Robotics+Assignment

= Activity 1 = a. In the activity ‘50cm and no more’ we will learn how to make the motor travel at a distance of 50cm in a straight line. We need to familiarise ourselves with the programing software in order to complete the task.

b. Some factors that will affect the success of this mission would be the carpet floor because of the friction produced against the wheels. While completing this task we have to consider the radius of the wheels being 18mm.

=Activity 2= a. In order to complete the task ‘there and back again’ the robot has to move from its position on the start line across the other line 50cm ahead, turn around and return to the same position. There is going to have to be more programming required then the first activity. We are able to use the beginning of activity one but then extending it so that the robot reaches the line and comes back to its original position. For this activity we are going to need learn how to turn the robot at the exact degrees to make it back to the starting point. The duration also has to be altered so that the robot does not cross the line too far that it is unable to reach the destination. In order to complete this exact task we are going to have to do trial and error.

b. The factors associated with this task, is the fact that the carpet could cause friction therefore decreasing the movement with the robot and its position. To make this activity a success we have to consider the facts that there are obstacles in the class room, such as other robots and chairs and desks.

=Activity 3= a. In task three ‘Brace, Brace, Brace’ we are asked to attach an Ultra Sonic Sensor to avoid collisions with other robots. The robot must obstruct an obstacle or problem and adjust its sensor properties which will then avoid the collision and turn away from what is was encountering. As partners we are going to have to learn how to build and attach the sensor to the robot, so that is responds to the environment. We are also going to have to learn how to program the sensor to the robot using different ports and the loop system, so that it continually flows with the movement of the robot. This task is going to be more advance and much more of a challenge because of the new attachment which alter the ports, this could come as problem because the wires may become tangled. Therefore we are going to need to learn the ports of the robots which will allow the sensor to work.

b. Some factors associated with this task is that it needs a variety of space so that the robot can move around freely avoiding walls and barriers whilst running. Also to make this activity a success we will need to create obstacles if there isn’t a lot around. For example placing our foot out so that the sensor can react and we can film the robot doing its necessary task.

=Activity 4= a. In order to complete task four ‘Edge finder’ we are going to have to attach the light sensor to the robot. The aim of this task is for the robot to navigate safely around a square table top. It is going to need to roam around freely, measuring the level of reflection of light from the table top. When the light sensor goes over the edge the robot will then stop, reverse, turn around and move forward continuously until reaching another level of light reflection. Too perform this task accurately we are going to need to learn how to program, and build the light sensor onto the robot. With the knowledge from activity three we already know how to add a loop, stop, reverse and change direction, therefore making this activity easier.

b. Some factors that will contribute to this task is amount of area that takes up the table top, and the fall if the robot crashes of the table which may cause damage to the robot and can stop the robot from completing the task.

=Activity 5= a. In activity five ‘walls and edges’ the aim was to make a simple loop program which allowed the robot to respond to collisions using a touch sensor at the rear of the robot. The robot must navigate with its sense of feel, and then reverse away from any contact, turning slightly and proceeding forward until it reaches another object it may collide with. In order to complete this task we need to learn how to build the sensor and attach it to the robot, which will then need to figure how to program it using the ports.

b. For this activity to be a success there must be a amount of space needed so the robot can collide with objects for the sensor to work properly.
