Whakatae - LEGO Education SPIKE Prime Competition Box robot
- 27 Jul 2020
With tutorials, courses and building instructions with gears you could learn how to use Gear Wheels, Warm Gears and Racks. Everything spins. With a few gear wheels you could make it spin faster or harder. Check out the examples of different constructions, robots and attachments that make use of gear wheels.
Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.
This is an active attachment with gears built from LEGO Education SPIKE Prime robotics set. The goal is to do a precise drop. The attachment could be used for both cargo items.
This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.
The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.
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.
When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.
Build with LEGO Mindstorms EV3 parts.
This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 9th mission of the FLL Cargo Connect competition.
We took a stab at building a box robot entirely with chains. It is difficult to find these chains. They were part of the original LEGO MINDSTORMS NXT Robots, but we had an idea. Can we power the whole box robot and all the attachments with the chains. This allows us to do a nice demonstration when and how chains could be used.
To build the robot you will need about 180 of these the chain pars - 3711a. They could be found from NXT and from some technic sets.
This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.
This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears
Instructions for a simple Crane construction built from LEGO Mindstorms EV3 set. In order to operate properly, you need to add weight at the back of the jib. The most interesting part of the robot is the design of its hand, so examine it closely.
A robot attachment placed on the right side of the LEGO Mindstorms Box robot chassis. It uses two gear wheel to move a level. The level could collect things.
This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!
It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.
Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.
This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees.
It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion
Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.
The left attachments work synchronously, and the right attachments are also synchronized couple.
These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us.
Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.
Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.
Francesco 2 is inspired by the robot Francesco.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels. Differently, from Francesco, Francesco 2 has space where a locking mechanism is meant to be built for the differential.
The CubeHunter uses the ultrasonic sensor to detect a ball or cube. Next, the robot catches it and reads the colour of the object using the EV3 colour sensor. The building instructions are suitable for classes with students and if you are working alone at home.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
