Arduino Robot - logo example sketch not working

hey guys,

i purchased arduino robot , went great until ran logo example sketch. robot gets stuck when turning either direction , program hangs. sketch did upload, following error low memory , stability problems:

sketch uses 25,958 bytes (90%) of program storage space. maximum 28,672 bytes.
global variables use 1,944 bytes (75%) of dynamic memory, leaving 616 bytes local variables. maximum 2,560 bytes.
low memory available, stability problems may occur.

the robot can turn when running motortest sketch (which way not give low memory error) know motors working fine.

i'm running os x 10.10.2 , arduino ide 1.6.4.

any suggestions on how logo sketch working, , on whether low memory errors normal appreciated.

thanks!
