Without the use of any motor, you can still accomplish a number of missions using passive attachments. You can still pull/push on different levers using only a beam or two connected to the frame.
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
Let us do a quick recap of the whole lifting mission and its solution
Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.
Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.
Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.
Using a number of axles, beams and rubber bands we collect many loops at once. This is an important part of every competition, mostly of the FIRST LEGO League.
In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.
In this episode we will show you how to build the FiveMinuteBot. We will make a quick overview of this Mindstorm Robot.
How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.
Building instructions for the robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements.
The robot is built from LEGO Mindstorms EV3 parts.
These are building instruction for a working automatic catapult with a motor and a touch sensor.
Building instructions for a VEX IQ attachment for throwing balls with rubber bands.
Following the Spy Bot, we have this new Spy Vehicle. Yes, yes it is using an ultrasonic sensor.
The building instructions are for a robot base that looks like a car but is not exactly a car and has a strange shape. Just like spy vehicles - a car, but not only a car and not just a car.
Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it.
We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.
It moves and it collects. It collects objects.
These are building instructions for a LEGO Mindstorms robot that could collect objects. It is not actually catching them and that's why we call it "Simple Catch Bot". The general case is to program it to move on the floor and collect some of the Mindstorms wheels and tires coming with the 45544, 45560 or 31313 LEGO sets.
Let's go fast. Large wheels on the back. A lot of torque, small wheels on the front, good aerodynamics. Here we go.
These are building instructions for a LEGO Mindstorms EV3 Drag Car.
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.
This robot is made to serve the best tea in the whole continent! It is based on the Easy Bot from EV3. As its predecessor it is based on LEGO Mindstorms EV3. It uses two large motors to move around. The best part of the robot is the cup holder, that has a cool cup that shows the KISS principle.
