What is WaterBotics?• LEGOTM MINDSTORMS robotics in underwater

environment• Approximately 20-hour curriculum aimed at middle and high

school classes as well as summer camps and after-school activities

• Primarily funded by NSF Innovative Technology Experiences for Students and Teachers (ITEST) Program– Award #0929674: Build IT Underwater Robotics Scale-Up for STEM

Learning and Workforce Development (BISU)

Page 3: WaterBotics

Partners• Stevens Institute of Technology

– Center for Innovation in Engineering and Science Education (CIESE)– Development of curriculum– Primary training and support

• League for Innovation in the Community College– Selection and support of community college partners to target formal educational

environments (i.e. schools)– Year one selection: Sinclair Community College

• National Girls Collaborative Project (NGCP)– Selection and support of informal education programs, especially those aiming to engage

girls– Year one selection: Texas Girls Collaborative Project

• International Technology and Engineering Education Association (ITEEA)– Development and dissemination of a hybrid professional development program built around

WaterBotics curriculum

Page 4: WaterBotics

Why Underwater Robotics?

• Presents unique, complex design challenges (e.g., buoyancy, control in 3-D)

• Exposure to concepts like propulsion, drag, buoyancy and stability, gearing, torque, speed, and thrust

• Awareness of careers that involve the types of skills developed in the project

Page 5: WaterBotics

Why LEGOs?

• Familiarity (in some cases)• Ease of use and durability• Variety of pieces• Rapid prototyping, testing, redesign

– “Tweak friendly”• Fewer components required to create start-

up kit

Page 6: WaterBotics

Project Challenge

Using LEGO and related components, create an underwater ROV (remotely operated vehicle) that will be able to

pick up weighted wiffle balls and deposit them in a bin.

Page 7: WaterBotics

Task 1 – Straight Line Challenge

• Use a single motor to build a vehicle that can travel the diameter of the pool on the surface as quickly as possible.

• Optimize gearing to achieve best propeller speed.

Page 8: WaterBotics

Task 2 – Figure Eight Challenge

• Use a second motor to enable steering.

• Maneuver on surface to complete a slalom course around two buoys in shortest time.

Page 9: WaterBotics

Task 3 – Vertical Challenge

• Use a third motor and other materials to control the vehicle's buoyancy in order to descend and rise vertically in water.

• Maneuver through the same slalom course as in the previous challenge, except this time underwater.

Page 10: WaterBotics

Task 4 – Final Challenge

• Produce a vehicle which can retrieve the greatest number of objects from the bottom of the pool within a specified period.

• Objects must be deposited in bins at various depths in the water to score points.

• A fourth motor may be used to come up with some way to grab and release the balls.

Educator Support• Hub site staff

– Visits to schools– Email and phone availability– Optional follow-up professional development

• Website– Course management– Interactive FAQs– Curriculum updates

• Optional Webcasts

Page 15: WaterBotics

Research Questions – Study 1

Professional Development Fidelity• Is the program delivered with equal fidelity in different

environments?• If not, what are the differences between trainers and also

between formal and informal teachers/staff and what accounts for them?

• If the curriculum is altered, what is altered and why?• Are there critical components of either the PD or the

curriculum without which the intended outcomes cannot be achieved?

Page 16: WaterBotics

Research Questions – Study 2

Student Impact• Is the curriculum as effective in a wider range of settings

as in the setting in which it was originally tested?• Are student outcomes similar regardless of the teaching

environment (formal vs. informal)?• If they differ, what are the differences and what accounts

for them?

Page 17: WaterBotics

Research Questions – Study 3

Scale-Up and Sustainability• To what extent does/did each hub partner implement the

Build IT model?• What is the correlation between the levels of success of

hub partners in meeting the project’s overarching goal and their fidelity to the BISU model?

• What adaptations, adoptions, partnerships, and/or collaborations resulted from implementation of the project?

Page 18: WaterBotics

Research Questions – Study 3

Scale-Up and Sustainability (cont.)• To what extent did hub sites become self-sustaining by

their fourth year in the project?• How and to what extent did hubs develop a local funding

base? • What capacity-building activities occurred to enable

project sustainability?• To what extent did hub sites scale up or expand the Build

IT program?

Management & Staffing

Assets (the kits):Managed by a system involving inventory checklistmade “simple”. Tested out in the summer camp andnow in the classrooms and… so far… it works.

Staff (the people):Currently (2) full-time faculty from differentdepartments are funded under the grant to work withthis project. The student aide for EngineeringTechnology is being pulled for this project and volunteers, mostly those in the EngineeringTechnology program, are assisting with the logisticsof the program.

Page 25: WaterBotics

Successes:• (1) school done with students, parents, teacher, and school happy. • (2) schools in process, balance in the works• Contacted by (3) schools contacted us to be involved, because they heard

about work to date!

Challenges:• Off campus concerns (ex.: 7 motors failed at one school)• Scheduling kits out to schools on their preferred schedule• On campus concerns (ex.: asset management, scheduling)

Upcoming & Long Term

Page 26: WaterBotics

Upcoming & Long Term

Upcoming include:• Kit distribution to remaining (8) schools• Summer 2012 Summer Teacher Training Institute (focused on middle school

faculty)• Summer 2012 Summer WaterBotics Camp (for youth in 7th and 8th grade)• Have fun working with the teachers and youth!

Long term (already in WIP) include:• Work with area businesses on support for long term sustainability of program• Promoting the use of kits by current teachers for summer programs to increase

interest in STEM and possibly use as a funding vehicle to help supplement the purchase of their own kit, keeping the program going after this first year

• Planning out how the current round of teachers can mentor the next round of teachers, thereby seeding best practices

to set them up for 2011-2012 school year

• Stay in contact with all the teachers to provide support

Page 33: WaterBotics

Summer Camp in W.V.• http://www.youtube.com/watch?v=h3P

Page 34: WaterBotics

Convenience for teachers

• Material provided• Curriculum ready to go• Loads of support material• Technical support from Hub site

Page 35: WaterBotics

Challenges facing teachers

• Slotting time in a busy school year• 50 min. sessions are difficult• Space to keep a 12 ft. diameter pool

Page 36: WaterBotics

What’s next• Summer Camp 2012

– 20 students• Teachers Institute 2012

– Recruit 20 teachers

Page 37: WaterBotics

What’s next• Continue to solicit sponsors until the

program is fully funded• Recruit another person at Sinclair into

WaterBotics• Investigate Home School sector of

education

Page 38: WaterBotics

Successes• Vectren has agreed to be one of our

sponsors

Page 39: WaterBotics

Successes

• FUN

Page 40: WaterBotics

Successes

Page 41: WaterBotics

Challenges for Sinclair• Recruiting teachers is getting more difficult

– Like other States, Ohio is cutting back on school funding

– Ohio is changing it states teachers retirement plan• A large number of senior teachers are leaving now

before the plan changes.

Page 42: WaterBotics

Challenges for Sinclair• Finding new schools

– Recruit from schools farther away

• Finding and maintaining sponsorship to fund the project into the future
