Microcore walker

The Microcore walker is a amazing walker. The circuit of the walker is a Microcore. The Microcore is easy to understand and easy to modify. This walker make big step.
Circuit :
1- 74HCT14
1- 74HCT245
4- 0.47uf capacitors <== This is why it make big step
4- 1 meg resistors
2- PCB boards
1- switch to power my creature
1- switch for the PNC (Process Neutralization Circuit)

Microcore circuit

Here is the Microcore circuit. If you want to modify this circuit you can change the capacitors value (.22) or the resistors (1Meg)
• All capacitors value are 0.22uf Bi-polar
• All resistors are 1 MegW
• Power from 3 Volts to 10 Volts



Put a capacitors from 10 to 20 uf across the power source.
This is for spike remover. I didn't know this trick before, my robot didn't work. I spend two day finding the problem and it was the capacitor that I didn't put.



This is only if you put motors. On my breadboard, the Microcore was working great. When I attach motors to the Microcore it didn't work, the motors didn't turn.
This is the motor drive I use in my my Microcore Walker




Chassis :
2- modify servo motors
2- AA battery holder
1- coat hanger for the leg
2- plastic horn to attach the leg to the servos

Here are some advantage and disavantage and some improvement for this robot.

Avantage :
• The circuit if very easy to understand.
• It make BIG step 9 cm or 3.5 inch.
• Compact design.
• Robust.
• Only need one IC chip for the motor drive. (with servo)
• Climb obstacles.

Disavantage :
• Always need to to press that PNC
• The PCB board take alot of space (Freeform would be good)
• Doesn't back up like is brother the two motor walker
