The drilling tool is used to drill holes in the template plates, the end plates that support the longitudinal reinforcement.
Fig. 10 shows a schematic of the drilling tool.
The drilling tool attaches to the robotic arm.
The drill is driven by the motor in the robotic arm, which connects to the drill effecter through a shaft.
The speed and torque of the motor are then appropriately adjusted to finally rotate the drill bit.
The drill bit can be changed either manually or automatically.
Based on the CAD drawing given as an input to the system, the drilling tool can drill the template plate at the given locations.
The control of the robotic arm during this time period is not a very difficult task because of the absence of reinforcement bars in the area during this time.
To ensure that the drilling tool reaches its intended location, it is important to work out the inverse kinematics with utmost precision.
Further, to ensure appropriate performance the drill must remain orthogonal to the template plate. Fig. 11 shows a screenshot from the visual simulation of the drilling tool in action.
