And now my second bot

Killer-Wolf

Learning from my many errors with Alpha-Wolf I made a key change to my approach in building the robot, which was not to use glue to attach the parts. And my attempt to fix Alpha-Wolf gave me the idea to flatten the top of the robot to make it more stream lined.

As Killer-Wolf is a rebuild of Alpha-Wolf I decided that the wheels should be further back to avoid the robot being off balance by the weight placement and that the base and back panel be a single piece to add strength to the robot. The picture above also includes the first version of the new flipper which was replaced.

I then added the side panels to the frame which would also add to the structure strength. Unlike Alpha-Wolf I used bolts instead of glue to fix my makeshift brackets in place.

I got rid of the flipper panel and mounted the motors to the base using polou motor brackets and a custom made plate to mount the brackets onto, that resolved the ground clearance.

I made the new flipper panel one solid piece that also doubles as the top panel of the robot.

A picture of the electronics after they was put inside I cut down on wire by changing the transmitter and receiver from the Blue Planet T5 to the Spektrum DX5e as that didn't need a separate mixer cable. I also made a mounting point for the servo motor that can be removed if I need to take out the battery or receiver. This picture, also shows the first version of the roll bars on the sides and on the back. Which turn out to be ineffective and pushed Killer-Wolf over the size limit slightly.

Here I had started to work on new Roll bars taking some inspiration from robots like Behemoth that use curved roll bars shaped like upside down tear drops to control the direction the robot could roll. The second picture shows a early go at fixing a elastic band to the underside of the flipper and hooking it to the base to help pull the flipper back down as in tests the flipper sometimes got stuck open.

And with Killer-Wolf ready I added a it's name and logo onto the flipper to complete the look.

Pending a final weight check Killer-Wolf is ready to make its fighting debut.

But until then I got to build two more ant weights for my Brother and Sister who have become Robot fighting fans themselves.
