Alf 1 - The complex way
This was the first try - and "rests in peace" by now !
What do you do if you want to build a robot - independent on ground surface ?
Yes exactly give him a chain drive !
Thats what i thought and built one.. or tryed to.
Chain drives are complex - i know by now.
The motors are 2 gear-motors running with 12V DC.
Two encoders were used for controlling left-right wheel speed (as in Bugrug2 later)
The bevel gear wheels exposed as the week point in the system later.
The "brain" of it all is a Z80 CPU card with this components installed:
- Ultrasonic distance unit
- Electronic Compass
- Radio Datalink
- Linear Motor driver unit with wheel encoders
- 8 Bumpers
- 4x20 Display unit with 6 Timers and a lot of IO Stuff.
- Voltage supply unit for 15, 12, 5 V DC and recharge mechanism.
The mechanics were built on my EMCO lathe.
The toothed beld i bought in a special rubber shop nearby.
