BEAM Walker

BEAM Walker (updated)

After several attempts with "own" electronics, I decided to make this walker a BEAMER.

With some experimenting with the resistors I've found that the values mentioned in the circuit work OK. It really works fine and backups for several seconds when bumping into something with one of its feelers. The backup time can be changed by using other values for the 3,3 uF capacitor or the resistor of 1 Mohm beside it.

Use H bridges where M is mentioned. When going backward there is a cricket sound.
With these walkers the leg layout is very important. If one leg is longer than the other, it looks like the walker is limping. Don't be disappointed when it doesn't walk fine the first time. Just experiment with the legs layout.

Power is coming from 4 rechargeable batteries with 750 mAh. You just have to see one of these guys walking and reversing; Really cool!

Maybe one day I'm able to make some videos!
