The web site (see video description) has a program you can download for this project (and building instructions too).

OK, the timing trick used on the button here is a little tricky, so try something a little simpler, such as:
1. Pivot turn while button is held down, then
2. Drive straight while button is held down, then
3. Hammer when button is pressed
and repeat all of this in a loop. You will only be able to hammer after going straight.
Parts 1 and 2 can both use:
a) Wait for touch sensor press
b) Move block set to unlimited
c) Wait for touch sensor release
d) Stop (Move block set to Stop)

well i was tryin something even simpler my algorithm was
1. Move forward while button is held down
2. Stop when released (a given)
3. Hammer when button is pressed
I can get it to move but idk wht to put in the program to make it hammer while its not in motion

After stopping, the hammer part could be:
1. Wait for button press
2. Motor A down for 0.25 sec
3. Motor A up for 0.25 sec
You have to guess which direction is "down" for the hammer motor, so if it doesn't work, try switching them in the program.
