I am a beginner in robotics.. and I need help in making 3 Animal Bots all 3 could be same which can walk, grab things and do a small trick.. I can make a simple bot with wheels which can walk... But I am getting confused and troubled with giving it a animal shape and I really don't know how to make it grab things or do a trick.. And the budget of the robot is 200$ so like I need to make 3 robots under 200$.. I can go over that but that is the official budget atm.. If anyone can help me int he slightest.. please! D:
