Key Features

A project log for Skeliwedge Mk4

This is my new iteration of Skeliwedge, my 150g antweight Wedge bot

Following the redesign work and also making changes to the wheel design, I moved forward to designing the key fighting features of the robot, i.e, the wedge and protection parts.

I wanted to utilize the slot-in style mechanism I used for my previous version of Skeliwedge. Therefore I made a big hole in center section both on the front and backside of the robot. This involves adding a bit more of wall for the wedge attachment's guide and adding the top part of the guide to the top plate.

Next I thought of adding more free moving forklets just to test their viability. Thus I added small nubs on the front bottom and back top sides of the chassis where I will attach small forklets for ground game.

I utilized the side holes and the motor-wheel placement to create simple side armor that will protect my wheels from spinners. I need to further polish and design and build final versions of them in PETG.

As for the wedges themselves, I have just created a template design for them. I need to spend a few hours to finish building and printing the final version in PETG.

And experimental feature I have added to my current design is shock absorption by the robot using springs mounted between the chassis and the wedge attachments. This is something I thought when trying to come-up with ideas on how to survive impacts from spinner. I feel that this gamble has a good chance to pay against most spinners(overhead saws are still a pain). I have added cylindrical cavities to set the springs.
