2. Build a bicore - Replace the photodiodes with 1 (one) 3M resistor.
3. Build a motor driver - The H-Bridge Should work fine
4. Hook up the motor driver to the bicore - A simple trick
5. Hook up modified servo motors to the motor driver - How to mount it.
6. Putting a reverser on the walker - How to build and mount it
7. Attach legs to the walker - Whatever
8. Putting it all together - Finishing the walker and trouble shooting
