4th Day

• We started the day doing the blog.
•  Then we had to program the robot to use sound and touch sensors. 
• Also we had to build, improve and program the robot for the next day to participate in sumo. 
•  What we did was put color sensors and distance to the robot so it does not get out of the circle and follow the other robots.
•   In the afternoon we did the blog and scratch for the next day as our partner Nacho was not with we.
