Sensors: In addition to the physical robot, we had to make a ultrasonic sensor set up to eventually attach to the body. These sensors were going to be hooked up to the motors to allow for the robot to navigate the world, turning and stopping where necessary.
Building process: Unlike the other robots, for the Tamiya robot we had to build it from scratch. This included screwing together plastic and wood parts, attaching gears to bars, even making our own battery case. This process was slow but steady and we managed to physically construct the robot with minimal issue. One big problem we did run into was accurately measuring locations of gears on the bars, and this led to us having to remake our gear box a couple times to ensure everything lined up properly.

Single Motor: When we first created the body of the Tamiya, we created a simple, single motor that controlled both sides at once. Although this motor did not allow for turning, it did work going both backward and forward depending on the direction of its switch.
Double Motor: When we attempted to attach the double motor onto our Tamiya we ran into a few issues. The double motor had two separate motors each controlled separately, but beause of this it was wider which pushed our back wheels out farther than those in the front. This meant when we attached the treads they were balanced precariously and would fall off after only a few feet of movement.
Sensors: We made our sensors separate from the Tamiya and they worked great, but we were not able to attach them to the robot due to the issues with the wheels on the double motor version.
The white brick is the databot that was unfortunately not finished due to poor time management. The reason behind the poor time management was due problems in the double motor. The bumper sensors were also not properly attached for the same reasons as before.
