Building instructions for the Rubber Band Attachment
- note that I have added two angled beams and an axle to illustrate how you could use the slide as an active attachmen;
This robot looks a bit weird. Can you guess why? The motors are placed in opposite directions. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you tell both motors to rotate forward the robot will just rotate! To make the robot move forward, you will need to make one of the motors rotate forward and the other one - backwards.
The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction and this needs to be accounted for during programming.
One pumpkin spice latte coming right up! This robot is made to serve the best drinks in the whole continent! It is one of the simpler robots that can be made with the LEGO SPIKE Prime set and it uses two medium motors to move around. The coolest part about the robot is the cup holder where a "cup" can be attached or removed. Bottoms up!
User this flywheels construction for experiments in physics. Start rotating the wheel and they would accumulate energy. You can try to calculate this energy and to measure how fast it would be consumed.
The construction is built with LEGO Mindstorms EV3

You can attach a frame around the front wheels to make them more stable and to allow for better aligning. The module extends the front wheel built at BigDaddy Front - front wheels mechanism module for a large LEGO Mindstorms Competition Robot
The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set
Time flies when you are having fun! Luckily, we have this robot to keep us on top of our schedule. Tempus is a robot that is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes the robot simple to build and effective in showing how a clock works.
This robot is designed to easily lift a cup while still holding it upright. With its motor attached to the side of the hub, the robot can lift the cup to any angle you want. You could replace the LEGO cup and make it lift real cups with a few adjustments. Be careful around liquids though, the robot doesn't like beverages like you do!
In Robopartans classes we needed a few parts the the robot could lift in a competition. These is a box that is suitable for this
You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.
