Scorpion Robot
This Project was submitted to Parallax by Shane Washburn
This robot competed in the preliminary rounds of Comedy Central's popular Battlebots television show. Shane uses a BASIC Stamp® 2 module and the Board of Education® programming board for the robot above (Yes, he traveled to the Sahara desert to take this picture!). He enjoyed the re-pluggable capabilities of the Board of Education carrier board when he was building his circuit. The stamp is controlled by feeding a pulse into three different pins. This enables the robot to travel forward, backward, turn left, and turn right. The third pin allows the user to control the speed of the sequence.
It is important to remember that the actual pneumatics that power the robot are only so fast, therefore the sequence must not go faster than the legs can react. The leg sequence is a set of high-low pins, one for each leg to lift and drop as well as rowing/swaying forward and back. In the proper sequence, this makes the robot go forward back and turn left or right. Shane programmed the stamp with a USB to a serial adaptor running Virtual PC on his iMac.By having the Mac in the pits during the battle, he was able to download new software versions on the fly as the robot was running. |
