VEX Tower Takeover Prototype 1.0 :
VEX 2019-20 Games Tower Takeover-
Since, I am a member of the Burnsview Robotics Club, I will be playing this year's VEX Game which is called Tower Takeover. This Game is played on a 12' by 12' field which is in square shape. This Game is played between 2 allegiances and each of these allegiances consist of 2 robots. The total duration of the game is for 2 minutes which can be broken down in 15 seconds of autonomous period at the start of the match, during this period the robot operates on its without being controlled by a driver. And the reminder time is 1:45 minutes which is is regular driver controlled period and the driver of the robot operates the robot. The Objective of this is to stack or place more cubes in form of towers or scoring cubes in goals and obtain higher points than the opposition to win the game. To add more detail, There are total 66 cubes and out of 66 there are 22 cubes of each color, 22 orange, 22 green, 22 purple & there are 7 towers in which you have to place cubes. To win the match ones strategy can be to have a robot which stack or place bunch of bunch of cubes and the other robot which defend and break the stacks of the other alliance.
New Robot & Strategy -
|
My strategy and thinking for this robot is kind of unique in way. This because my robot that i am building is both different and similar from the robots. So, I call my robot a Plain Claw-stacker, It is called Plain Claw-stacker because it is just like a Reverse Stacker but instead it uses a Claw to load the block on its load plate and it has intakes on the other end to unload and this system can also be called the feed and unload system since it feeds from one ;To begin with the components of this robot, The first Component on this robot is what I call the Base. The Base is basically the drive-base of this robot and our drive-base is made up of 4 omni wheels which we are using because they are amazing for turns and for speed too, 4 C-30s for the wheels and 2 C 25s for the middle and also there is aluminum bar at the back of the robot which is a 15 hole bar and holds the brain of the robot and the battery. The Second component is called the stacker gears and this contains all the gears involved in operating this robot and a intake that compresses the cubes the pulls it in. Currently this plan is a subject to change.

Drivetrain
Our drivetrain for the traybot is a H type wheelbase that looks identical to the Letter H. It consists of 2 C35 channels that hold down the wheels, to add on the wheels we are using are omni wheels the are 4 in total we are not using any of the gear since we are not building a geartrain. Each wheels has a shaft color in it and is connected different motors. Then it has 2 C30 In the middle to support the wheelbase. Lot of thinking and engineering went into this drivetrain. To show evidence you can see below we had made sketches for this design. This wheelbase also has the gearbox in it that lifts the tray. These sketches we really handy since we could refer to them. Then you can see our drivetrain time to time how it came out and it was really sturdy. and was well constructed. this drive needs to be sturdy since it holds the robot on it and the rest of robot.

Our Drivebase time to time
Current Progress and Future Work -
.Currently, I am working on the Wheelbase of the robot. I completed with half of the wheel and is close to be finished but after the wheelbase i would start working on the arm & the stack tray of this robot,after completing the arm we would make the intakes the back arms of this robot. This wheel base is a H type wheelbase. After the wheelbase is fully completed we would be completely function-able we would test it and code it accordingly. Arms and the gearbox for the tray would be next this gearbox helps lifting the tray. After that comes up the stack tray this would carry the cubes and handle them which would supported by the gearbox , Then well work on the claw that feeds this Robots tray
