Robotics
The field of robotics has exploded in recent years. This is in large part due to increasingly smaller circuitry and thus more powerful computational power. Capek (a Czech playwright) was the first use of the word "robot" in his 1921 play (R.U.R) about machine factory workers rebelling against their human masters. occurred in a play about mechanical men that are built to work on factory assembly lines and that rebel against their human masters. In fact robot is derived the root czech word for 'force labour' or slave.

Asimov, a Russian born US sci-fi author developed the concept of robots further and proposed a set of laws to govern robot behaviour
While we think of robots as modern inventions, in fact in some ways we've had robots since the Egyptian dynasties and throughout the ancient world were powered by everything from water, to springs (in the middle ages)
Through the modern era robots have been used to replace humans in increasingly sophisticated jobs

By the 1950's
By the 1970's robots were being controlled by large computers and replacing tedious and often difficult jobs
By the 1990's nearly everything that was easily replaceable by a robot had been

But don't be confused in thinking assembly lines are the only place for a robot. Distribution centres, shipyards, offices, anything is fair game when there is repetitive work not needing a human's ability to judge complex situations

Components of a typical robot
Components of a typical robot
Power Supply - The working power to the robot is provided by batteries, hydraulic, solar power, or pneumatic power sources.
Actuators - Actuators are the energy conversion device used inside a robot. The major function of actuators is to convert energy into movement.
Electric motors (DC/AC)- Motors are electromechanical component used for converting electrical energy into its equivalent mechanical energy. In robots motors are used for providing tortional or rotational movement.
Sensors - Sensors provide real time information on the task environment. Robots are equipped with tactile sensor it imitates the mechanical properties of touch receptors of human fingerprints and a vision sensor is used for computing the depth in the environment.
Controller - Controller is a part of robot that coordinates all motion of the mechanical system. It also receives an input from immediate environment through various sensors. The heart of robot's controller is a microprocessor linked with the input/output and monitoring device. The command issued by the controller activates the motion control mechanism, consisting of various controller, actuators and amplifier.
Assignment #15 - Robot Races
Assignment #15 - Robot Races
Race Rules
1. Only build at front desks (not at computers or at electronics area).
2. You can only use parts that are on your inventory list.
3. Robots cannot be bigger than 30cm by 30cm by 30cm.
4. Hands off once built (except for arduino based which can be controlled wireless if desired)
5. Students are to race out to a 10m line, cross and/or stop on it, then race back to the start line. The student(s) that crosses the start line again will be the winner of the competition

Lego Rules
1. Only build at front desks (not at computers or at electronics area).
2. You can only use parts that are on your inventory list unless you're trying an arduino competitor.
3. Individual time and distance competition
4. Controlling can be done however you want (sequenced code, sensors etc...)
Assignment #17 - Sumo Battle
Assignment #17 - Sumo Battle
Lego Rules
1. Only build at front desks (not at computers or at electronics area).
2. The competition is entirely hands-off
3. Bracketed Pairs and Battle Royale competitions for pushing each other out of the ring.
4. Winner is determined as 'last man standing'. Loser is the one that is pushed off/falls off. If both players fall off the board as a result of entanglement (or falls within 15s) it is a redo using the existing state of the robot.
5. If there is no win as a result of both robots being stuck/entangled/not-engaging within 30s it is a stalemate and both contestants re-place their robots at a 45deg. angle on their start lines
6. Arduino robots can be controlled remotely
