Dwell is a car built with a LEGO MINDSTORMS EV3 set. It uses the medium motor for powering the back wheel and one more medium motor for rotating the front wheels and thus turning. Of course, there is a differential at the back.
This robot is a simplified spinoff of the Box Robots (Box Robot 1 and Box Robot 2). It may be build with a single set, but it will require extra technic beams 7x5 with open centers.
The name of the robot - "Squmo" is derived from the ancient tradition of connecting two words to make on and hense - "Square sumo" because "Squmo".
It kind of looks like an Inuit. But it surely walks like one. Most of the time Inuit walk with special boots that allows them to walk on deep snow without getting stuck. This robot walks in the same way. It has large feet and it moves one after the other.
Роботът използва 2 Mindstorms EV3 големи мотора за да се отваря и затваря. Използва стоманено топче за перла и веждите му могат да се мърдат за да се променя изражението му.
This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.

Инструкции за конструиране на ЛЕГО EV3 робот с цветно колело, задвижвано от среден мотор. В задната си част роботът разполага и със сензор за цвят. Може да бъде използван в занятия с ученици за игра на развален телефон.

This is the good not so old Pesho Bot Chassis with a "two bars" lifting mechanism and a hand. It can be build with any set. Only the omni-wheels are extra, but what is a good robot without an omni-wheels.

This is a simple chassis that uses two motors to control the robot and two omni wheels at the back for greater maneuverability.

Инструкции за конструиране на робот, наподобяващ самосвал. Роботът разполага със среден мотор, с помощта на който каросерията може да бъде наклонена и товарът изсипан на подходяща локация. В каросерията има и сензор за цвят, с помощта на който самосвалът може сам да определи типа на товара, който пренася.
Инструкции за конструиране на прост кран от Лего Mindstroms EV3 комплект. За да работи правилно, трябва да добавите тежест в задната част на стрелата. Може би най-интригуващата част от робота е "ръката", захващаща обектите. Обърнете ѝ специално внимание по време на конструирането.
Where do you keep your robots? We like to keep them ordered....
Actually we lied. It is almost always a mess wtih boxes and parts everywhere. We had sum FUN building this IKEA Billy and putting some of the FIRST LEGO League Mission Models.
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.
This is a LEGO Mindstorms Boxing robot. The inspiration story goes like this "One day we though - Let's play SUMO at this robotics demonstration, but let's make it more interesting. Let's play sumo with Humanoid Robots". We decided to build a boxing robot. The goal of the robot is to press the touch sensor on the other robot and it could be very fun. Perfect robot for demonstration. It is controlled by a joystick using the Bluetooth connection.
Here are the joystick and the programs for the joystick and the robots.
This is the joystick for controlling Real Steel LEGO Boxing Robot. We use the bluetooth connection for communication between the two bricks.
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.
This attachment uses a connector ("(98585) Technic Connector Circular With 2 Pin Holes and 3 Axle Holes") with 4 pins to connect with a knob wheel ("(32072 ) Technic Gear 4 Knob") of the robot. Because both elements are parallel one to another there is no jumping effect.
The attachment uses two pins, but it is easy to attach and detach because it uses "(6558) Technic Pin Long with Friction and Slot". When you attach or detach the attachment the slots are keeping the pins strong on to the attachment.
Also an attachment connected to the robot in this way, can be move to the rigth knob wheel or to the left knob wheel.
In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments.
Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand.
