Remove the arm

On the original robot, you have an arm and we've removed this arm to free some space for the controller and for the rotating plate. When removing the arm try to keep the pieces together. 

Change the directions of the robot

We've changed the direction - what was previously considered the front of the robot is now considered the back of the robot.

Move the controllers

The controllers are on the back to free space for collecting. With the controllers, we removed the C-sections from he front and increase the volume. 

Improved the phone holder

We modified it slightly to hold the phone more easily.

FTC PushBot Modified Robot for Collecting Balls with Plastic Plate

These are buliding instructions for the FTC robot and collecting attachments with it. We are doing small modifications of the push bot.


Let's discuss what are the modifications of the PushBot that we made so that we have the attachment at the front and some space for this attachment to work. The first important modification is that we've removed the arm of the robot. And on the original PushBot you have an arm right here at the top of the robot and we've removed this arm to free some space for the controller, for this mechanism for collecting the balls. And that's the first important modification. It will take you probably a couple of minutes 10-15-20, probably more to remove the arm. And as you remove the arm, try to keep all the pieces together because you will not be using all the pieces from the arm but just some of them like the motors. So, first thing, remove the arm. The second important modification is that we've changed the directions of this robot. Initially on the PushBot this was the back of the robot while this was the front of the robot and currently on this modified version of the PushBot we consider this to be the front of the robot. So, the robot is moving forward and is collecting some balls. Again, you can change this and you can think of the different sides in different ways but for these few tutorials we'll use this side of the robot and we'll name this side of the robot as the front part of the robot and this one is the back part of the robot. Third important modification for the PushBot is that we've moved the controllers at the back. And all the controllers are here with all the cables and we've modified the front side of the robot first initially on the PushBot there were some C-sections. Now, we'll refer to these parts here as C-sections because they kind of look like C - like the letter C. So, these C-sections were other parts at the front of the robot, we've removed them and we move them slightly to the back and there were some C-sections here and again we removed them and we've constructed only one C-section right here at the middle of the robot. And depending of course on the topic, on the task and what exactly should be collected you can move these C-sections to the back or to the front and reduce or increase the space right here, the volume in which you place the different balls. And finally we added one of the motors that were used for the arm and we've moved this motor. It was right here and we added this motor to the front of the robot. The last modification that was again important is that we've improved the phone holder right here. And if you follow the instructions for collecting, you would have a phone holder that can keep the phone quite stable. And these are the important modifications for our robot. What you should try to do now is if you have the PushBot, modify your PushBot to look like this. We have the building instructions for this robot and if you don't have the PushBot, construct this robot so that we can continue in the course.
