You might want to consider something simple till you have a better understanding of robotics.well, in that cause i cant make it because i do not have the money to make it. Thank you for telling me before i started the project. I'm probably gonna try to make a seek and destroy robot then(thats why i wanted to make a cheetah/hound.). What would i need to make this? i could have a little beacon that it needs to locate or something? I am thinking of a 4 wheeled robot that can pivot its torso, or would it be funner/ better to make it bipedular?
