Introduction to Robotics Experience

I feel that i have not learn't as much as i though i would in robotics.

During this time i have worked with robotics the construction have probably not been necessary for me. I know enough about constructing robots from the old Lego robotics to be able to build many things. I have for example built a robot that can climb on bars. I felt that this part was unnecessary for me to do.

The programing that we where supposed to use was to easy so i kept trying to take it up another step and develop more sophisticated programing then we where supposed to have. I haven't learn't a lot from the basics that we where supposed to work with. I have done other things like a avoidance program avoiding cans that are in the way.

The thing that i learnt most from was about the sensors. I learn't how to work with threshold and how to Detect, sense and most importantly interact with the enviornment. I have learnt most also from taking the tasks one step further then before.

Most of the time we have used Fysics (math in use) to predict behaviours and draw conclusions by observing what is correct. I feel that i haven't deepend my understanding in science or math here but i did have a slight improvement in my knowladge about technology but not as large as i would like.

In my view this course was to easy for me i needed to take a harder level of robotics

Tractor challange

This is our last challenge of the year. It is called the tractor challenge. WE are supposed to pull a sled with weights. For the tractor challenge we need to change the gears on our robot and program the robot so it is very slow to be able to move the weights.

Drag race

Last class we had a drag race. In the Dragrace the robot was supposed to go 3 meter and win the race. So we had to make it as fast as possible. We tried a very high gear ratio. We did not have enough torque so the robot went slower. we had to pull down the gear ratio. As we did not have time to build a new robot we had to use the taskbot.

The picture is of the robot i would build and use if i had the time. It is generated in LDD. The wheels would be changed but LDD only has these wheels

Gears and Speed invistigation

In the gears of speed investigation we had two Hypotheses

First we find a value that we could compare the other values to. That means we tried to find Speed 1 and we used a number with the wheel ratio of 1 and running for 3 sec for gear ratio 1. We then measured the length of how long it traveled and the calculated the speed of the robot.

After predicted what the speed of speed 2 would be if gear ratio 2 is larger then 1 or smaller then 1. in both Hypotheses


When we tested how fast it went if the gear ration is larger or smaller then 1 we found that the values where closer to the prediction of hypothesis B. Then we reached the conclusion that hypothesis B is true and Hypothesis A is false
