Building instructions for this part of the BigDaddy competition robot

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.

This construction uses a differential. Both wheels could turn with different speed and this makes a construction much more stable when turning. 

Third part of the LEGO Mindstorms BidDaddy Competition Robot. 

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

We've separated the BigDaddy robot into a few smaller modules. This teaches modularity and gives you the option to reuse some of the modules and to look at specific modules.

These are building instruction for a working automatic catapult with a motor and a touch sensor.

This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.

This frame holds the motor and ev3 brick used in the catapult. The frame is placed on top of the rotating base and thus could be easily rotated. The brick could be both NXT and EV3

Building instructions for a LEGO Mindstorms Catapult Motor and Touch Sensor that are used for triggers for firing objects

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

The "five minute bot with handle" gives an easy and intuitive place for children to hold it. It provides a stronger construction and cables are not included, so that adult assistance with the cables at the end of the building process is required.

These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.

The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
