For my robot manipulator design, I used an intake roller that uses a gear ratio of 1:5.  If L up is pressed on the controller, it will suck up the cub, or in this case, the "soccer ball" and keep it inside itself until you press L down and release the "soccer ball". This is what was used for my robot manipulator design.

In Lesson 3 of the BaseBot competition, we utilized an intake roller mechanism. The intake roller is connected to a chain and sprocket. The chain and sprocket is in turn connected to a motor.  When the motor spins forward, the intake roller will rotate forward. Vice versa. Rotating forward pulls objects in, and rotating backwards will release objects.

We utilized an intake roller mechanism to complete the Robot Soccer Challenge. To build the intake roller, we connected two gears to a chain-and-sprocket mechanism on the left side. Then, we added standoffs and rubber bands between the gears to create the intake. In the video, you can see the intake roller picking up the soccer ball by rotating the chain-and-sprocket. This transfers the rotary movement to the gears, which causes the standoffs and rubber bands to spin. The soccer ball is pushed into the car to easily move around. Finally, the soccer ball is released through the same process, but the chain rotates in the opposite direction. In conclusion, the intake roller was a useful addition in the Robot Soccer Challenge.

For the soccer competition, we used an intake roller.  This mechanism includes a chain drive, a set of gears, and 2 rubber bands.  For the chain drive, we used a 1:1 ratio to control the gears that the front.  The chain drive is extended so the motor wouldn't be in the way once the block gets collected.  Combined with 2 gears, 2 standoffs, and 2 rubber bands, this makes the front of the intake roller to spin and collect the soccer balls. To collect the ball, it has to rotate inwards to push in the ball.  To release the ball, you can rotate the other way to release and push the ball into the goal.  In summary, the addition of the intake roller supported our progress in the Robot Soccer Challenge.

In Lesson 3 Manipulators, we used a clawbot with a 1;1 ratio claw and a 3:1 ratio lift. When you held RUp, the claw would open. If you held RDown, the claw would close and hold the "ball". Pressing LUp would cause the claw to go up and holding LDown will cause the claw to go down.

For our robot manipulator design, My team used a Clawbot V2(Armani named it) which has a gear ratio of 3:1. The mechanism allows the claw to go higher and lower. We connected the claw with the gears by using 4 1x16 beams, 2 standoffs, and  4 rubber bands.

In Lesson 2 on BaseBot competition, I decided to construct an active manipulator. The active manipulator is a clawbot that goes in a rotary motion, bringing the claw up or down. The claw is rotated by rubber bands attached to standoffs. When the controller button L up or down is pressed, Motor10 spins and rotates a 3:1 gear ratio. This allows the rubber bands to move the clawbot to desired heights once it grabs a "soccer ball". This makes the soccer ball difficult to take away, but makes the clawbot vulnerable.

For my robot we went and choose motor groups design.We used the motor group that used a gear ratio of 12:36.If you press L on the controller it will lift the claw and get the cube or "soccer ball" and it will keep it in the claw until you press L again and it will go down and release the "soccer ball".

My Robot manipulator design , I used an intake roller that uses 1:2 ratio with sprocket and chain. When the R is pressed the intake roller spins and takes the cube. When it spins clockwise the intake roller will take the cube and when it spins counter clockwise the bot will spit out the cube.

For the robot manipulator challenge, my team and I decided to use the ClawbotV2.  The gear ratio for the mechanism is 3:1. The mechanism allows the claw to grab and then lift to let the block out of reach of other blocks. A downside to this is that it is very top-heavy meaning it will fall over if it holds it blocks and has the claw in the air.

In lesson 2, the challenge was to create an in-taker and manipulate it to take in the small cube/ball in and release it inside the goal. For this lesson, me and my partner tried to do something fancy and we failed all attempts. Then time was getting scarce so we decided to do something simple and easy. We purposefully made the bot bulky so it could be a goalie. We also added a claw-like hand I suppose. But to enable the hand to move we had to use a compound gear train ratio of 3:1. So when we press R up the hand goes up and the reverse applies to the R down. The bright side was that the bot was the perfect goalie and no bot can score besides the actual claw bot. It also won every tackle fight due to its heavy weight. But the downside was that it was lacking in mobility.

In Lesson 2, the challenge was to design an intake mechanism to capture a small cube or ball and release it into the goal. My partner and I initially attempted a complex design, but after multiple failures and limited time, we opted for a simpler approach. We purposely made our bot bulky to act as a goalie, ensuring it could block shots effectively. To enhance its functionality, we added a claw-like hand powered by a 3:1 compound gear train, allowing it to move up and down with the R controls. The bot proved to be an exceptional goalie, with no other bot able to score against it except the claw bot itself. It also won every tackle fight due to its heavy weight, though this came at the cost of reduced mobility.

The video is the same as Steven's.                                          In lesson 2, we had to make a special bot that used a manipulator to take control of the ball. We decided to use a lift claw (similar to Vex Clawbot V2). We chose to use the lift claw because we were able to grab the ball while lifting it up in the air. Then we were able to get to the goal without anyone trying to grab the ball from us. To lift the claw, we used a 3:1 gear ratio so that the two beams would lift at the same rate and keep the claw level. When we clicked the L up button, the claw would go up, while clicking the L down button would cause the claw to go down. To use the claw, we clicked the R down button to close the claw and the R up button to open the claw. The only problem with the bot is that it is very top heavy, so it can sometimes fall forward while the claw is in the air.
