Copenhagen Wheel to assist the elderly and disabled with a power boost..

The Copenhagen Wheel can now be used in offshoot applications.

Why not we make it perform as a self-powered exoskeleton.

  • Using the same principle we could design a knee brace which would charge under normal walking and give that extra power boost while we climb stairs.
  • It could also be fitted on self-powered wheel chairs and help the propulsion on a steep incline.
  • It could be used to help elderly to getting up from a seated position
  • It could generate temporary power during blackouts
  • Power single person lifts at home
  • Could become a wearable power source to charge lap tops and cell phones and be charged by normal walking
  • Self powered walker for the infirm

All of us need a capacitor start at some time or other 🙂


The Copenhagen Wheel for the Senior Citizen pemmPOD

I recently read about a very neat motorized bike hub from MIT.

The gave rise to some lateral thoughts for outfitting the pemmPOD with this motorized hub. The idea is to have a 3 wheeler version of the pemmPOD for senior citizens and the visually impaired. Lets call this the goldenyearsPOD

This would be perfect for a senior citizen complex like Kingspoint in Tamarac, Florida to use as an example but would have applications all over the country. Florida is sunny throughout the year to warrant the solar panels

Lets look at specifications.

  • Inkjetted Solar panels integrated with a capacitor pack
  • 3 wheels
  • Pedal power
  • Battery assist with capacitors optional
  • MIT motorized hub
  • Air bag chassis
  • guidePOD optional for line following
  • iPOD & iPhone enabled
  • Optional nano ink impregnated battery pack chassis
  • Optional PC
  • Optional monitor
  • Optional media station
  • Optional wi-fi
  • Optional auto navigation
  • Optional castor wheel in front

Lets prototype 🙂

Digital Prototypes – guidePOD & lineguidePOD

The digital prototype of the guidePOD and the lineguidePOD is complete


  • Ultrasonic sensors on sides and front
  • Line following sensors on bottom
  • Flashing LED’s on top to warn speeding vehicles
  • Stereo speakers on top for voice alarms and output from media players
  • Microphone for recording comments
  • Digital interfaces
  • Inputs for media players
  • Docking station for iPODS
  • Mounting for lineguidePOD



The system is for helping the blind and visually impaired travel following a line and avoid obstacles

lineguidePOD for the Blind and Visually Impaired

The line following guide for the Blind or Visually Impaired

Application for the guidePOD

The lineguidePOD is one of the practical applications for the guidePOD.

The system is fabricated from off the shelf components including 80/20 extrusions and a modular standard a standard guidePOD described in an earlier blog.

It can be used around the home, office, library, grocery strore, mall or community where line have been painted or marked to have a more user friendly atmosphere for the blind or visually impaired.

The system will warn the user when  they are straying away from the line or if there is some obstacle like a lamp post.

User Friendly Habitats and Communities for the Blind and Vision Impaired

My wife has Glaucoma. She cannot see very well in one eye. It is possible she may even lose her eye sight over the years. Now, this could be a condition for a certain percentage our aging population in the world. We are talking about making more User Friendly Habitats and Communities for the Blind and Visually Impaired with all the technology we have already established in the world.

User friendliness begins at home. So let us start with our habitats.


We have seen toy robots following a line using sensors. Very simple and inexpensive and technology. Can be made from off the shelf components and even assembled at home. Could be in the form of a self contained module. Users could strap these to part of their body or walking sticks to follow a line painted or taped around the house. Now since we can do it a home, why not take it to office, the grocery store, library, school, music concerts, side walks, parks, malls and communities. I am going to call this module the linePOD

I have talked about the guidePOD in an earlier article. This is a distance sensing module which can be strapped to parts of our body or walking sticks.

Now we could have competitions for schools, colleges and communities to design various phases of this project.

We could use Google Wave to share and collaborate online on various phases of this project including Design, Manufacturing, Distribution and Service.

It is also possible that Apple or others may incorporate this whole module in their iPOD Nano’s.

We could also ask the Bill Gates foundation to fund it as ongoing research on extensions to the concept.

Who knows we could even run the run the project through a virtual non-profit corporation  run purely by volunteers. We are talking about virtual funding with virtual volunteers.

Looks like Chris Bangle with his talk about the Personal Emotional Mobile at Singapore continues to inspire more lateral thinking.

Design Thinking and Blogging has changed my life.

guidePOD – Helping to lead blind or vision impaired people around obstacles.

The guidePOD is a module which can be worn on the arms, legs, chest, waist, head, walking sticks, guide wheels and special purpose mobiles to help lead blind or vision impaired people around obstacles.

The basic components of the guidePOD are as follows

  • Ultrasonic Sensor
  • Micro-controller
  • Power Supply (Battery)
  • Alarming device
  • System Mounting Box slots for mounting bands
  • Arm, leg, waist, head or stick band
  • iPOD docking station is an option 🙂

These are all off the shelf item which we can purchase from hobby electronic stores. Companies like Parallax list all above components in their web site with very good user manuals.

The guidePOD can also be mounted on a 80/20 extrusion fabricated guide wheel which will be christened as the gwPOD. The gwPOD would have the added advantage of sensing steps, curbs, potholes etc. It will also have a built in generator to power lights, batteries etc.

Another commercial application for the guidePOD could be for the pemmPOD as anti collission sensor.

In essence this module could be used in any location where a distance has to be detected between specified bands and and alarm sounded as a warning.

Now on to Digital Prototyping
