In the past few months, we have covered a few awesome railgun videos by Ziggy Zee. In this latest project, he demonstrates a railgun robot (35,000 Joules) with a scope for increased accuracy. A RoboteX robot was used to complete this project.
There are 70 x 6000 microfarad capacitor that can be driven to 410 volts for 35000 joules. The above video shows this railgun robot in action.
