Introduction: Step 1: Materials
Begin by gathering all the materials and draw the shapes of the pieces on the foam core.
Materials/Tools: Sheet of foam core, 10 popsicle sticks, Set of wheels, 1 battery pack, 1 input, 1 remote controller, Hot glue, Sautering machine, Any small piece of metal that will fit onto the flipper (optional), 10 batteries for the controller/battery pack, 2 continuous servos, 1 regular servo.
Once you have gotten everything from the materials list, lay them out and get ready to start step 2
Step 1: Step 2: Body and Design
Start off by cutting out the base of your foam core robot. Draw it with a pencil for more accurate lines. Ther should be 6 pieces you cut out with the foam core. The flipper, the base, 2 sides, the back, and the roof. What my partner joe and I did was add popsicle sticks on the sides and interior for maximum strength and protection. But before we started gluing everything we cut everything out and put the popsicle stick on them with the hot glue.
Step 2: Step 3: Body Construction
For the body construction view the picture for an idea and more help. First, we glued the battery pack down near the back middle on the base piece of foam core. Behind the battery pack, we added the input which is where the wheels. And the motor will be plugged into. Next, We will be gluing the walls down. After that, we will need to cut out part of the walls for the wheel motors that will be glued down in the front of the base. After the arches are made in the walls you can glue the motor facing out so the wires are inside the robot and you can plug them into the output on both sides of the base of course. Next glue the back wall behind the input just like walls on the sides. Do not glue the roof yet because we are not done.
Step 3: Step 4: Electronic Wiring
The wiring for this robot is very simple. First, plug the wheels wires into the input in the 1st and 2nd holes. Next, plug the weapon wire into the input into the 3rd hole. Make sure the black wires are all the same way.
Step 4: Step 5: Electronics Placement
For the electronics placement it's important to make your battery pack accessible, so we made the top of chassi to have holes in it so we could change the batteries. Also your servo motors need to be close to the location where you want your wheels and weapon so you can wire them. One more important thing is to make sure that your wires are safe when you are battling and they won't get slashed or cut.
Step 5: Step 6: Wheel Mounting
For wheel mounting you want to make sure you have continuous servo motors to spin your wheels. Also we had both our servos placed near the back of the robot so that we could mount the wheels as far back as possible to make our robot be as low to the floor as possible, so that ay the flipper is more effective. The wheels attach to the servos with little screws so it is really easy to mount your wheels.
Step 6: Step 7: Remote Control
For our remote control we used and r.c car controller. It was previously connected to our servos so the servos knew what to do when we pressed forward, backward, left, or right. Also if you turn on your controller and the servos are running by themselves our controller allowed us to calibrate the sensitivity of the servos themselves.
Step 7: Step 8: Drive
So after you have put in all this work it's time to have fun and drive your bot and see what kind of damage it can do in the ring so here is a quick video to see what your bot may look like:
