26.3.2. Collaboration Model

TyBOT is an autonomous robot designed to tie rebar intersections, which is a repetitive, labor-intensive job in bridge and highway construction.

TyBOT is specifically created to automate the process of tying rebar in construction projects. Rebar, or reinforcing bar, is used in concrete to provide strength, and tying it correctly is crucial for structural integrity. This task is often repetitive and can lead to worker fatigue and injury. By using TyBOT, construction teams can reduce the physical strain associated with this task as the robot takes over the repetitive tying work, allowing human workers to focus on more skilled or complex tasks.

Imagine cooking in a busy kitchen where a chef has to chop vegetables repeatedly. If a robot could handle that repetitive task, the chef could then focus on preparing the complex flavors of the dish without getting tired from all the chopping.

• Human teams place rebar mats manually. • TyBOT moves along the mats and autonomously identifies and ties rebar intersections.

In the collaboration model, humans and the TyBOT robot work together in a coordinated manner. The human workers first prepare the site by placing the rebar mats, which is a crucial step before the robot can begin its work. Once the mats are ready, TyBOT can autonomously navigate over them and identify where the ties need to be made, using its sensors and programming to tie the rebar accurately. This model allows for efficient work processes where each entity—human and robot—performs the tasks it excels at.

It's like a basketball game where the point guard manages the play by passing the ball to the center who is able to shoot. The point guard sets up the plays, while the center focuses on scoring, each contributing their strengths to achieve a win.

• Reduced labor requirements by over 50%. • Improved job site ergonomics.

Using TyBOT in bridge construction has led to significant reductions in the number of workers needed on-site. By automating the tying process, construction teams can use their workforce more effectively—perhaps reallocating them to other tasks that require human skill. Additionally, the ergonomic design and operation of TyBOT contribute to a safer job site, as workers are not subjected to the same physical demands of rebar tying, ultimately reducing the risk of workplace injuries.

Consider how a warehouse has adopted a conveyor belt system to move boxes instead of workers carrying them manually. This change not only cuts down the number of workers needed to do the same amount of work but also helps to prevent injuries from lifting heavy loads.

• Freed human workers from repetitive strain tasks. • Ensured speed and uniformity in tying.

One of the major outcomes of using TyBOT is that it relieves human workers from the physically demanding task of tying rebar intersections, which can lead to repetitive strain injuries if done excessively. Furthermore, TyBOT ensures a consistent quality of work as it ties the rebar with precision, which enhances the structural integrity of the constructions. This leads to faster completion times, as the robot's efficiency allows for quicker project advancements.

Think about how a lawn-mowing robot allows homeowners to have well-manicured lawns without them spending hours outside doing it themselves. The robot ensures uniform cutting and allows homeowners to spend their time on more enjoyable activities instead.
