine
• 2004 Soccer Robot

Concept of DIY-Lab.

• The DIY-Lab. is based on the concept that the
  students can realize their ideas in a space, that
  is different as the classroom, and in which
  either hardware (hand tools, machine tools etc.)
  or software (handbooks, blackboard for disscusion
  etc.) is avialable.
• Our DIY-Lab. can offer
• Platform for realization of mechanism ideas
• Manufacturing of the machine parts,
• Assembly of final products
• Inspection and testing
• Discussion

26
Equipments in DIY-Lab.

• Machine Tools and Hand Tools
• 2x Milling Machines CNC and Manual
• 2x Lathes CNC and Manual
• Sawing Machine
• Hand Tools (Cabinet set)
• Handy electric tools (drill, grinder, screw
  driver etc.)
• Instruments
• Surface Roughness Instruments
• Granite surface plate and accessories
• Gage blocks
• Micro meters and calipers
• Dial gages
• Oscilloscope
