Let's Make Robots!

RTW-II @ Wolferion Mechatronics

Navigates autonomously, finds and identifies yellow bag, picks it up and brings back to owner.



Old version base:


Current version:

Electronics are inside yellow box, which will not be used in final version.
(Current weight ~10kg (1x 12V 5Ah inside box) )

"Hold" mechanism.

Wooden boards are used for reference at the moment.



Here is scheme of electronics. It is ~60% complete.



Eyes of the robot:



No images of electronics at the moment.
Sorry for no videos, I'll try to upload soon.


More information coming soon. Please feel free to comment!

the tracs are bike chains?

 

is some kind of plastic tube split in half for traction?

 

CLEVER IDEA! Great job...

Also It had too much sideways traction when the robot was rotating around so I thounght about rounding "hard" edges.

Yes, it's bike chain with half-split plastic tubes bolted on it.
However this concept has one drawback - small roller wheels tend to "fall" into gaps between two tubes and as result it is vibrating when riding on hard surface, such as concrete!

However I came up with solution:



Im going to attach aluminum plates to round side of tubes in order to minimize gap size by 91%, then wheels will move smoothly!

Basic concept was done before:
