Originally devised by Kavya and Navya, the Pull/Lift arm proved inadequate, leading to the creation of the sturdier Push arm. Nonetheless, Saanvi and Pranav repurposed the Pull/Lift arm for tasks like the Oil Platform, Power Plant, and Smart Grid. Its initial design with two black quarter-circles and a blue piece lacked stability, prompting the addition of extra components on each side for improved robustness. 

Employing the Sweep Arm for gathering water reservoir and solar farm units, Pranav and I were motivated by observing other teams' approaches. Our initial attempt with the Pull/Lift arm proved inadequate due to size constraints and unit loss. Drawing inspiration from successful methods, we devised an effective design to gather and transport units from the hydroelectric dam and solar farm missions.

Teammates Arya and Prabhjot utilized the Drop Arm for our missions, with initial struggles. Pranav supported us by creating the initial arm, but weight issues led to the energy units falling all over the board. We stabilized it by reducing its height. To prevent energy unit issues, we added a securing stick on top. With these adaptations, the arm functioned well. In the toy factory project, we encountered occasional drift but ultimately achieved success

For the Hybrid Car task, we developed the Hybrid Arm, initially attempting a complex and heavy design. Recognizing the need for a simpler approach, we crafted a smaller arm that proved equally capable. The initial choice of a pull/lift arm proved impractical due to its size, incompatible with the car's lever. Through iterations, we optimized the design, resulting in an efficient Hybrid Arm that now operates in conjunction with the push arm. Navya accurately highlighted the challenges we faced, prompting us to refine the arm's design for better performance.

The Hang Arm, designed for suspending water energy units on the hydroelectric dam, underwent improvement. Our initial attempt with an arm that went over the mission was facing weight challenges which led led to the development of the current, but longer arm. However, similar issues persisted. We experimented with side approaches but faced low success rates. Ultimately, we devised a front-reaching arm that extended units and facilitated placement on red hooks. Despite trial and error, we achieved success in hanging the units.

One group, Kavya and Navya, tackled the TV, turbine, and hybrid car missions. Initially,  the Lift/Pull (above) arm was not strong enough in pushing the Wind Turbine. To address this, we designed the Push arm. It effectively pushed the TV and  the turbine. We reinforced the arm by attaching it under the robot for more force, achieving the intended unit drop due to the whole robots' effort in turbine pushing, not solely relying on the motor.
