Mechanical Construction
We started our design from these specifications of the robot.
• a dimension of about 25 cm of radius, 20 cm height
• a speed of about 1 m/sec
• sensors to avoid obstacles
• a camera that can be moved up and down
• power enough to move and transmit for at least 2 hours without
recharging
• the robot should cost no more than 250 euro.
In the development process we faced some problems due to the limitations
from the specifications. Main causes of these problems are related with
low-cost, that is coming with our design constraints.
The mechanical construction of the robot is focused on construction
of the robot chassis, motor holders, motor and wheel connections, camera
holder, the foam covering the robot, batteries and hardware architectures.
3.1 Chassis
The main principles for the construction of the chassis are coming from
similar projects from the past, which are the simplicity of assembly and
disassembly, the ease of access to the interior and the possibility of adding
