lego robotics week 7

this week we learned how to use the colour  sensor, the colour sensor works by for example going straight until it sees the colour red then do a right or left turn  witch is what our first challenge was

along with getting our robot to coast when it sees the colour and getting it to brake when it sees the colour. the colour sensor will only pick up a few colours (red,green,blue.black white and even  no colour )  fun fact if your colour sensor is working you will be able to see the robot wobble  a bit when it sees the colour our 2nd challenge was to get the robot to follow a black line on a white table our program didn’t work the first time but then we realised that we had the wrong colour set but it worked perfectly after we fixed it

 

touch sensor

this week we are learning how to use a touch sensor

first we added a sensor onto our robot

we where given 2 challenges to complete our first challenge was to get our robot to to move ford get the sensor to touch someone ‘s hand and stop it took a while to figure out how to use the sensor but after a while  we kinda got the hang of it our only small problem was at first we couldn’t get the program to connect to our robot we figured out one of our cords wasn’t plugged in properly

our next challenge was to get our robot to tap  wall with the sensor move back then do a ninety degrees turn our group started to make a program but we ran out of time to finish it

bye 😀

robotics week 5

 this week our challenge was to make our robot do a pivit turn our  group started by making  program to make our robot do a pivit turn(a pivit turn is where the robot moves in a circle with only one wheel\motor working) and guess what first time for everything it worked first time  .Our second challenge  was to make our robot say hello world whilst going ford  our only challenge was connecting our ford program to our word program but after we figured out  to drag a program to another  next we worked on getting a picture and sounds on our robot it didn’t work at first but after trying a few  things our robot was able to move ford whilst showing a picture on the screen  our group worked well in sharing the work load and persevering through challenging situations next week we are going to work on our touch sensor
