1. Service robot overview
Service robots cover delivery, cleaning, guiding, and inspection. They report location, status, and video over 4G, and the cloud dispatches them. SimtoLink supplies robot makers with 4G, a shared data pool, a private APN, and an API into the robot cloud platform.
2. Typical applications and connectivity needs
Service robots cover delivery, cleaning, and guiding. Bandwidth and response time differ by job:
Delivery robots and takeout
Delivery robots report location and status over 4G, for cloud dispatch, elevator handoff, and pickup notices.
Cleaning and floor-scrubbing robots
Cleaning robots report sweep data over 4G, for remote control, task assignment, and consumable warnings.
Guide and inspection robots
Guide and inspection robots report video and routes over 4G, for remote guiding, security patrols, and anomaly alerts.
OTA and remote maintenance
Robots take OTA updates and remote diagnostics over 4G, for firmware updates and fault finding.
3. Core connectivity requirements
- Live location and status: Industrial and service robots have to keep reporting location, task status, and sensor data so the dispatcher can decide in real time.
- HD video backhaul: The onboard camera sends a live picture for remote watching and AI analysis, so the link needs steady high bandwidth.
- Remote control and OTA: Commands, task dispatch, and firmware updates go out over the air, so fewer technicians have to go on site.
- Multi-robot coordination: An AGV or AMR fleet works as a group. Robot-to-robot traffic needs low latency and high concurrency, and a 5G private network is the first choice.
- Safety and collision avoidance: The safety link has to stay highly reliable. If the network fails, the robot should emergency-stop so people and equipment stay safe.
4. IoT SIM card comparison and recommendations
Sub-scenarios differ in standard, bandwidth, and power. Match the card to the robot and the job:
| Use case | Recommended standard | What matters |
|---|---|---|
| Industrial robots, AGVs, and AMRs | 4G/5G | Location, fleet dispatch, live video |
| Service robots (guidance and delivery) | 4G | Remote monitoring, OTA, task management |
| Inspection robots and drones | 4G/5G | Video inspection, anomaly detection, command and control |
5. Data demand and usage
A robot uses about 500MB-3GB a month, mostly video and images. Pool by robot type, keep a 20%-30% buffer, and use a private APN.
6. Security and compliance
The security level is medium. The link needs TLS/SSL, a private APN, and an IP allowlist. SimtoLink provides one-stop real-name registration.
7. SimtoLink recommended solution
For smart robots, use 4G IoT SIM cards on service, delivery, and inspection robots. They roam a wide area, have to report location and status live, and need remote maintenance. The core advantages are 99.9% network availability, multi-operator network selection, a shared data pool, and an API into the robot cloud platform.
8. Implementation guidance and best practices
Move a robot rollout through these steps:
Choose the card by robot type, confirm coverage at the site, set the APN and allowlist, and alert at 80% of the data allowance. SimtoLink covers the full process. Contact us for a plan sized to the fleet.
