Box Robot Two Push/Pull Attachment with a Rack

Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things.

The attachment could be built from LEGO Mindstorms EV3 and NXT parts.

Box Robot Two. Push/Pull attachment with a Rack on the right side

Need to transfer circular into a linear motion. You need a rack. Here is an attachment with a rack for our box robot.

Courses and lessons with this Material

This Material is used in the following courses and lessons

Box Robot Two. Fewer parts and one motor. Simplifying a robot.

After the first box robot course and its enormous success, we decided to build a second box robot. This time with fewer parts and with only three motors. The EV3 set comes with one medium motor and this robot will be easier for new teams. It is also lighter and more simple. Take the course and learn the ideas that we have in mind in simplifying a robot. Use this course with students and try to experiment to make the attachments and construction even simpler.

Attachments for the robot

In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.

EV3 Basic Course. Introduction to robot programming, construction and sensor use

This course is designed for students, mentors and teachers that are completely new to LEGO Mindstorms EV3 robots and would like to start using them to learn, in classes or at competitions. It is quite different from previously built resources at FLLCasts because it makes no assumption on any previous knowledge and tries to introduce everything step-by-step.

LEGO Gears. Changing Orientation

Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle.
